## 10-1 CHAPTER 10. SHIPMENTS ANALYSIS

10.1 INTRODUCTION

Lamp shipment estimates are key inputs to the national energy savings (NES) and net

present value (NPV) calculations. Shipments are also a necessary input to the manufacturer

impact analysis (MIA), which the U.S. Departme nt of Energy (DOE) conducts for its Notices of

Proposed Rulemaking (NOPRs). This chapter describes DOE’s methodology for projecting

annual shipments and presents in itial inputs and results for ge neral service fluorescent lamps

(GSFL) and incandescent reflector lamps (IRL)

In the shipments analysis, DOE develops a base case shipment forecast for each lamp

type to depict what would happen to energy use and consumer costs for the purchase and

operation of lamps in the absence of new or revi sed Federal energy conservation standards. In

determining the base case, DOE considers histor ical shipments, emerging technologies, the mix

of efficacies sold in the absence of any new or revised standards, and how that mix might change

over time. To evaluate the impacts of standard s on GSFL and IRL, collectively referred to in

this rulemaking as the “two cat egories of lamps,” DOE compares the base case projection with

forecasts of what could happen if DOE promul gates standards (the standards-case). DOE

considers multiple shipments scenarios to charac terize both the base case and standards-case

shipments. To determine the cumulative NES and NPV of standards, DOE compares forecasted

shipments of a base case to a standards-case over the NIA analysis period, 2012 to 2042.

The shipments model and the national impact s model are integrated into single Microsoft

Excel ® 

## spreadsheets for GSFL and IRL. The two sp readsheets are accessible on the Internet at

http://www.eere.energy.gov/build ings/appliance_standards/ . Appendix 11A discusses how to

access the spreadsheets and provides basic instru ctions for using them. This TSD chapter

explains the shipments models. Section 10.2 presents the shipme nts model methodology for

GSFL and IRL; section 10.3 describes the data inputs, histori cal shipments, base case scenarios

and shipments forecasts; section 10.4 discusses the impacts of st andards on the mix of lamp

designs and lamp-and-ballast designs; and section 10.5 presents the shipments results for the

different trial standard levels (TSLs).

10.2 SHIPMENTS MODEL METHODOLOGY

In this NOPR, DOE develops separate shipment models for GSFL and IRL. In general, to

forecast shipments for these two categories of lamp s, DOE followed a four-step process. First,

DOE used 2001-to-2005 historical shipment da ta from the National Electrical Manufacturers

Association (NEMA) to estimat e the total historical shipme nts (i.e., NEMA member and nonNEMA member shipments) of each lamp type anal yzed, except for 4-foot T5 MiniBP standard

output and high output lamps, as explained in section 10.3.2.2

. 1 

## Second, DOE calculated an

installed stock of lamps for each lamp type in 20 05, based on the average service lifetime of each

lamp type. Third, by modeling lamp purchasing events, such as lamp replacement and new

## 10-2 construction, and applying growth rate, replacem ent rate, and emerging technologies penetration

rate assumptions, DOE developed annual shipme nt projections from 2006 to 2042. DOE also

calibrated its shipments model to reflect conf idential shipment data provided by NEMA for 2006

and 2007. Finally, because the shipments of lamp designs and lamp-and-ballast designs (for

GSFL) often depend on their proper ties (e.g., ballast factor, efficacy, etc.), DOE developed base

case and standards case market-share matrices as another model input. The market-share

matrices characterize the efficacy, power rating, li ght output, and lifetime of the lamp and lampand-ballast designs. The matrices input the pe rcentage market share of each design into the

shipment model. DOE used these market-share matrices to forecast lamp stock and shipments,

taking into account each desi gn’s respective lifetime, and to determine the aggregate

characteristics of the market (e.g., average light output, efficacy, energy consumption, and power

rating).

10.2.1 General Service Fluorescent Lamps

10.2.1.1 Analyzed Product Classes, Market Sectors, and Market Segments

Consistent with observed market applicati ons, DOE forecast annual shipments for 4-foot

medium bipin lamps in the residential and commerc ial sectors, 8-foot single pin slimline and 4-

foot T5 MiniBP standard output (SO) lamps in the commercial sector, and 8-foot recessed

double contact high output (HO) and 4-foot T5 Mi niBP high output (HO) lamps in the industrial

sector. The shipments model analyzes all lamp types at TSLs which assign efficacy levels for

each product class. For further detail on the TS Ls, see chapter 9 of this technical support

document (TSD).

As it relates to 2-foot U-shaped lamps, DOE did not directly model their shipments

because of their relatively small shipments-based market share (approximately 4 percent). Given

the similarity of the 4-foot medium bipin and U- shaped product classes with regard to system

input power and historical shipment trends (which show a decrease in T12 lamps and an increase

in T8 lamps), DOE scaled the results from the 4- foot medium bipin product class to approximate

the NES and NPV of 2-foot U-shaped product cla ss. Because historical shipments of 4-foot

medium bipin lamps were 22 times that of 2-foot U-shaped lamps, DOE used this scaling factor

to approximate the energy savings and net pr esent value for 2-foot U-shaped lamps.

In addition, because GSFL of different correl ated color temperatures (CCTs) were not

segregated in the NEMA historical shipment data, DOE decided to analyze and forecast

shipments of each lamp type ( e.g., 4-foot medium bipin), and aggr egate lamps of low (less than

or equal to 4,500K) and high (greater than 4,500K) CCT. In each case, DOE uses a

representative product class (lam ps with CCT less than or equa l to 4,500K) to evaluate lamp

designs and believes that the national impacts will be similar for those product classes not

directly analyzed (lamps with CCT greater than 4,500K). By aggregating the low and high CCT

product classes, DOE assumes that there will be no significant migration of shipments or stock

between lamps of different CCTs.

## 10-3 In its GSFL shipment model, DOE considers specific market segments, or lamp purchase

events, to develop estimates of annual shipments. In the shipments model, DOE accounts for the

four market segments that corr espond to the lamp purchase events that DOE uses in the lifecycle cost (LCC) and payback period (PBP) analyses in Chapter 8. These include: lamp failure

(Event I), ballast failure (Event III), lamp-and-ballast system re trofit (Events II and IV), and new

construction (Event V). For each market segm ent, DOE makes certain assumptions about how

consumers are likely to purchase new lamps or lamp-and-ballast systems. DOE uses these

purchasing assumptions to develop the GSFL shipment forecasts.

10.2.1.2 Lamp Replacement

For those consumer purchases triggered by a lamp failure, DOE assumes that the

consumer will purchase a lamp identical to the one that has retired, if it is available. If in the

standards-case, the base case lamp design is not standards-compliant (and therefore unavailable

as a replacement option), then DOE assumes consumers will purchase a new lamp that is

compatible with the existing ballast. If no sta ndards-compliant lamps are compatible with the

consumer’s existing ballast, DOE models consum ers as retiring their lamp-and-ballast system

before the ballast’s end of life. The consumer’s purchase decision is then identical to that of a

lamp-and-ballast system retrofit.

DOE establishes the timing of lamp replacemen ts by tracking the shipments of lamps and

then predicting when lamps will retire based on their average service lifetime. Instead of using

each particular lamp design’s individual lifetim e, DOE uses the each lamