3 DR. KAARSBERG: Good morning.

4 Welcome to the first Lighting Standards

5 Meeting of 2012. I hope you're having a good

6 year so far. As I think a lot of you know,

7 I'm Tina Kaarsberg. I'm the project manager

8 for Lighting Standards and I'm also going to

9 try to be a bit of an emcee today. And I'd

10 like to give a special hello to the Web

11 participants.

12 (Telephonic interference.)

13 DR. KAARSBERG: Welcome to the

14 wonderful world of HID lamp Test Procedures.

15 The thrills, the chills, the excitement, the

16 drama. Okay, everyone, I guess, as per usual,

17 I'm going to turn it over to Doug to go

18 through the rules and regulations, I mean,

19 just the process. And the agenda, so take it

20 away, Doug.

21 MR. BROOKMAN: Thank you. Good

22 morning, everyone. This is the U.S.

3 Today is Thursday, January 19th, 2012. It's

4 our tradition to start with introductions

5 around the room, so start over here. Say your

6 name and organizational affiliation and you

7 can get used to turning these mics on and off.

8 Make sure the little green button is

9 illuminated.

10 MR. STEELE: Lindsey Steele,

6 MS. KOHL: Betsy Kohl, DOE General

7 Counsel.

8 MR. BROOKMAN: Okay, I guess

9 that's all for this morning. Thanks again for

10 those of you here, an early start on the day.

11 All of you received a packet of information

12 when you came in the door, as well as an

13 agenda. I'm going to run through this very,

14 very briefly.

15 Immediately following this agenda

16 review, there's an opportunity for brief

17 opening statements. Anybody that wishes to

18 raise any issues here at the outset, there's

19 an opportunity here to do so.

20 Following that we'll have a

21 presentation followed by the opportunity for

22 question, answer and comment on statute and

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 8'

1 context.

2 Immediately following that, we're

3 going to talk about the proposed HID test

4 procedures, the definitions and test methods.

5 We'll take a break midmorning or so, around

6 about 11:15.

7 Following the break, yet more

8 presentation materials on the proposed HID

9 test procedures, laboratory accreditation

10 program, test measurements and calculations.

11 And around about noon or so, after that

12 discussion on presentation segment is

13 concluded, there's an opportunity yet again

14 for closing remarks, any other issues that you

15 would like to raise at this point in this

16 public meeting.

17 So that's the plan for today.

18 Questions and comments about the schedule or

19 about this? Anything that's not covered that

20 should be covered? We're good? Okay.

21 I'd ask for your consideration.

22 I've jotted up what I think are common

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 9'

1 courtesies. Please speak one at a time.

2 Please say your name for the record each time

3 you speak. I'm going to be queuing

4 individuals by name as best I can to speak. I

5 will also wish to encourage follow-on

6 comments, I find that might be useful, the

7 back and forth, for the Department. Please

8 say your name when you speak.

9 Please keep the focus here, turn

10 your cell phones on silent mode and limit your

11 sidebar conversations. We've already gotten

12 used to hitting the little on/off button on

13 the microphone, so please speak into the

14 record, there'll be a complete transcript of

15 this meeting.

16 DR. KAARSBERG: One more process

17 item. Some of you may have noticed that the

18 Federal Register notice says we're going until

19 2:00 p.m., but the agenda here has us stopping

20 at 12:30. That was just our best judgment,

21 once we actually went through everything we

22 needed to talk about, that's when we do think

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 10'

1 it will end. However, we have flexibility.

2 If you want to say more, we can go until 2:00.

3 If you want to say less, we can end earlier.

4 But I just wanted to note that for the

5 record.

6 And the other item is that we

7 will, in order to accommodate some of the West

8 Coast folks who were not able to get logged in

9 at 6:00 in the morning, for whatever reason,

10 we will be posting audio files as well as the

11 transcript on the website. And we'll also try

12 to make them as user-friendly as we can.

13 Okay, let's see what's next.

14 MR. BROOKMAN: And we should

15 probably also say we have folks joining us via

16 the web.

17 DR. KAARSBERG: Right, yes I was

18 mentioning that.

19 MR. BROOKMAN: And thanks for

20 those on the web if you'd please keep your

21 phones on mute, I think we've solved the echo

22 problem for now.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 11'

1 DR. KAARSBERG: Yes, and we're

2 going to -- So, Simone, how many web people do

3 we have right now? Sixteen, okay. So what '

4' we're going to do is stop of at the end of '

5' every segment in the agenda, so for us, the '

6' first segment would be like 9:45, we're going '

7' to ask for web comments as well. '

8' What's going to happen there is, '

9' if there are just a handful of web comments,

10 we will read them aloud and they will get into

11 the transcript. If it turns that there are

12 more than we can accommodate in the time,

13 which has happened in the past, the procedure

14 will be to have the ones that aren't read

15 aloud, to have them be appended to the

16 transcript as if they had been spoken, but

17 they'll be at the end. That's the best we

18 could do.

Oh, yes, is there any

19 reason we couldn't show them who's on?

20 (Off-microphone comments.)

21 MR. MYER: I defer to Simone.

22 DR. KAARSBERG: Okay, Simone's

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 12'

1 going to read the Web participants names

2 aloud. I think we have more on the web than

3 in person, or it's very close anyway. Okay,

4 so, Simone, do you have a microphone now?

5 (Off microphone comments.)

6 MR. BROOKMAN: Why don't you just

7 read the names of those who are on there?

8 MS. SYDNOR: So on the webinar we

9 have Becky Keubler, Carl Abramson, David

10 Ellis, David Woodward, Eric Andersen, James

11 Wang, Linda Wilson, Marge Holdsworth, Matthew

12 Swink, Rebecca Rainer, Robert Lingard, Ronald

13 Daubach, Rui Li, Scott Morris, Susan Callahan,

14 and William Hitchcock.

15 MR. BROOKMAN: Okay, thank you.

16 DR. KAARSBERG: Thank you. Now

17 we're finally getting to the meat of the test

18 procedures. We're going to review, present

19 and seek comments. And without further ado, I

20 would like to introduce the master of metal

21 halide, the sultan of sodium and the maestro

22 of mercury, our own hero of HID, Mr. Mike Myer

1 from Pacific Northwest National Lab.

2 [applause]

3 MR. MYER: Wow, tragically

4 everything from this point on is going to be

5 anticlimactic. Wow. Hopefully when we sync

6 this up for a podcast it can be like the old

7 60s Batman, pow. Thank you, Tina. So the

8 purpose of test procedures and today's NOPR

9 public meeting: One, we'll review the statute

10 and DOE's actions related to high intensity

11 discharge lamps.

12 We're also going to present the

13 proposed test procedure and ultimately it's

14 for comment from both people in the room and

15 the many others who are listening online and

16 via the web. And at this time, we'll do

17 opening remarks from around the room and then

18 we'll wait and then do brief opening remarks

19 from the web, as that works.

20 MR. BROOKMAN: If that works. I

21 saw Alex at the outset wanted to make a

22 comment.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 14'

1 MR. BOESENBERG: This is Alex

2 Boesenberg of NEMA and on behalf of the

3 manufacturers, I wanted to list a couple of --

4 six very brief summary topics that we have

5 gathered so far as we're crafting our public

6 comments, just some thoughts to keep in mind.

7 As always, we'll submit this in

8 writing. And some of these topics will be

9 commented on by some of the industry experts

10 as we get to those subjects through the course

11 of today's discussion.

12 One thing we want to point out is

13 there's an inconsistency in the NOPR right now

14 regarding the use of the terms measured and

15 rated, they're sometimes interchanged. A

16 measured value is very different from the

17 rated value and we will include some

18 suggestions as to how that could be clarified.

19 We note frequent mention of HID

20 ballasts in the document right now and want to

21 reaffirm that it's not a ballast standard, so

22 in most cases ballasts are not the appropriate

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 15'

1 topic. How a lamp performs will be measured

2 based solely on the lamp.

3 We noted some interchangeability,

4 or some confusion, we think, in the use of

5 lumen maintenance and life rating. The terms

6 L40 and L70 appear in the NOPR. The L

7 categories, if you will, are related to solid

8 state lighting, L70 being one of the more

9 common terms, and that is regarded when an LED

10 has lost 70 percent of its original, 30

11 percent of its original flux, thank you.

12 Anyway, the point we wanted to

13 clarify is that for HID we talk about 40

14 percent of life for metal halide and 50

15 percent of life for high pressure sodium and

16 mercury vapor lamps.

17 In most of the testing that has

18 been done to date, the bulk of the data that

19 manufacturers have on hand is about that 40

20 percent rated life. We want to stick to that

21 figure as often as able, because that means we

22 can use all our historic data and don't have

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 16'

1 to retest everything.

2 MALE PARTICIPANT: With concern to

3 lumen maintenance.

4 MR. BOESENBERG: Yes, as relates

5 to lumen maintenance. Another point we wanted

6 to bring up, or wanted to raise for your

7 awareness, is that a lot of HID lamp testing,

8 since it's not been heavily regulated in the

9 past, that testing has been done at factories

10 post-production.

11 And a lot of these factories, or

12 at least enough of them to concern us, are

13 NVLAP certified. NVLAP being the typical

14 certification that DOE allows something to be

15 tested, if we do testing in-house. So that is

16 a consideration regarding testing and the

17 capabilities and timing and cost.

18 We're concerned about delaying of

19 product to market if a full 40 percent life

20 test becomes required, because this is a very

21 long-lived light source. And so if we test 40

22 percent that's quite a long time, could be up

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 17'

1 to two years sometimes.

2 So we'll hope that there will be

3 options for beginning testing, doing some

4 initial values and then completing later. And

5 if, you know, settling out. We do that in

6 many other programs, whether it's DOE or

7 EnergyStar.

8 And, lastly, we do believe that

9 tests for correlated color, temperature and

10 CRI are appropriate but we want to point out

11 that variation of color within HID lamps can

12 be quite significant due to manufacturing

13 variation, and also in the lamp types and

14 their orientation during operation.

15 We don't think that lamp color,

16 whether CRI or CCT, should be a factor in

17 determining product classes for energy

18 efficiency testing. We do agree with the

19 possibility of its use as far as delineating

20 classes, particularly if those will be used to

21 set exempted categories.

22 But, I spoke briefly with Tina

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 18'

1 before we started and one of the points we'll

2 make and reiterate throughout the discussion

3 as it comes up is that the variation of the

4 products and production, production variation

5 more accurately, in HID lamp is quite large.

6 And when you're talking about something that

7 goes way up high on a pole or up in a highly

8 elevated ceiling, variation from one product

9 to another is not nearly as noticeable.

10 We have a much tighter band of

11 tolerance or production variation on consumer

12 products because they're usually right next to

13 each other in the fixtures there and when

14 there's a lot of difference, you'd notice it.

15 HID is not really in that

16 category, so we talk more about ranges of

17 performance than a single-point curve. And

18 some of my experts will talk about that later

19 on. And that's all I have, thank you.

20 MR. BROOKMAN: Okay. Other

21 comments, opening remarks, here at the outset?

22 No one else in the room? Did I understand

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 19'

1 you, are you thinking that if they want to

2 comment online, they can do so vocally?

3 MS. SYDNOR: They can, but we need

4 them, if they are not speaking, to mute their

5 phones because we are still getting a lot of

6 feedback.

7 MR. BROOKMAN: Okay, so once

8 again, I'd request from here at Forrestal, if

9 you're not -- please mute your phones because

10 we're still getting feedback on the line here

11 in the broadcast over the room.

12 But let me ask at this point,

13 anybody who's joined us via the web, would you

14 like to make opening remarks at this point? I

15 heard somebody, please speak up. Okay, good.

16 So thanks to all of you for muting

17 your phones, that's working better now. Then

18 let's proceed with the slides. Michael.

19 MR. MYER: Yes, regarding the

20 comments I think it is important to just point

21 out it is a lamp test procedure and at

22 periods/times, ballasts do need to come up for

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 20'

1 just different reasons. But I think those

2 will be apparent in the test procedure.

3 From time to time we'll see yellow

4 boxes at the bottom of slides. They are issue

5 boxes, they are a request for comment. They

6 do correlate to the NOPR itself in terms of

7 numbering and text. So at times we'll stop

8 and pause and ask for comment about the

9 material that was just presented.

10 In early December, the Federal

11 Register published this notice of proposed

12 test procedure. That started a 75-day comment

13 period and that 75-day comment period ends

14 11:59 Eastern on Tuesday, February 28th.

15 From here I will just briefly

16 touch on statute and context. And then I will

17 turn over the proposed HID lamp test

18 procedures to my colleagues, Lindsay Steele

19 and Heidi Steward.

20 Briefly the regulatory history

21 started out in 1975 with EPCA itself, Energy

22 Policy Conservation Act. That actually just

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 21'

1 started the whole program itself, creating the

2 authority for test procedures and energy

3 conservation standards.

4 A little bit after that, the

5 Department of Energy was directed to a

6 determination for HID lamps. The final

7 determination was published July 1 of 2010,

8 that did determine that test procedures and

9 energy conservation standards were technically

10 feasible, economically justified and would

11 result in significant energy savings.

12 That final determination then

13 started the next process of the test

14 procedure, which is where we are today with

15 the proposed test procedure, bringing us to

16 our process and our schedule.

17 We are currently in the NOPR

18 phase, shown by the green arrow to the left,

19 and we are moving into the final rule stage.

20 As I mentioned, the key dates here, the notice

21 was published December 15th, as I said before.

22 That starts a 75-day comment period which

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 22'

1 ends on February 28th. And a projected final

2 rule to establish test procedure will be

3 January 1, 2013.

4 At this time I'm going to turn

5 over the presentation to Lindsay Steele, who

6 will discuss standards and other related

7 aspects of the test procedures.

8 MR. STEELE: Good morning. Here

9 we're going to discuss the industry standards

10 for HID lamps that were used to develop these

11 test procedures.

12 DOE reviewed current industry

13 standards, best practices and technological

14 developments and concluded that the existing

15 industry test procedures provide all elements

16 required to measure the required parameters

17 and calculate the efficacy of HID lamps. The

18 next several slides will list the relevant

19 industry standards.

20 Part of the photometric lamp

21 characteristic measurements requires

22 determination of color rendering index and

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 23'

1 correlated color temperature, CRI and CCT

2 respectively, of an HID lamp's output.

3 I should mention DOE is

4 considering color metrics to delineate to the

5 equipment classes in the HID lamp energy

6 conservation standard.

7 The International Commission on

8 Illumination, or CIE standards referenced in

9 these test procedures, are shown here, CIE

10 13.3 and CIE 15. These standards will be

11 incorporated by reference into the Code of

12 Federal Regulations.

13 The HID lamp electrical

14 characteristics are contained in the combined

15 American National Standards Institute, or ANSI

16 Standard, C78.389. And the ANSI Standards

17 here contain details on the equipment

18 requirements, on lamp aging, warm-up,

19 stabilization and the electrical

20 characterization measurements themselves.

21 In the case of an HID directional

22 lamp, which will be defined in a few moments

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 24'

1 and discussed shortly, is basically a lamp

2 that produces a beam. And that standard

3 referencing directional lamps is ANSI C78.379.

4 And again, we're proposing to incorporate

5 these by reference in the Code of Federal

6 Regulations.

7 The last two standards needed for

8 these test procedures are from the

9 Illuminating Engineering Society of North

10 America, or the IES. The HID test procedures

11 require measurement of HID lamp lumen

12 maintenance. LM-47 contains the methods and

13 measurement details to determine lumen

14 maintenance.

15 As far as HID lamp output and

16 color measurements, those are described in the

17 IES Standard LM-51, and the references

18 therein. And again, we will be incorporating

19 these by reference in the Code of Federal

20 Regulations.

21 Finally, for this portion of the

22 presentation, a quick mention about standby

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 25'

1 mode and off mode energy usage. DOE regulates

2 HID lamps as commercial and industrial

3 equipment and they do not require measurement

4 of either standby or off mode energy usage,

5 unlike counterparts or products that are

6 considered consumer or residential which do

7 consider standby and off mode energy usage if

8 it's feasible to do the measurements.

9 HID lamps do not operate in either

10 standby or off mode. Their primary function

11 being to produce light. Therefore, DOE is

12 proposing not to measure either standby or off

13 mode energy usage in these test procedures.

14 At this point, I'll hand over the

15 podium to Heidi Steward.

16 MR. BROOKMAN: Questions or

17 comments so far? I see none. Okay.

18 MS. STEWARD: Okay, let's go on to

19 the actual proposed test procedures. We'll

20 start with definitions.

21 We looked at the definitions

22 within EPCA and determined six of them were

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 26'

1 relevant to HID lamp test procedures as

2 written. This is just housekeeping. We're

3 moving them from a subsection to a parent

4 section. We propose to adopt these with no

5 changes.

6 Within 10 CFR 430, we found four

7 definitions that are useful to this test

8 procedure. We propose to copy them from the

9 Consumer Code to Commercial Code.

10 The only change we propose is to

11 lamp wattage. We are trying to make it more

12 generic. The current version reference is in

13 IES standards to define the aging period. We

14 propose to broaden this to allow other

15 relevant industry standards to be used as

16 necessary.

17 We did determine that six

18 additional definitions were needed to create a

19 full test procedure so we will talk about

20 these more in the next few slides.

21 For more appropriate

22 characterization of HID lamps, DOE proposes to

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 27'

1 distinguish directional lamps by distribution

2 rather than [lamp] shape, which also allows

3 the possibility of future lamps having

4 different shapes or forms.

5 We reviewed definitions for

6 directional lamps with optical characteristics

7 similar to those of HID directional lamps, for

8 example incandescent reflector lamps, and

9 found that definitions for reflector lamps

10 typically focus on the construction of the

11 lamp and not the direction in which the light

12 leaves the lamp.

13 Existing HID lamps that would be

14 considered directional are offered in various

15 bulb shapes. For example, R40, R111, Part 20,

16 Part 38. Future lamps may take different non17 conforming shapes and forms while providing

18 similar light output delivery. Therefore, the

19 proposed DOE definition is based on the

20 directional delivery of light output and not

21 the construction of the lamp.

22 The proposed definition is based

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 28'

1 on the EU definition, which was adopted as the

2 standard by EnergyStar. So the proposed

3 definition for directional lamp is,

4 directional lamp means a lamp emitting at

5 least 80 percent light output within a solid

6 angle of pi steradians corresponding to a cone

7 with and angle of 120 percent.

8 In other rulemakings, NEMA

9 commented that efficacy doesn't work as a

10 realistic measure of directional lamps. So we

11 distinguish directional lamps with a lamp's

12 light distribution or beam angle.

13 So the proposed definition for

14 beam angle is, beam angle means the beam

15 angle, or angles, as measured according to the

16 requirements of ANSI C78.379, including

17 complex beam angles as described in ANSI

18 C78.379, Appendix A.

19 There are three types of lamps

20 covered under this HID lamp test procedure,

21 metal halide and mercury vapor lamps have

22 already been defined. We needed to add a

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 29'

1 definition for high-pressure sodium lamp, so

2 here it is.

3 NEMA recommended we propose this

4 based on ANSI C82.9, which is thus, high

5 pressure sodium lamp means a high intensity

6 discharge lamp in which the major portion of

7 the light is produced by radiation from sodium

8 vapor operating at a partial pressure of about

9 6,670 pascals, approximately 0.066 atmospheres

10 or 50 torr or greater.

11 DOE notes that EPCA defines lamp

12 efficacy to mean the lumen output of a lamp

13 divided by its wattage, expressed in lumens

14 per watt. This proposed definition interprets

15 the EPCA definition for the rulemaking. We

16 are using rated luminous flux because this

17 calculation is being used for a statistical

18 sample rather than an individual lamp.

19 Yes, there's a question.

20 MR. BROOKMAN: Yes, Susan, please.

21 MS. ANDERSON: There may be a

22 point but I'll wait until you finish all the

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 30'

1 definitions.

2 MS. STEWARD: Thank you. One

3 subset of HID lamps are the self-ballasted

4 lamps. They can be used as replacements for

5 other lamps in existing fixtures with no

6 external ballasts.

7 For example, a metal halide PAR

8 lamp might be used as a direct replacement for

9 a halogen lamp used in a retail space.

10 The proposed definition for self11 ballasted lamp for HID lamps is, self12 ballasted lamp means a lamp unit that

13 incorporates all elements that are necessary

14 for the starting and stable operation of the

15 lamp in a permanent enclosure and does not

16 include any replaceable or interchangeable

17 parts.

18 A basic model defines a class of

19 lamps that are similar in design and

20 specification to the extent that their

21 performance can be determined by a

22 representative sample. This definition is

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 31'

1 global and used for most basic models, not

2 just for lamps.

3 The proposed definition for basic

4 model is, basic model, with respect to HID

5 lamps, means all units of a given type of

6 covered equipment or class thereof,

7 manufactured by one manufacturer, having the

8 same primary energy source and which have

9 essentially identical electrical, physical and

10 functional or hydraulic characteristics that

11 affect energy consumption, energy efficiency,

12 water consumption or water efficiency and are

13 rated to operate at given lamp type and

14 wattage.

15 Again, this is a more global

16 definition, thus the hydraulics and water

17 portions. So our opening Issue 1a, DOE

18 invites comment.

19 MR. BROOKMAN: Susan, you're

20 first, but please use the microphone.

21 MS. ANDERSON: What we want to

22 start with is looking at lamp efficacy. And

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 32'

1 what we're concerned about is when it talking

2 about rounding the value to the nearest tenth,

3 because of the wide variation in measurement

4 you can get in HID lamps, you're lucky to

5 round to the nearest 100. You know, so it's

6 just not practical to round HID lamps to such

7 a small unit of measure.

8 MR. COOK: There's an implied

9 accuracy that's not achievable.

10 MS. ANDERSON: That just doesn't

11 exist.

12 MR. BROOKMAN: Okay, thanks,

13 Keith.

14 MS. ANDERSON: And the other thing

15 is that the appropriate definition for lamp

16 efficacy as far as the industry is concerned

17 is in IES RP-16, and we would refer you to

18 that. And them LM-51 being the standard that

19 describes how you measure it.

20 MR. BROOKMAN: Okay. Keith.

21 MR. COOK: Keith Cook, Philips

22 Electronics. Concerning your basic model,

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 33'

1 NEMA doesn't understand why that's being put

2 into a test standard. That should be part of

3 a lamp specification, not a test standard. So

4 it needs to be dealt with, I think, separately

5 from this particular activity.

6 MS. STEWARD: Thank you.

7 MR. BROOKMAN: And, Susan.

8 MS. ANDERSON: We would also,

9 industry would like to work with the DOE in

10 determining those basic models, too, to have

11 some input on that.

12 MR. BROOKMAN: Okay. Joe, please

13 go ahead.

14 MR. HOWLEY: Just one other

15 comment that we have talked about in industry

16 is that we really don't see the need to have

17 hydraulic or water consumption in the

18 definition of HID basic model. We think that

19 probably could be removed or it could be

20 confusing.

21 MR. BROOKMAN: Okay, thank you.

22 MR. COOK: It's dangerous.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 34'

1 MR. BROOKMAN: Has the Department

2 not determined what the basic models are yet?

3 MR. MYER: I'm going to step out

4 here, Michael Myer, Pacific Northwest

5 Laboratory. The definition with the

6 hydraulic, this is a standard definition used

7 for a lot of the terms for -- in the

8 certification, in 429. It works for a lot of

9 the technologies regardless of what it is.

10 It's kind of generic.

11 Also there's some, I don't want to

12 use the word ambiguity, but there's some

13 leeway in the manufacturers to determine their

14 own basic model rather than saying it's a 100

15 to 200 lumens type of metric. It allows the

16 flexibility of determination of the basic

17 model. That's why it's a broad definition.

18 MR. COOK: Regardless, I guess

19 we're still confused as to why we even bring

20 that up in a test standard though.

21 MR. MYER: You need to know what,

22 you're testing a basic model to --

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 35'

1 MR. COOK: No, you're testing a

2 lamp regardless of the model.

3 MR. MYER: I'm suggesting here

4 that you could use a 100 watt metal halide and

5 a 150 watt metal halide and they could be

6 characterized the same or you could separate

7 them out.

8 MR. COOK: But the testing itself

9 would be the same.

10 MS. ANDERSON: See, we just think

11 basic model should be part of the lamp

12 standard rulemaking, not the test and

13 measurement rulemaking.

14 MR. MYER: All right, we'll take

15 that under advisement and review.

16 MR. BROOKMAN: Okay. Good, thank

17 you. Joe.

18 MR. HOWLEY: Just another comment

19 on lumen maintenance. Alex mentioned this in

20 his opening comments. That just a continued

21 concern about lumen maintenance being

22 suggested at 70 percent of lamp life versus 40

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 36'

1 percent of lamp life for metal halide and 50

2 percent of lamp life for mercury vapor and

3 high-pressure sodium lamps.

4 That is the industry-standard way

5 that we've measured lumen maintenance for 50

6 years and that's what all our modeling and our

7 values are based on today. Also some concerns

8 about the use of rated values and measured

9 values in the definition as well were raised

10 within the group. So we'll provide some

11 further written comments on that.

12 MR. BROOKMAN: Okay, thank you.

13 Susan, please go ahead.

14 MS. ANDERSON: Yes, one other

15 thing about lumen maintenance and what I would

16 refer you to. Say for example, my company's

17 literature if you look at how we publish lumen

18 maintenance information for metal halide

19 lamps, in particular, it varies over a range.

20 I mean it's not like fluorescent or

21 incandescent or halogen where we can come up

22 with a specific defined --

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 37'

1 MR. BROOKMAN: Susan, I'm sorry,

2 you need to get closer to the microphone.

3 Thank you.

4 MS. ANDERSON: Okay. There's so

5 much variation in the lamps when we publish

6 our lumen maintenance curves we actually show

7 its region that the maintenance is going to be

8 within this region. It's not a single line of

9 data.

10 MR. BROOKMAN: So as Alex said at

11 the outset that's a standard characteristic of

12 these products?

13 MS. ANDERSON: These are discharge

14 lamps, yes. It's something that has to be

15 taken into consideration when setting

16 standards for these lamps.

17 MR. BROOKMAN: Okay, thank you.

18 Michael.

19 MR. MYER: Michael Myer, Pacific

20 Northwest National Laboratory. I just want to

21 followup on the comment about the industry

22 standard. That's not published anywhere, we

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 38'

1 did do some research, am I incorrect on that,

2 that there's no actual ANSI or document that

3 says 40 percent for HPS, 50 percent. And the

4 reason I'm following up for this is that

5 there's a statement about changing it now

6 would invalidate some manufacturers' data.

7 Characterizing the term, I think, accurately.

8 My concern is, do all

9 manufacturers use this value as of now, or is

10 it just kind of an industry, we all do it but,

11 you know, as I said, is there a document out

12 there that says that's what everyone does and

13 therefore all people do that?

14 MR. BROOKMAN: Susan.

15 MS. ANDERSON: You might want to

16 direct that question to Dr. Ron Daubach who is

17 on the line, or Susan Callahan that's on the

18 line. Ron Daubach is head of our test and

19 measurement group. And Susan is one of our

20 engineers for HID.

21 MR. BROOKMAN: So, Dr. Ron

22 Daubach, are you on the line? Can you talk to

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 39'

1 us?

2 MALE PARTICIPANT: Or Susan.

3 MR. BROOKMAN: Or Susan.

4 MS. ANDERSON: Or Susan Callahan.

5 The question -- Ron, are you on there?

6 DR. DAUBACH: Hello, can you hear

7 me?

8 MR. BROOKMAN: Now we can hear

9 you, yes.

10 DR. DAUBACH: Yes, I heard the

11 question but there's no consensus standard

12 that states that these lights test definitions

13 of 40 percent or lumen maintenance

14 definitions.

15 MS. ANDERSON: We did all agree

16 with the NEMA companies coming together to

17 prepare for this that all of us use that same,

18 that's what we use so that's what all of our

19 historic data is based on. Measured at 40

20 percent of rated life for metal halide, 50

21 percent of rated life for mercury and high22 pressure sodium.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 40'

1 MR. BROOKMAN: So is that an

2 established policy at NEMA?

3 MR. HOWLEY: Well, it is, what the

4 industry does, if you look in our catalogues

5 and you look at where ever we list lumen

6 maintenance data, we all list it based on the

7 same techniques. Forty percent for metal

8 halide and 50 percent for high-pressure sodium

9 and mercury vapor lamps.

10 MR. BROOKMAN: So irrespective of

11 whether it's an established procedure or

12 policy in NEMA, all of you use it and it can

13 be traced in your product literature?

14 MR. HOWLEY: Right, it's how we

15 have developed those numbers over the past 50

16 years and everybody uses the same life points

17 when they publish that data.

18 MR. BROOKMAN: Michael.

19 MR. MYER: Well, I had a question

20 related to a possible future energy

21 conservation standard. If they're, I don't

22 want to say competitive, or equal technology,

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 41'

1 is there an issue in rating one at 50 percent

2 and one at 40 percent of rated life rather

3 than not rating them point at the same point

4 in life? Also then you have apples to [ten5 apples comparison when you're starting to do

6 your lumen values over time.

7 MS. ANDERSON: If you look at the

8 applications of the consensus today, it's not

9 an issue, because mercury and high-pressure

10 sodium are typically used outdoors. And in

11 most cases high-pressure sodium has replaced

12 mercury.

13 By the time you get indoors where

14 metal halide is typically used, it's used in,

15 say, applications where at one time

16 fluorescent was used or fluorescent has now

17 replaced metal halide. Those are both

18 traditionally measured at 40 percent of rated

19 life.

20 So if you look at the applications

21 and where they're actually used and the other

22 sources that are used in those same

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 42'

1 applications, then they're measured at

2 comparable periods in the life timeline of the

3 lamp.

4 MR. HOWLEY: Right, I would agree

5 with that, Susan. High-pressure sodium --

6 MR. BROOKMAN: Joe Howley.

7 MR. HOWLEY: Yes. High pressure

8 sodium replaced mercury vapor over the past 50

9 years and that's why the data points were

10 similar, the lumen maintenance values were

11 similar, because generally customers were

12 looking at those two products and the lumen

13 maintenance of those two products.

14 When metal halide was developed it

15 often was competing against fluorescent for

16 high color rendering index type of

17 applications, which is why that became rated

18 at 40 percent to be equivalent to the 40

19 percent life ratings on fluorescent at the

20 time.

21 So that's why these values have

22 been developed over the past four or five

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 43'

1 decades the way they have. That's the kind of

2 historical basis. But more importantly that's

3 what all our data is tested on and all of our

4 ratings are based on, are those values.

5 So industry certainly would not

6 want to change this approach after all these

7 decades. We'd want to maintain the same

8 approach.

9 MR. BROOKMAN: Michael, do you

10 have any additional questions? Or DOE any

11 additional questions? No? Not at this time.

12 MR. MYER: Actually, I hope with

13 written comments, Michael Myer, Pacific

14 Northwest National Laboratory, that cannot be

15 expressed mathematically the spend of lumen

16 maintenance tolerance is what you're

17 describing, Susan?

18 MS. ANDERSON: We can certainly

19 show you data that we have that shows that

20 range.

21 MR. MYER: Thank you.

22 MS. ANDERSON: And, as I said,

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 44'

1 it's public information in our literature.

2 MR. BROOKMAN: Okay, thank you,

3 Susan. Alex.

4 MR. BOESENBERG: One other point

5 not related to this. I think we're finished

6 with that discussion. A point we wanted to

7 raise in at least two of the definitions, and

8 anywhere else in the rule it might appear.

9 I'll speak right now to the

10 definition of lamp electrical power input. It

11 defines total electrical power input to the

12 lamp including both arc and cathode power

13 where appropriate at the reference condition

14 in units of watts.

15 We want to point out that HID

16 lamps have electrodes, they do not have

17 cathodes. So there is no separation between

18 arc power and total lamp power for these

19 products. I think cathode is a carryover from

20 some other technology. Fluorescent

21 technology. So sort of a partial recognition

22 of that and when you say "as appropriate" we

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 45'

1 want to point out it's never appropriate.

2 MR. BROOKMAN: Okay, thank you.

3 That was a useful discussion. Any additional

4 comments on definitions before we move on?

5 And thanks again, for those of you that are

6 joining us via the web, for keeping your

7 telephones on mute. That's now working pretty

8 well here in the room. I'm going to go back

9 to Heidi.

10 MS. STEWARD: Thank you. This is

11 just a housekeeping definition. Alex, I know

12 you're going to love it. This is a ballast

13 efficiency definition. We are proposing to

14 standardize this definition across the

15 technologies, we are not proposing to measure

16 ballast efficiency for this. We are just

17 amending this definition to harmonize it.

18 Our proposed modified definition

19 is, "Ballast efficiency' means, in the case of

20 a high-intensity discharge fixture, the

21 efficiency of a lamp and ballast combination,

22 expressed as a percentage, and calculated in

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 46'

1 accordance with the following formula,

2 Efficiency = Lamp electrical power input

3 divided by ballast power input."

4 We have another issue box, so we

5 invite comment on the proposed amendment.

6 That ends the interpretive dance portion. And

7 I will be handing off to Mr. Lindsay Steele

8 for the test methods.

9 MR. STEELE: Okay, the next

10 several slides we're going to talk about test

11 methods for measuring energy efficiency of HID

12 lamps. Here we're going to talk about the

13 test conditions, equipment specifications and

14 measurement requirements for HID lamps in

15 these test procedures.

16 This will establish a standard

17 measurement practice, minimize potential

18 errors and obtain consistent and reproducible

19 test measurement results.

20 As mentioned previously in

21 comments a ballast is required to operate an

22 HID lamp, especially for stable operation.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 47'

1 And this was borne out in the metal halide

2 lamp ballast test procedure of 2010. And in

3 that test procedure an ambient temperature of

4 25C was required as well as an air speed of

5 less than a half a meter per second.

6 These are typical laboratory

7 conditions. They are quantified and

8 reproducible. And this brings us to Issues 2

9 and 3 where we're requesting comment on the

10 ambient temperature and the air speed

11 requirements as pulled from the metal halide

12 lamp ballast test procedure.

13 MR. BROOKMAN: Susan.

14 MS. ANDERSON: While this is

15 appropriate for ballast it is not appropriate

16 for HID lamps. The majority of the HID lamps

17 are actually a lamp within an envelope. So

18 they're totally enclosed. It's the arc tube

19 that's the lamp and then the envelope seals it

20 in. So air speed is not an issue whatsoever.

21 Where we do have double ended

22 lamps where it is the bare arc tube, those are

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 48'

1 tested inside enclosed fixtures, because that

2 is the only way they can be used, because

3 there are safety issues with those lamps. And

4 right now we have standards for up to the 400

5 watt double-ended lamps for those enclosures.

6 And the industry is in the process

7 now, already in the process, of defining

8 standards for those enclosures for the higher

9 wattage double-ended lamps. So in no case

10 whatsoever is air speed an issued when you're

11 testing HID lamps.

12 MR. BROOKMAN: Okay. Tina.

13 DR. KAARSBERG: Does the

14 established procedure in the enclosures have

15 any temperature requirements? Or any

16 requirements that are related to temperature?

17 MS. ANDERSON: I'm not enough of a

18 technical expert to answer that but Susan

19 Callahan from our company is on the line.

20 MR. BROOKMAN: Susan.

21 MS. CALLAHAN: Yes.

22 MS. ANDERSON: Susan is involved

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 49'

1 in writing the new standards for the higher

2 wattage lamps.

3 MR. BROOKMAN: Susan, did you hear

4 the question?

5 MS. CALLAHAN: Yes, I did. There

6 is no temperature requirement index.

7 MR. BROOKMAN: Okay.

8 MR. HOWLEY: HID lamps are not

9 affected by temperature to any great extent,

10 unlike fluorescent lamps, which there's a huge

11 temperature impact in operating a fluorescent

12 lamp. There really is no meaningful impact in

13 operating HID due to temperature range, the

14 normal temperature range.

15 MR. BROOKMAN: The normal

16 temperature range. Yes, Michael, go ahead.

17 MR. MYER: I believe the

18 temperature stated in LM-51, the temperature

19 range is --

20 MS. ANDERSON: I would ask you

21 address that to Susan Callahan.

22 MR. MYER: Susan Callahan, can you

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 50'

1 confirm that there is a temperature range

2 specified in LM-51?

3 MS. CALLAHAN: Excuse me?

4 MR. MYER: Susan Anderson asked if

5 you could confirm the temperature range, if

6 there is one listed, in LM-51.

7 MS. CALLAHAN: I don't believe

8 there is.

9 MR. MYER: If we could double10 check.

11 MR. BROOKMAN: Okay, so if you

12 could address that in your written comments

13 that would be helpful. Thank you, Susan. Let

14 me ask those who are joining us online to re15 mute your telephones, if you would please. I

16 have comments on this section. Lindsay, are

17 there issues that you want to raise at this

18 point?

19 MS. ANDERSON: The air speed is

20 also an issue with us.

21 MR. BROOKMAN: Right. Yes, okay.

22 Got that. Anything else you want to raise in

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 51'

1 this section, Lindsay?

2 MR. STEELE: No, nothing.

3 MR. BROOKMAN: Yes, please, your

4 name.

5 MR. MCGARAGHAN: Hi, Doug. My

6 apologies, I missed the introductions earlier.

7 This is Mike McGaraghan here on behalf of

8 California Investor-Owned Utilities, PG&E,

9 SCE, and separate utilities.

10 And I just had a quick question on

11 this. My understanding is that you're

12 incorporating ANSI C78.389 by reference and

13 then these two bullets here, ambient

14 temperature 25 plus or minus five. And then

15 airspeeds are listed. My read of 389 just

16 said "draft-free."

17 So I guess the question is are you

18 amending 389? And this will apply to, I'm

19 sure, a lot of slides today. Are you

20 incorporating by reference and making

21 amendments to 389? And if so can you identify

22 as you go through the slides where it's a

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 52'

1 change?

2 MR. BROOKMAN: Michael.

3 MR. MYER: This is Michael Myer.

4 I can address the draft-free comment.

5 Actually Keith Cook, many years ago, for those

6 in the room that may not know the story here,

7 the term draft-free was something we did in

8 the metal halide lamp ballast test procedure

9 because the air speed, my understanding, was

10 related to the stability. And it is

11 ambiguous, it says draft-free.

12 And in the final rule for Metal

13 Halide Lamp Ballast Test Procedure we did a

14 thorough review of multiple different

15 documents. IES LM documents, ANSI documents.

16 Not just lamps, but also fixtures and there's

17 a variety of different answers. Some gave

18 speeds, some of them had different speeds.

19 The term still is draft-free.

20 Keith, about two or three years ago at that

21 public meeting, Keith said in the old days

22 they did a tissue test. Meaning a piece of

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 53'

1 Kleenex, if it didn't move, that was their

2 definition of draft-free. That opened up a

3 whole new can of worms.

4 So we actually finalized on the

5 IEC definition of 0.5 meters per second

6 squared in that test procedure. Again, this

7 is, best way I would describe, is a

8 harmonization issue, because they used draft9 free and the question was raised at that

10 public meeting, what is draft-free. We then

11 published a final rule that set it at that

12 speed. So we were just continuing, again,

13 that draft-free issue into this rule.

14 MR. BROOKMAN: Okay, thanks for

15 the explanation. Yes, Mike?

16 MR. MCGARAGHAN: Great, thank you.

17 So the only follow-on there is just as you go

18 if you could try to point out if there are

19 places where you're adopting verbatim these

20 ANSI standards versus places where there might

21 be amendments to what's actually in the

22 standards. You may not always catch it but if

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 54'

1 you are aware of those that would be helpful.

2 Thanks.

3 MR. BROOKMAN: Additional comments

4 in this section, because we're about to move

5 on.

6 DR. DAUBACH: Can you hear me?

7 MR. BROOKMAN: Yes, please say

8 your name.

9 DR. DAUBACH: Hello?

10 MR. BROOKMAN: Say your name.

11 DR. DAUBACH: Hi, this is Ron

12 Daubach, Osram Sylvania. I think I missed a

13 little part of this and I heard some mention

14 of LM-51 having a ambient temperature

15 requirement. But that's qualified by saying

16 that it's primarily because of measurement

17 instrumentation and not due to lamp operation.

18 So I didn't know whether that was pointed

19 out.

20 MR. MYER: Although HID lamps may

21 not be affected by temperature is there a

22 value in setting the temperature for a

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 55'

1 correlation relative photometry or lamp

2 ballast factor.

3 Some of the other light loss

4 factors you need to correlate later on. You

5 know, this 25 degrees is a pretty de facto

6 standard for most light sources. Is there a

7 problem with setting it? This gentleman just

8 said that it's a testing equipment issue.

9 MR. BROOKMAN: Do you have an

10 answer for that, Ron?

11 DR. DAUBACH: Yes, there's a mic

12 here and I hear myself so I'm sorry. No, I

13 don't have a problem with the 25 plus/minus

14 five. I just didn't hear all of the question

15 that led up to that.

16 MR. BROOKMAN: So I thought that

17 previously Susan said that temperature range

18 was not a part of the LM, is that correct,

19 Keith?

20 MS. ANDERSON: No, my comments

21 were about airspeed. Let me clarify that,

22 about airspeed.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 56'

1 MR. BROOKMAN: Airspeed, okay. So

2 Michael, repeat your question so that Ron can

3 hear it again. Ron, here we go.

4 MR. COOK: He answered it I think

5 and I understand what's going on. Ron makes a

6 good point and the fact that really, again,

7 the lamp is not affected by it but the test

8 setup is affected by it. And as Joe pointed

9 out ballasts are very affected by the

10 temperature.

11 And so we may want to go back and

12 review the temperature requirements again,

13 because from a test setup standpoint if you

14 will be effecting the results of the lamp due

15 to the ballast itself changing then we may

16 want to hold that temperature a little bit

17 more precisely. So we will include something

18 in our written comments on that.

19 MR. MYER: Thank you.

20 MR. BROOKMAN: Okay, that made

21 sense.

22 MR. STEELE: Moving on. Now we're

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 57'

1 going to discuss the electric and photometric

2 measurements of the HID lamps. As mentioned

3 previously the electric characteristics are

4 based on the ANSI standards and the

5 photometric measurements are from the IES

6 standards with also reference to CIE standards

7 for the color parameters.

8 Again, we'll remind you DOE is

9 considering colorimetric to delineate the

10 equipment classes in the HID lamp energy

11 conservation standard and also point out here

12 that we have luminous intensity as a

13 photometric measurement and that is for

14 directional lamps to determine beam angle from

15 the light output distribution.

16 Okay, we'll move on.

17 MR. MYER: Actually, this is

18 Michael Myer. Going back to an earlier

19 comment about color temperature and ranges.

20 There is no chromaticity standard for HID

21 lamps, like there are for fluorescents and SL.

22 Can NEMA, when they provide

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 58'

1 written comments, provide what some of those

2 tolerances or ranges should be for color

3 temperature for the different, you know, plus

4 or minus what for a 4,000K lamp, because based

5 on some of the earlier comments.

6 MR. HOWLEY: We can discuss that,

7 Michael. We haven't yet but we can discuss

8 it.

9 MR. BROOKMAN: Keith, please.

10 MR. COOK: Keith Cook from

11 Philips. Wouldn't that be part of the lamp

12 standard though and not part of the test

13 standard?

14 MR. MYER: I would think that

15 would go both ways. You need to know whatever

16 tolerance you were testing to, I mean yes at

17 some value would be the standard, but when you

18 have to test to a tolerance. That's all I was

19 asking.

20 MR. COOK: You may have to specify

21 the accuracy of the test setup, like is

22 typically done for NVLAP approvals. But you

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 59'

1 wouldn't necessarily be looking at it for a

2 particular lamp.

3 MR. BROOKMAN: Yes, Joanna Mauer.

4 MS. MAUER: Could DOE describe a

5 little bit about the rationale for potentially

6 using color characteristics for establishing

7 equipment classes?

8 MR. BROOKMAN: Michael.

9 MR. MYER: Well, the rationale is...

10 it's still being explored. The Energy

11 Conservation Standard is still in development.

12 If you look at the European Union's they're

13 definitely different, they have an HID

14 standard and at certain color temperatures

15 there are different efficacy requirements.

16 For example, somewhere in the mid-5,000 range.

17 I don't remember if it's 5,000 or 5,500

18 kelvin. There's definitely a trade-off at

19 some point that you might have to change

20 something.

21 We also in HID determination heard

22 comments from NEMA, and others about,

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 60'

1 essentially high pressure sodium if efficient

2 but it has poor color rendering, low color

3 rendering, aspects in the 20s depending on a

4 standard HPS lamp. And it may not be a viable

5 trade-off for certain other technologies.

6 And so an equipment class might

7 effected that way. We have heard opening

8 comments from NEMA where they didn't

9 discourage equipment classes but said maybe

10 exclusions. So it's those type of aspects

11 we're still looking at.

12 MR. BROOKMAN: Tina.

13 DR. KAARSBERG: Yes, this Tina

14 Kaarsberg. I think it has to do with consumer

15 utility and the trade-offs because.This is

16 probably more important in some types of lamps

17 than in the HID. But we're still

18 exploring to what extent in those markets it

19 might it be important for customer utility,

20 what are the trade-offs, because if the

21 customer utility requires a certain type of

22 color temperature then what are efficiency

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 61'

1 trade-offs. Even though the

2 markets and applications are perhaps less

3 sensitive in this one, weare still exploring

4 that.

5 MR. BROOKMAN: Okay.

6 MR. STEELE: Moving along now with

7 the measurements of HID lamps. We're looking

8 at power supply characteristics. The test

9 procedures require specific power supply

10 specifications to obtain consistent

11 reproducible measurements. An HID lamp output

12 can vary with a little bit of variation in the

13 supply voltage. Obviously depending on the

14 technology under test.

15 So given the importance of the

16 supply voltage we're going to take some

17 precautions to minimize other contributions

18 that can affect the lamp voltage and current.

19 And this is quite a busy slide, but we list a

20 few things here that are from the standards

21 that address this.

22 In particular we've got the

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 62'

1 voltage supply wave shape being sinusoidal.

2 The harmonic content of the supply voltage.

3 And also the actual voltage regulation itself.

4 The last two bullets here on power source

5 impedance and the kVA rating is the ensure

6 that the power supply used is capable of

7 providing the appropriate power to the

8 ballast.

9 This brings us to Issue 4. We're

10 inviting comments on the proposal to

11 waveshape, voltage regulation, and power

12 source impedance requirements from ANSI

13 C78.389 in part and LM-51.

14 MR. BROOKMAN: No comments on

15 power supply characteristics.

16 MR. STEELE: Another precaution to

17 ensure consistent reproducible measurement or

18 reduce errors in the test results --

19 MR. BROOKMAN: Hey, Lindsay, hang

20 on. Comments?

21 MS. ANDERSON: My comments will be

22 about the next one.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 63'

1 MR. BROOKMAN: Okay, keep going.

2 MR. STEELE: Okay, sorry.

3 Reference ballast is required to operate the

4 lamp per manufacturer's specifications. We

5 don't want you to overdrive and damage the

6 lamps or underdrive them and skew the test

7 results.

8 You can also use a power supply

9 versus a specification ballast. Again, the

10 goal here is to obtain valid, reproducible

11 test measurement results. And that brings us

12 to Issue Number 5. DOE invites comments on

13 the proposal for reference ballast

14 requirements and the appropriateness of

15 adopting requirements as recommended in ANSI

16 C78.389.

17 MR. BROOKMAN: Joe Howley.

18 MR. HOWLEY: Yes, NEMA did discuss

19 this issue. Our comments are just to point

20 out that there, reference ballasts are not, of

21 course, required for self-ballasted lamps.

22 They are self-contained.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 64'

1 And also that at this time lamps

2 designed for operation only on electronic

3 ballasts do not have a reference ballast. The

4 industry has not created a reference ballast

5 for electronic operation only lamps. This

6 could create some issues going forward in that

7 area.

8 MR. MYER: This is Michael Myer.

9 Just if it's designated, it says it clearly in

10 the catalogue, electronic ballasts only and it

11 would have a different ballast catalogue code

12 so it's easily distinguishable?

13 MS. ANDERSON: I mean, in our

14 catalogue what we do is to list the ANSI

15 reference for the ballast that operates that

16 lamp, if one exists.

17 MR. MYER: So you would do like M18 47, you know, I'm must throwing --

19 MS. ANDERSON: Yes.

20 MR. BROOKMAN: So that exchange

21 there between Susan and Michael, back and

22 forth. So thank you, both of you. Other

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 65'

1 comments related to reference ballast

2 requirements?

3 MR. STEELE: Thank you.

4 MR. BROOKMAN: Mike, yes.

5 MR. MCGARAGHAN: So is NEMA

6 planning to propose reference ballast

7 characteristics that operate only on electric

8 ballasts, electronic ballasts?

9 MR. BROOKMAN: Susan.

10 MS. ANDERSON: That would actually

11 be something that would be done through ANSI.

12 And NEMA would work through ANSI to set up

13 standards. And that's still an evolving

14 portion of our industry, if you would have it.

15 So that's all very new.

16 MR. MCGARAGHAN: Okay.

17 MR. BROOKMAN: Susan, does that

18 indicate that that is something that is

19 underway or you're considering getting

20 underway? Or what is the status?

21 MS. ANDERSON: Susan Callahan?

22 MS. CALLAHAN: There's another

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 66'

1 company working on the test methods for

2 electronic ballasts. And it is my

3 understanding that the lamp manufacturers are

4 also working on what could be considered

5 electric ballasts for the market place.

6 MS. ANDERSON: Did everyone hear

7 that?

8 MR. BROOKMAN: I think that came

9 through clear enough. Okay, thank you, Susan.

10 MR. MCGARAGHAN: So when she says

11 we, she's referring to the committee?

12 MS. ANDERSON: Usually the way

13 ANSI standards for lighting evolve is that the

14 NEMA companies come together and come up with

15 standards and present them to ANSI. And then

16 ANSI typically adopts them. They become

17 formal through ANSI.

18 MR. MCGARAGHAN: And so, Mike

19 McGaraghan again. I guess a question for DOE.

20 Are you prepared to wait for an ANSI standard

21 to finalize this test procedure, or what's

22 your strategy to address lamps that can only

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 67'

1 be operated on electronic ballasts in the

2 meantime?

3 MR. BROOKMAN: Michael Myer.

4 MR. MYER: Michael Myer. I think

5 we'd research it more. Offhand I would guess

6 that electronic only would be a very small

7 percentage of the current market because they

8 would not be backward compatible since the

9 vast majority of the market is magnetic right

10 now. And then it also could be something

11 that, depending on other characteristics, they

12 would have other factors that would probably

13 be before it. But we'll do more research and

14 address it in the final.

15 MR. BROOKMAN: Okay.

16 DR. KAARSBERG: This is one of

17 those things, like many of these things, where

18 the test procedure and the standard need to be

19 in sync with each other. And we'll see how it

20 goes in terms of the way we look at market

21 shares and volume of shipments and those sorts

22 of things> That's part of the standard

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 68'

1 practice.

2 MR. BROOKMAN: Thank you, Tina.

3 Now, Joe.

4 MR. HOWLEY: Just a comment that

5 you may also look at this as an exempted

6 category since there are a very limited number

7 and they tend to be very high efficiency, if

8 there's no standards for them. Just a

9 possibility.

10 MR. BROOKMAN: So written comments

11 on that front I think would be useful.

12 MR. MCGARAGHAN: Another question.

13 Mike McGaraghan, on the issue NEMA raised

14 about self-ballasted lamps. Again, it goes

15 back to the question I asked earlier, what's

16 the DOE strategy for incorporating changes to

17 ANSI 389 in the federal test procedure?

18 Because that C78.389 doesn't mention a

19 procedure for self-ballasted lamps, that I'm

20 aware of.

21 So I think if you're going to move

22 forward with a test procedure that would cover

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 69'

1 them you would have to make a change to it.

2 Is that correct?

3 MR. MYER: Michael Myer, Pacific

4 Northwest National Lab. I think we would,

5 well first we would review it compared to

6 self-ballasted CFLs to see how they're

7 treating it. Obviously you couldn't have a

8 reference ballast because you can't remove the

9 ballast out of the bits.

10 Again, self-ballasted HID lamps

11 are also a very small market segment and we

12 might have to address it differently. But

13 research will be the starting point of, at

14 least, with other technologies that are self15 ballasted and then how it's applicable or not

16 applicable to this technology. And we'll

17 address it and I will.

18 MR. MCGARAGHAN: Another question

19 on ballasts. Lamps that are designed to

20 operate on probe-start and pulse-start

21 ballasts. I guess this is perhaps a question

22 for manufacturers. Does the current test

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 70'

1 procedure give you enough guidance on how to

2 measure that lamp?

3 MR. BROOKMAN: Susan, please.

4 MS. ANDERSON: We haven't

5 discussed this, but if the reference ballast

6 is pulse-start ballast, you know, if that's

7 what the technology is. If that's the defined

8 reference ballast I would think the

9 measurements would be taken on the referenced

10 ballast.

11 MR. MYER: Michael Myer, are you

12 asking about the lamps that have a dual start

13 mechanism that can be either probe or pulse,

14 essentially like Philips AllStart Lamp, what

15 is the reference ballast there?

16 MR. MCGARAGHAN: Yes.

17 MR. MYER: And is that answer

18 you're saying, Susan?

19 MS. ANDERSON: Yes, I would think

20 that would be the logical thing. If the

21 reference ballast goes back to being in the

22 probe start technology, rather, that's where

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 71'

1 you would go. Whatever the technology is of

2 the reference ballast, because most of those

3 lamps are made, there are lamps that are made

4 to retrofit into probe start applications.

5 That's the primary one.

6 MR. MCGARAGHAN: Okay, so I don't

7 have an opinion at this point one way or

8 another how it should be. I just wanted to

9 make sure that the standard, as it's written,

10 does have enough clarity and it sounds like at

11 least Osram's got an opinion on how they would

12 interpret it. If that's not how DOE intended

13 it to be interpreted then my comment would be

14 to address that in further detail.

15 MR. BROOKMAN: So would NEMA

16 intend to address this point in its written

17 comments? Keith.

18 MR. COOK: Yes, Keith Cook. Yes,

19 we can address that. I think what we're

20 finding is this is a very complex subject.

21 We've got the self-ballasted, we have the

22 AllStart type lamps. We have the HID, we have

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 72'

1 probe start. It almost ends up being a

2 specific test for each different type of lamp,

3 which I don't think we're wanting to get into.

4 But I'm not sure how we're going to address

5 but we will add some comments to this.

6 MR. BROOKMAN: Okay, thank you.

7 Mike McGaraghan.

8 MR. MCGARAGHAN: Mike McGaraghan.

9 One final question on ballasts. In the

10 reference in the ANSI standard, I think it's

11 C85, I don't have it in front of me. But the

12 one that has all the reference ballast

13 characteristics in it.

14 I notice there are different

15 reference ballast characteristics based on

16 lamp orientation, whether it's vertical, base17 up or horizontal. It seemed odd to me but I

18 wanted to bring it up and if that is industry

19 standard and that makes sense to the

20 manufacturers then I won't push it.

21 MS. ANDERSON: Now there are lamps

22 that are only designed for base-up operation.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 73'

1 Some that are only base-down or some that can

2 be in either of those orientations. And then

3 there are lamps that are exclusively designed

4 for horizontal operation, plus or minus 15

5 degrees of the horizontal.

6 MR. MYER: And each of those is

7 deserving of different reference ballast

8 operating characteristics?

9 MS. ANDERSON: No.

10 MR. COOK: No.

11 MS. ANDERSON: Susan Callahan, can

12 you comment on that?

13 MS. CALLAHAN: I'm looking at the

14 ANSI standard for metal halide lamps and I'm

15 not seeing different reference ballast

16 characteristics depending on orientation in

17 this document.

18 MR. BROOKMAN: I see Heidi shaking

19 her head. Do you want to comment for the

20 record, Heidi? No. Okay. Susan, go ahead.

21 MS. ANDERSON: No, I mean when

22 you're actually doing the testing of the lamp

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 74'

1 it would be tested in its designed position.

2 MR. COOK: The lamp is designed

3 for a wattage, it doesn't know what the

4 orientation is.

5 MS. ANDERSON: -- to the lamp not

6 the ballast.

7 MS. CALLAHAN: Okay, there are

8 different ranges for lamp voltage and current

9 depending on the orientation of the lamp. But

10 they would be tested using the same reference

11 ballast characteristics. So once installed

12 characteristics don't change.

13 MR. MCGARAGHAN: Great, I'll

14 follow up perhaps with you, Susan, offline and

15 if I can just send you this table and you can

16 help me understand.

17 MS. CALLAHAN: Okay, thank you.

18 MR. BROOKMAN: Okay, final

19 comments on this?

20 MR. HITCHCOCK: This is Bill

21 Hitchcock from Philips with a question.

22 MR. BROOKMAN: We hear you, keep

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 75'

1 going. Yes.

2 MR. HITCHCOCK: I think there may

3 be some confusion here. I do not believe that

4 C78.389 carries the characteristic for the

5 reference ballast. It's C78.43, the lamp

6 standard, that defines the characteristics.

7 And therefore, you've only got characteristics

8 for reference ballast on lamps that are

9 standardized.

10 MR. MCGARAGHAN: Can you say the

11 number there again, C78.43?

12 MR. HITCHCOCK: C78.43.

13 MR. MCGARAGHAN: I was actually

14 referencing C82.5, so maybe I was in the wrong

15 place to start with.

16 MR. HITCHCOCK: I believe C82.5

17 has the characteristic, the rules for how to

18 determine a reference ballast. But I do not

19 believe it lists the actual values for the

20 specific lamps.

21 MR. BROOKMAN: Okay, thank you.

22 Any other questions or comments related to

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 76'

1 reference balance ballast issues?

2 MR. STEELE: Continuing on with

3 our quest to minimize test measurement result

4 error, one potential source of error is not

5 using correct measurement equipment. So here

6 we're showing some of the instrumentation

7 requirements pulled from ANSI C78.389 for the

8 electrical measurements. And LM-51 for the

9 photometry.

10 We're dealing with AC here, hence

11 there's a possible frequency range and

12 harmonics therein, so therefore there is a

13 frequency range accuracy requirement in any of

14 the measurement equipment there.

15 Any measurement equipment that is

16 put in circuit during the test measurement

17 should not affect the lamp operation. That

18 being it should not disturb the lamp's

19 characteristic voltage and current.

20 Moving on to light output and

21 color measurement, we're requiring a V-lambda

22 spectral response and photometer that is with

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 77'

1 any photometric measurement we scale to a

2 human visual response.

3 And for a chromaticity, CCT and

4 CRI we also mention spectral radiometry, which

5 is considered by industry a more precise

6 method for determining those values.

7 So that brings us to Issue Number

8 6 on the proposed instrumentation

9 specifications.

10 MR. BROOKMAN: Joe.

11 MR. HOWLEY: NEMA discussed this

12 and had one comment. And that was that we

13 believe more specificity can be provided on

14 the integrating sphere diameter in terms of

15 that last requirement, or comment. There are

16 some recommendations in CIE and we'll provide

17 more of that in our written comments.

18 MR. STEELE: Thank you for that.

19 MR. BROOKMAN: Other comments

20 related to Issue Box 6, on proposed

21 instrumentation specifications and

22 appropriateness of ANSI C78.389 and LM-51?

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 78'

1 Okay.

2 MR. STEELE: Now we're going to

3 discuss the sampling method for these HID lamp

4 test procedures. For each HID lamp basic

5 model we're requiring that the lamp

6 characteristics be representative of a

7 manufacturer's production output.

8 So therefore we need a sampling

9 plan to determine product process variability

10 and DOE is proposing to adopt the sampling

11 plan from another lighting equipment rule

12 that's already in the Code of Federal

13 Regulations in Section 429.27.

14 This is actually from the GSFL

15 Rule and it is, sample test units are obtained

16 via a random selection. Sample plan is over a

17 12-month period and we're requiring a minimum

18 of 21 samples hopefully spread evenly over the

19 12-month period. I believe there is a minimum

20 seven-month period available also if

21 production does not run the full 12 months.

22 Then, with those sample test

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 79'

1 group, you then go ahead and do the test

2 procedures and determine the lamp

3 characteristic measurements and take the mean

4 of those measurements. This brings us to

5 Issue Box Number 7, regarding the proposed

6 sampling method.

7 MR. BROOKMAN: Alex.

8 MR. BOESENBERG: Alex Boesenberg

9 of NEMA. You mentioned the GSFL Standard. We

10 disagreed with the statistical measurement and

11 the approach at that time, we will disagree

12 with it again. And I will attempt to bring

13 more information to bear at this time.

14 We disagree, we talk about

15 inherent uncertainty but then misapply the

16 statistical T test. So we will submit some

17 more information to that, but the uncertainty

18 brings with it a certain requirement that you

19 allow a great degree of tolerance, or range of

20 tolerance. And we'll comment to that.

21 But there's one other portion,

22 besides just the statistical discussion

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 80'

1 itself, is that in Europe they have a ten

2 percent plus or minus in their reporting and

3 testing requirement. And as such any

4 manufacturer that sells to both markets would

5 be disadvantaged if they were testing to a

6 much tighter tolerance here in the U.S.,

7 because they'd have to potentially run two

8 tests.

9 We'll provide greater explanation

10 on that. It's very difficult for me to speak

11 about statistics. But, again, we disagree

12 with some of that approach.

13 MR. BROOKMAN: Alex, in addition

14 to commenting on what is proposed, will NEMA

15 propose an alternative?

16 MR. BOESENBERG: Yes, we will.

17 MR. BROOKMAN: Thank you. Tina.

18 DR. KAARSBERG: Alex, my

19 understanding is that NEMA disagreed with the

20 initial GSFL proposal, which had, I think, 20

21 samples. In the final version our intent

22 anyway was to agree with NEMA on that.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 81'

1 So I'm just stating that if we

2 don't agree with you in the final version it

3 would be helpful if you could explain why as

4 well I think that was October 4th when we had

5 that meeting when you talked about it.

6 MR. BOESENBERG: Yes, I remember

7 from that we talked about how 20 didn't make

8 any difference statistically from 21 due to

9 the requirement to get to 50 percent failure.

10 But we'll bear that in mind and I'll get a

11 greater explanation on that.

12 Also we will comment later on the

13 21 sample size and the 12-month sampling,

14 because these are very long-lived lamps once

15 you get to December and pull a lamp and begin

16 testing it it's a long time before you have

17 the results.

18 MR. BROOKMAN: Joe.

19 MR. HOWLEY: Yes, I'd just like to

20 add, our statistical expert is not here. But

21 the source of the concern really came out of

22 the CCE rule versus the GSFL rule. And it had

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 82'

1 to do with how the statistical test was being

2 applied to lamp samples. Our statistical

3 person believes that the T test is being very

4 inappropriately applied. And he's going to

5 provide some written comments on exactly how

6 he feels that this is being misapplied.

7 But it has an effect when you have

8 products that have fairly tight tolerances,

9 like incandescent and fluorescent, but it has

10 a much more severe effect of misinterpreting

11 this if you're applying it to HID lamps, which

12 need and have a much wider tolerance on things

13 like lumens and lumen maintenance and issues

14 like that.

15 So although we had a concern and

16 it wasn't addressed with the CCE we don't feel

17 in this particular case that we could afford

18 to ignore it. We simply cannot have the

19 statistical test and supply for these

20 particular lamps because of the tolerances

21 needed.

22 So we'll provide more written

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 83'

1 comments. We'll have him provide them because

2 he understands the statistical issues much

3 better than we do.

4 MR. BROOKMAN: Okay. Whoever is

5 coughing, if they could mute their phone that

6 would greatly be appreciated for those of us

7 in the room. Those of you that are joining us

8 online please mute your phones. We're going

9 to return to the slides and keep going.

10 MR. STEELE: Thank you for all the

11 comments and pending input, we look forward to

12 reviewing it. Now I would like to hand the

13 podium over to Heidi Steward who's going to

14 discuss the next issue.

15 MS. STEWARD: This is the musical

16 portion. All right, aging is just turning a

17 lamp on and letting it run for a specific

18 period of time to prepare it for testing and

19 use. Each lamp is aged only once. DOE

20 proposes all HID lamps be aged 100 hours in

21 the position it will be tested, base-up, base22 down or horizontal.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 84'

1 After aging a lamp must be warmed

2 up and measured to verify stabilization. Each

3 of the three types of lamps is physically

4 different and thus has different warm-up and

5 stabilization criteria.

6 As you can see they range in warm7 up time from 15 to 20 minutes for mercury

8 vapor all the way to six hours for metal

9 halide lamps. And stabilization criteria are

10 generally three successive measurements of

11 voltage and current across variable

12 measurement intervals and changes of values

13 depending on lamp type.

14 This is Issue 8. We invite

15 comments and data on the applicability of the

16 proposed 100 hour aging requirements and

17 stabilization methods.

18 MR. BROOKMAN: No comments? Joe,

19 what?

20 MR. HOWLEY: The only comment here

21 was that NEMA agrees with using the ANSI

22 C78.389.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 85'

1 MR. BROOKMAN: Thank you, that's

2 useful. Okay, Heidi.

3 MS. STEWARD: Depending on where a

4 lamp is aged or warmed up often it needs to be

5 moved. So transfer and re-stabilization

6 requirements are necessary. Again, lamps

7 differ physically so they have different

8 requirements.

9 The detailed lamp stabilization,

10 re-stabilization and lamp transfer

11 requirements for the various HID lamp types,

12 metal halide, high pressure sodium and mercury

13 vapor, are provided in C78.389. So our issue,

14 DOE has proposed lamp cool down and re15 stabilization methods for HID lamps and

16 invites comments.

17 MR. BROOKMAN: Susan.

18 MS. ANDERSON: In practice, I mean

19 once again, the NEMA companies have discussed

20 this and we all do the same thing. We

21 stabilize the lamps and then, without changing

22 their orientation or removing power from them,

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 86'

1 move them into the sphere and then make sure

2 they're stabilized within the sphere. And it

3 usually takes about 15 minutes within the

4 sphere.

5 We check the measurements, if not

6 stable we give them additional time. But we

7 have a very specific procedure that we all

8 agree that we use and we will give that to you

9 in detail in our written comments.

10 There is no cool down time because

11 we don't turn the lamps off before we put them

12 in the sphere. We keep power, keep the lamps

13 energized and move them into the sphere.

14 MS. STEWARD: Lamp orientation is

15 the recommended burn position. Susan spoke

16 briefly about it earlier. Generally you have

17 base-up, base-down or horizontal. The

18 orientation for aging and stabilization must

19 be the same as that as for testing.

20 The physical changes can occur

21 during aging and stabilization. If the lamp

22 is turned before testing it can give you

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 87'

1 completely different testing results than if

2 the orientation were maintained.

3 So for consistency of measurement

4 DOE has proposed the requirements of ANSI

5 C78.389. Issue 10, we invite comments on this

6 lamp orientation requirements.

7 MR. BROOKMAN: I see a few heads

8 nodding from manufacturer representatives, so

9 would you state that, Susan, for the record,

10 please?

11 MS. ANDERSON: Yes, we agree.

12 MR. BROOKMAN: You agree with

13 that, okay. Thank you.

14 MS. STEWARD: As we discussed

15 briefly before, directional lamps require

16 different measurements to calculate beam

17 angle. Setup and measurement of directional

18 lamps are proposed to be done following ANSI

19 C78.379, which provides classification of beam

20 patterns and technical guidance pertaining to

21 directional lamp measurement and evaluation.

22 Issue 11, we invite comments on

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 88'

1 proposed setup and measurements standard

2 selection for directional lamps.

3 MR. BROOKMAN: Joe.

4 MR. HOWLEY: Again, in our

5 industry discussions we were concerned how

6 this may be applied and just note that

7 measuring the beam performance of directional

8 lamps increases the measurement variation if

9 you're using zonal lumens to set efficiency

10 limits.

11 So again, this would require a

12 higher statistical variation tolerance on

13 measurements if we head down that path. So

14 far we haven't had any standard yet that deals

15 with directional lamps in terms of taking into

16 account the zonal lumens.

17 So we're approaching a new area

18 here. I think it all has to be carefully

19 thought out as we look at standards. Thank

20 you.

21 MR. BROOKMAN: So is NEMA going to

22 do some additional work on this, Alex?

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 89'

1 MR. HOWLEY: I'll ask the members

2 to discuss it. We're not sure yet how much we

3 can provide other than just to say make it

4 wide.

5 MR. BROOKMAN: Michael Myer.

6 MR. HOWLEY: Plus or minus 100

7 percent.

8 MR. MYER: Just to clarify. The

9 comment is not in disagreement of the setup,

10 it is only in the possible calculation or

11 metrics derived from the setup, or from the --

12 MR. HOWLEY: That's right, we do

13 agree with ANSI C78.379 being applied here,

14 just how you apply it.

15 MR. MYER: Right, how it's applied

16 and how tight the tolerance is held when

17 you're talking about zonal lumens, which

18 provides a lot of tolerance issues.

19 MR. BROOKMAN: Okay, so that was

20 Alex followed by Joe. Thank you.

21 MR. MCGARAGHAN: Mike McGaraghan,

22 California IOUs. I think I missed a chance to

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 90'

1 comment two slides back on orientation. I

2 just wanted to ask about lamps marked as

3 universal. It looks like the proposal is to

4 test base-up, which is I understand how it's

5 always been done.

6 The question, I guess, for the

7 group is if there's ever been discussion about

8 the performance of universal lamps in other

9 positions besides base-up and whether it

10 should be measured or reported to the consumer

11 if there's a big variation.

12 I understand that often base-up is

13 the best performing position. So if some

14 lamps that maybe their performance drops off a

15 lot when you move to horizontal versus another

16 lamp where the performance doesn't drop off

17 much, is that an important thing to measure?

18 Is there some strategy to capture that either

19 in the test procedure or in the literature for

20 these products?

21 MR. BROOKMAN: Susan.

22 MS. ANDERSON: If you go to our

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 91'

1 literature, if it's a universal burning lamp,

2 or operating lamp. Shouldn't say burning. We

3 provide both the vertical and the horizontal

4 lumens. But, I mean, the main application for

5 these lamps are where they're used in things

6 like floodlights where they're always tilted

7 at an angle. So we do have to have some sort

8 of a lamp that's tolerant of the multitude of

9 many positions the lamps could be operated in.

10 You know, it's not like it's

11 going, you know, the most common application

12 is say a high bay fixture and it's base-up and

13 traditionally people do try to design the

14 luminaires based on base-up or base-down

15 because for those lamps they're most efficient

16 in vertical positions.

17 But, once again, there are some

18 fixtures, like flood lights, where you have to

19 aim them. So we have to have a lamp designed

20 that's tolerant of that. But the most common

21 application would be in the vertical position.

22 And as far as we, as a manufacturer, go we do

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 92'

1 publish both the vertical lumens and the

2 horizontal lumens.

3 MR. MCGARAGHAN: And apart from

4 publishing that in your literature would it be

5 appropriate to actually measure both in the

6 test procedure and consider standards in both

7 positions?

8 MS. ANDERSON: That would add

9 significant testing burden to us.

10 MR. MCGARAGHAN: But I thought you

11 already reported that?

12 MS. ANDERSON: We do measure it.

13 MR. HOWLEY: In terms of

14 standards, this is Joe again, we all think

15 that would be appropriate as the most common

16 position is the vertical position.

17 And in terms of testing and

18 meeting these standards, which already can be

19 quite onerous, it would add a very high level

20 of testing concerns to try to measure out all

21 these different angles that a few fixtures

22 might operate in. So no we wouldn't agree to

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 93'

1 having standards at all of these different

2 operating positions. The primary operating

3 position.

4 MR. BROOKMAN: Keith.

5 MR. COOK: Keith Cook with

6 Philips. Even though we may do the testing

7 today we don't do it necessarily through a

8 NVLAP approved facility. And the implication

9 here is that we are going to go to a NVLAP10 approved facility which significantly will add

11 cost.

12 And by having to do this on a

13 third party, with a lot of the smaller

14 manufacturers, you're significantly doubling

15 the costs by asking them to do it in multiple

16 orientations now. And there's a huge burden

17 associated with that which we're concerned

18 with.

19 MS. ANDERSON: And once again, the

20 primary application is the vertical

21 application. It's just these few applications

22 where you see flood lights, where the angle

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 94'

1 could be anything and you there's no way in

2 the world you could begin to test for all

3 those potential aiming angles.

4 MR. BROOKMAN: Okay, thank you,

5 Susan. Heidi.

6 MS. STEWARD: Thank you. On to

7 the aforementioned NVLAP. NVLAP is a National

8 Voluntary Laboratory Accreditation Program.

9 They accredit laboratories for many types of

10 testing, not just luminaire testing or lamp

11 testing.

12 The DOE proposes testing for HID

13 lamps test procedure be done at independent

14 test labs or manufacturer/importer testing

15 labs that have been accredited by NVLAP or

16 another organization recognized by NVLAP.

17 So on Issue 12 we request comment

18 on the proposal to require NVLAP accredited or

19 equivalent labs for testing, similar as DOE

20 required in the GSFL test procedure.

21 MR. BROOKMAN: Keith.

22 MR. COOK: Keith Cook with

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 95'

1 Philips. I've already alluded to this a

2 little bit, but we're a little confused, first

3 off, by the wording of this thing. First off,

4 "by an accrediting organization recognized by

5 NVLAP." NVLAP does not recognize any other

6 accrediting bodies, they just don't do that.

7 MS. STEWARD: They do for other

8 types of lighting. They do for solid-state

9 lighting.

10 MS. ANDERSON: Don't.

11 MR. COOK: No, they don't. It's

12 through NIST that you get the accreditation.

13 MS. STEWARD: Okay.

14 MR. MYER: We'll research that

15 aspect, thank you for pointing that out.

16 MR. COOK: But even then, the

17 other potential implication of this wording is

18 going to certification bodies. And we had

19 really cautioned DOE that that may be a

20 mistake.

21 EPA has done that through the

22 EnergyStar and that has not worked out

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 96'

1 extremely well. It's led to a lot of chaos

2 because of different interpretations of

3 testing standards and testing setups and

4 specifications.

5 And as a result it's caused a lot

6 of delay of new product introductions and

7 listings of new products on their websites.

8 It has become a major fiasco. We'll include a

9 lot of comments on this, but we do caution the

10 DOE about going down this path.

11 MR. BROOKMAN: The principal

12 comment relates to different or multiple

13 certification bodies, correct?

14 MR. COOK: Correct.

15 MR. BROOKMAN: And so say what

16 you'd like to see have happen with NVLAP in

17 your comments, right?

18 MR. COOK: Will do.

19 MR. BROOKMAN: Okay. Other

20 comments on Issue Box 12?

21 DR. DAUBACH: This is Ron Daubach

22 Osram Sylvania. I believe that the DOE also

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 97'

1 proposes that manufacturers’ accredited

2 laboratories can also supply the test results.

3 That is still DOE's position?

4 MR. BROOKMAN: Michael Myer.

5 MR. MYER: At this time that is

6 what is proposed, it would be an accredited

7 laboratory.

8 DR. DAUBACH: Okay.

9 MR. BROOKMAN: Okay, Ron, thank

10 you. All of you that are joining us online

11 you're doing a great job of keeping those

12 phones muted, thanks for doing that. Alex.

13 MR. BOESENBERG: This is Alex

14 Boesenberg from NEMA. Specific to your

15 question of whether or not additional or

16 alternative requirements for testing labs

17 should be considered, we suggest that we

18 refrain from adding any additional

19 requirements due to the cost.

20 MR. BROOKMAN: Other comments on

21 Issue 12 before we move on? Okay.

22 MS. STEWARD: So we can move on to

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 98'

1 test measurements and calculations with

2 Lindsay Steele.

3 MR. STEELE: Almost there. This

4 slide shows the logical progression of the

5 proposed HID lamp test procedures. I have a

6 nice start/finish arrow to kind of show you

7 the direction that we're heading in here.

8 First off we start with an initial

9 operation of 100 hours on the lamps burn, call

10 that the lamp aging or sometimes referred to

11 as seasoning. There is no exception to this

12 rule, per the standard.

13 Then the next thing that would

14 happen is the lamps would be stabilized before

15 any kinds of measurements are done. And then

16 when we move into the measurement phase of the

17 procedures, taking the electrical and

18 photometric characteristics.

19 Once you have established those

20 measurements you would then repeat for each

21 lamp in the sample test group, and then one

22 would go ahead and calculate the lamp efficacy

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 99'

1 and lumens per watts and take the mean values

2 and generate a report with the group test

3 results and statistics.

4 The characteristics that we would

5 like to see in the report would be efficacy,

6 CRI, CCT, lumen maintenance, obviously, and

7 beam angle. Again we'll remind you that DOE

8 is considering using the color values to

9 delineate the equipment classes of the HID

10 lamp in the energy conservation standards that

11 are coming up.

12 Apologies for having to kind of

13 switch slides here. But that brings us to

14 Issue Box Number 13 where we're inviting

15 comment on the suitability of the measurement

16 and calculation procedures of HID lamps.

17 MR. BROOKMAN: Let's flip back to

18 the previous slide.

19 MR. STEELE: I will do.

20 MR. BROOKMAN: Comments we know

21 are on this slide, Slide 38. Joe.

22 MR. HOWLEY: This comment is

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 100'

1 basically kind of summing up what we've been

2 talking about today and this slide takes us

3 through all the different testing and

4 different outputs that we'd be looking at.

5 And, as we've mentioned this

6 morning, concerns about tolerances, kind of,

7 all the way through this process. Needing the

8 proper tolerances on the lumen output. If

9 we're adding a zonal lumen distribution,

10 calculation tolerances within that area.

11 If we're measuring CCT or CRI,

12 again we talked about tolerances there and

13 appreciate that DOE is looking for what we

14 might suggest in these areas in terms of

15 tolerances.

16 And then finally, the labs

17 themselves we've noticed even in doing round

18 robin testing in labs there could be a

19 tolerance of four percent or more just across

20 the individual labs that may be trying to do

21 compliance or certification testing. This

22 would have to be taken into account as well.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 101'

1 Yes, NVLAB labs.

2 MR. BOESENBERG: That's not our

3 number, NVLAP has tested effectiveness or

4 repeatability among different labs and they

5 give a four percent margin from one lab to the

6 next.

7 MR. BROOKMAN: For the NVLAP8 certified labs, within that identified group,

9 four percent?

10 MR. BOESENBERG: Right, test the

11 same gear from one lab to the next. And they

12

--

13 (Off microphone comments.)

14 MS. ANDERSON: It's four percent

15 or more. Four percent or more depending on

16 the lamp technology. And HID lamps being the

17 most variable.

18 MR. BROOKMAN: Interesting.

19 MR. BOESENBERG: It's my

20 understanding that's for lamps, yes. And, if

21 I may, this is Alex Boesenberg again. It's

22 not specific to the test procedure standard,

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 102'

1 but for the record we would like to raise the

2 concern that in terms of certification,

3 compliance and enforcement, since one day this

4 will all end up in that arena, because of the

5 lifetime of HID lamps, and I alluded to this

6 earlier, testing to the 40 or 50 percent rated

7 life-point, annual testing is not feasible,

8 due to the, first, the annual sampling itself.

9 And then the fact that these last so stinking

10 long. You can't do it every year.

11 MR. MYER: Michael Myer. I just

12 want to follow-up on the tolerance comment Joe

13 had. I had two values there that I didn't

14 hear and I just wanted to ask about those

15 tolerances. Power, I assume, is there a lot

16 of tolerance there? And you don't have to

17 answer now, it can be in the comment. I just

18 wanted to put that one out there.

19 And you've also used the term

20 zonal lumens a couple of times and I just

21 wanted to also interject it with intensity,

22 candelas, again, is there a lot of assumed

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 103'

1 tolerance in intensity at a given angle?

2 MR. HOWLEY: Yes, there can be

3 because of the, just shape of the reflector or

4 tolerances within the reflector. How well

5 that's aimed within an HID arc source.

6 There's tolerances within the center beam

7 candlepower as well.

8 MR. BROOKMAN: Okay, Michael, yes.

9 MR. MYER: That addressed the

10 question I was asking, thank you.

11 MR. BROOKMAN: Thank you. Okay. So,

12 Joanna Mauer.

13 MS. MAUER: Just a quick question.

14 Would lumens per watt be the metric for

15 directional lamps as well as omnidirectional

16 lamps?

17 MR. BROOKMAN: Joe Howley.

18 MR. HOWLEY: I'm just answering in

19 that it has been so far, in the incandescent

20 reflector lamps, we've had simply a lumen per

21 watt metric on those. We have discussed

22 whether or not it makes sense to look at the

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 104'

1 directional nature of the center beam

2 candlepower in these other rulemakings, but to

3 date we haven't gone down that path. This is

4 the first rule where we've actually proposed

5 looking at this path.

6 So it's something that on one hand

7 makes sense. On the other hand introduces a

8 lot of tolerance concerns.

9 MR. MYER: Following up on Joe.

10 This is Michael Myer. Again, no metrics have

11 been proposed, just at some point after lumens

12 you would need some aspect of intensity and

13 that's all we're proposing to measure.

14 And these are actually following

15 comments from NEMA from the high intensity

16 discharge determination where they said look

17 at something else. But it was not stated, as

18 Joe has identified, there's some issues that

19 have to be addressed before you could set a

20 metric. But we are not proposing any metrics,

21 just test the next logical thing.

22 MR. BROOKMAN: Tina Kaarsberg.

1 DR. KAARSBERG: I don't know if we

2 have this data, but it would be interesting to

3 just see the data on how many of the lamps are

4 directional versus the fixtures. My

5 understanding is that there are not that many

6 directional lamps, so for a lamp standard it

7 may not be an issue. But that most HID

8 fixtures are directional fixtures. So any

9 data you all could provide, or insights on how

10 they're used would be very helpful to us.

11 MR. HOWLEY: That is a good

12 comment. When you look at the whole world of

13 HID lamps the fast majority of them are

14 omnidirectional. There is just a very small

15 subset of HID lamps that are actually in a

16 reflector shape. So it also would be worth

17 considering how much energy and time might be

18 directed at directional HID lamps.

19 We know there's another rulemaking

20 being proposed for reflector lamps, which is

21 all directional, so that might make more sense

22 to venture down this path versus an HID

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 106'

1 rulemaking where such a small percentage of

2 the lamps are indeed directional lamps. Thank

3 you.

4 MR. BROOKMAN: Mike McGaraghan.

5 MR. MCGARAGHAN: Mike McGaraghan,

6 California IOUs. We would definitely support

7 any effort that goes into looking for a

8 directional metric and agree with what Joe

9 just said that the incandescent reflector lamp

10 rulemaking might be the more appropriate

11 place. But I also think that they probably

12 could be the same metric used for both HID and

13 incandescent reflector lamps. So maybe it's a

14 kill two birds with one stone situation.

15 MR. BROOKMAN: Okay. So any

16 additional comments on this sequence of test

17 measurement and calculations that's shown on

18 Slide 38? Mike.

19 MR. MCGARAGHAN: Mike again. I

20 wanted to follow up on Alex's comment about

21 color. Alex commented that NEMA doesn't

22 support using color to establish product

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 107'

1 classes.

2 I want to clarify, I guess, that

3 the test procedure rulemaking isn't going to

4 answer that question. That that decision

5 would be made later in the rulemaking itself.

6 And that, in the meantime, NEMA is okay with

7 the proposed test methods for measuring color.

8 Are both of those, I guess first a question

9 to DOE and then a follow-up to NEMA.

10 MR. BROOKMAN: Michael Myer.

11 MR. MYER: Yes, all the test

12 procedure does is just says test color quality

13 and it doesn't set any requirements, doesn't

14 delineate, it just says test and then you do

15 something with it.

16 MR. BROOKMAN: Yes, Alex.

17 MR. BOESENBERG: And this is Alex

18 Boesenberg. We have no argument with those

19 ANSI standards, no.

20 MR. MCGARAGHAN: Thank you.

21 MR. BROOKMAN: So as I think

22 that's the last issue box and this is the

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 108'

1 final slide, substantive slide. So I'm

2 turning it back then to Tina. Yes?

3 DR. KAARSBERG: Well, I have a

4 request and if you want to comment as well

5 that would be great.

6 MR. BROOKMAN: You should offer an

7 opportunity for closing remarks.

8 DR. KAARSBERG: Right, right. But

9 specifically on Mike McGaraghan's comment that

10 it would be good if there were some kind of

11 directional metric that it would be the same

12 for incandescent reflector lamps and HID

13 reflector lamps.

14 I'd just be curious if you all do

15 have any comments on that, on his comment, I'd

16 be interested in hearing your comments as

17 well.

18 And in general, closing remarks.

19 This is, I guess, where we ask everyone to

20 kind of sum up, surmise what they're doing. I

21 think on DOE's part we have some homework to

22 do. A lot of your excellent questions we

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 109'

1 couldn't answer because we haven't really

2 gotten there yet in terms of other work we're

3 doing on the standard and such.

4 But I really appreciate everyone's

5 comments. And they will all be reflected in

6 the next round of the test procedure. And I

7 really strongly encourage you to submit

8 comments by the 28th. And, at this point, I

9 guess we're going to go around the room and

10 see what people want to say to the proposed

11 test procedures.

12 MR. BROOKMAN: Any final comments

13 or additional comments here at the end?

14 Keith.

15 MR. COOK: Keith Cook with

16 Philips. One additional comment is we'd like

17 maybe a closer look at the cost estimates that

18 were put into this. The --

19 MR. BROOKMAN: Keith, you need to

20 get closer to that microphone, thank you.

21 MR. COOK: The energy consumption

22 for the life testing to determine 40 percent

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 110'

1 and even the 70 percent maintenance, [we

2 estimate] that actually will exceed $200 per

3 individual lamp. And if you have 21 samples

4 per year then that's going to be over $4,200

5 right there. We actually sent it out to find

6 out what a third party would cost and they

7 came back considerably higher than even that.

8 Also the references made regarding

9 similarity between incandescent life testing

10 and HID lamp life are way overstated.

11 And last, but not least, assuming

12 the entire catalogue is incorporated as

13 different basic models, we're seeing as many

14 as 200 basic models then, per manufacturer.

15 And that would require 23 million kilowatt

16 hours of electricity annually to do the

17 testing, which ends up being over $2.3

18 million. So we believe that these cost

19 estimates need to be reviewed more closely.

20 MR. BROOKMAN: Thank you. Alex.

21 MR. BOESENBERG: Alex Boesenberg,

22 NEMA. To amplify that, so that is very

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 111'

1 pertinent both to the discussions of sample

2 size and especially to the definition of a

3 basic model, obviously.

4 And then one other comment I

5 wanted to make to sort of sum up on the

6 discussions we've had through the course of

7 today's meeting about where a specific

8 standard may not yet exist in terms of a

9 procedure. And we've said more than once the

10 general accepted industry practice is X, Y, Z.

11 I would like to point out, it's

12 sort of moot, or it's common sense, but the

13 more that we stick to the established

14 procedures and tests, whether by a specific

15 reference or by what we in the industry agree

16 is the general accepted industry practice, the

17 more we stick to that then easier it is to

18 implement the future standard because we don't

19 have to change what we've been doing.

20 In particular, as to my previous

21 comment about testing to 40 and 50 percent of

22 rated life, if one of the variables is

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 112'

1 something that involves statistical sampling

2 if we measure to points that we have already

3 done in the past therefore we have that data

4 already resident, the sooner and easier we can

5 supply the answer to whatever that piece might

6 be.

7 So sticking to the way we've done

8 it and the procedures we already have and

9 already, in a sense, paid for and set up the

10 facilities for at the different companies or

11 third party test labs means that we minimize

12 the burden to the industry and you maximize

13 the continued availability of product and you

14 minimize time to market for new products.

15 MR. BROOKMAN: Thank you. Joe.

16 MR. HOWLEY: Just as chairman of

17 the NEMA lamp section we appreciate the

18 opportunity to provide our comments today and

19 we'll follow up with written comments as well.

20 Thank you.

21 MR. BROOKMAN: Thank you.

22 Additional comments? Mike. Oh, I'm sorry,

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 113'

1 Susan, please.

2 MS. ANDERSON: I actually have a

3 question. Since there are so many open

4 issues, when you look at the schedule there's

5 not going to be an opportunity for another

6 comment period beyond the one that is due

7 February 28th.

8 Is it possible that there should

9 be another publication of proposals based on

10 the feedback that you get and the research

11 that you do, and then have another opportunity

12 for the interested parties to comment?

13 MR. BROOKMAN: Betsy.

14 MS. KOHL: We can take a look at

15 that.

16 DR. KAARSBERG: And a lot of your

17 comments overlap with the standard and there

18 will startto be opportunities for comment on

19 the standard as well.

20 MR. BROOKMAN: Mike.

21 MR. MCGARAGHAN: Mike McGaraghan,

22 California IOUs. A few questions. First,

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 114'

1 dimming lamps didn't come up at all today and

2 that may be because it's more a factor of the

3 ballast and not the lamp itself, maybe

4 industry can confirm.

5 But the question here is are there

6 any characteristics of lamps that are designed

7 to operate on dimming systems that would

8 impact the way they're tested or the way they

9 perform?

10 MS. ANDERSON: We don't have lamps

11 dedicated for dimming.

12 MR. MCGARAGHAN: Okay.

13 MR. BROOKMAN: That was Susan.

14 Thank you.

15 MR. MCGARAGHAN: So you can put

16 any lamp as long as it's designed to operate

17 with a dimming ballast?

18 MS. ANDERSON: So long as the lamp

19 and ballast are compatible.

20 MR. MCGARAGHAN: Okay. The other

21 question I wanted to ask is, there had been a

22 lot of discussion about measurement at 40

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 115'

1 percent or 50 percent of rated life. If the

2 implication now that DOE is considering a

3 standard level at 40 percent or 50 percent of

4 life?

5 MR. MYER: At this time there is

6 no standard. Just what we, what the

7 Department, would consider testing. There's

8 already precedent for CFLs and testing lumen

9 maintenance and I think most manufacturers and

10 everyone agree that while a certain HID lamp

11 might start off at economical value of 100

12 lumens per watt, over the course of the long

13 life that Alex is referring of 24,000 hours it

14 has not remained at that value. And we all

15 know this and it's a fact of the technology

16 and so that the efficacy is changed at some

17 point and it would be helpful to get a sense

18 of what that is. Maybe to set a standard, but

19 at this point it's just testing.

20 MR. BROOKMAN: That was Michael

21 Myer. Mike McGaraghan.

22 MR. MCGARAGHAN: Okay. I guess I

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 116'

1 didn't follow, what else might you do with

2 that information? If it doesn't end up as

3 part of the standard.

4 MR. MYER: Continue to do

5 research.

6 MR. MCGARAGHAN: Last question for

7 me is if DOE can provide any insight as to

8 this upcoming schedule for this rulemaking and

9 specifically rulemaking stages is the plan is

10 to start with a framework as is the usual

11 practice, or because of all the research that

12 went into the determination stage, any

13 elements of the HID rulemaking might get

14 skipped. And at what timeframe that will

15 happen.

16 DR. KAARSBERG: We can't really

17 comment on that. We are working, we're not

18 not working on it. But we can't really

19 comment on that right now.

20 MR. BROOKMAN: Thank you, Tina.

21 Mike, okay? Okay. Additional comments here

22 as we move towards closing? Michael Myer.

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 117'

1 MR. MYER: I just had a follow-up

2 note on from what Keith said. When you said

3 the catalog 200 basic models, was SKU, product

4 number, just so we could start looking at the

5 cost implications.

6 MR. COOK: I was trying to look at

7 logical groupings.

8 MR. MYER: Okay, I was just trying

9 to get a sense of how you -- Thank you.

10 MS. ANDERSON: It was based on ten

11 cents a kilowatt hour.

12 MR. BROOKMAN: Thanks, Susan. So

13 any additional comments here? I think we've

14 covered it at this point then. I'm going to

15 hand out, the Department makes a photocopy of

16 the business cards of attendees, I'll hand

17 that out to pass around. And also the

18 evaluation form.

19 And from my part I think we had a

20 very constructive meeting. Thanks to all of

21 you for being so knowledgeable and

22 forthcoming. Back to Tina.

Neal R. Gross & Co., Inc.'

1 DR. KAARSBERG: And thank you for

2 being you. Just one other thing, this is

3 pretty much everything but don't forget to

4 write. And up here on the screen is all the

5 various numbers and websites and names. And

6 don't forget Tuesday, February 28th, 2012, be

7 there, aloha, or before. Before is nice as

8 well.

9 And just one final note, some of

10 you cc me when you send in your comments and I

11 really appreciate that and it's great, but

12 there's no need to because I do eventually get

13 it. I mean get it pretty quickly. But you're

14 welcome to do that if you wish.

15 MR. BROOKMAN: Simone reminds me

16 that we wanted to provide the opportunity for

17 those that are joining us on the web to make

18 additional comments or summary comments,

19 perhaps.

20 DR. KAARSBERG: How could we

21 forget the web people?

22 MR. BROOKMAN: We didn't forget

Neal R. Gross & Co., Inc.'

### Page 119'

1 them, they just weren't here in the room.

2 DR. KAARSBERG: Okay so I would

3 like to invite the web participants to make

4 any closing remarks that they would like to

5 make. And, thank you.

6 (Off microphone comments.)

7 MR. BROOKMAN: So then final

8 comments from those that are joining us via

9 the web. Okay, so I'll just echo Tina's

10 comments to say thank you for joining us --

11 DR. DAUBACH: Hello, this is Ron

12 Daubach.

13 MR. BROOKMAN: Yes. Ron, go.

14 DR. DAUBACH: Yes, just a quick

15 question. Will DOE be providing specifics on

16 what data and how it will be reported?

17 MR. BROOKMAN: What data and how

18 it will be reported?

19 DR. DAUBACH: Yes, the last slide

20 indicated that group data was to be

21 calculated. Is only the group data to be

22 reported, for example, and which specific

Neal R. Gross & Co., Inc.'

202-234-4433'

### Page 120'

1 parameters will be reported? Or is that part

2 of the rulemaking?

3 DR. KAARSBERG: Oh, yes, the group

4 data. It will be for entire test sample

5 groups.

6 MR. BROOKMAN: Tina.

7 DR. KAARSBERG: Yes, this was an

8 just an illustration of how this would work.

9 This wasn't the exact requirement.It was to

10 just give you an idea of the sequence. And

11 this was just our best guess of how it might

12 happen just to illustrate, you know, how the

13 pieces all fit together. I mean, we can't

14 tell you what exactly the group is and what

15 you're testing and how you do the statistics

16 until you have a standard.

17 And then also we have to develop

18 the appropriate compliance guidance for that.

19 So I apologize for any confusion on that.

20 But that was just supposed to be an

21 illustration of how it might happen. I hope

22 that helps.

1 DR. DAUBACH: Thank you.

2 MR. BROOKMAN: Any additional

3 comments?

4 MR. ELLIS: This is Dave Ellis at

5 Intertek. I was concerned about the versions

6 of LM-51 and LM-47. They are both more than

7 ten years old. IES policy is to discontinue

8 them, take them off the market. A new version

9 of LM-47 is out and a new version of LM-51

10 will be out probably third quarter of this

11 year. Will these be replaced in the final

12 rule?

13 MR. BROOKMAN: Michael.

14 MR. MYER: We'll compare the two

15 documents. And obviously if the IES rescinds

16 a document because of its age we would like to

17 be with the most current unless there's some

18 major change that requires additional review.

19 MR. BROOKMAN: Thanks for the

20 comment. Okay so then I think we've now

21 completed the meeting. Thanks to all of you,

22 safe travels. And we'll see you next time.
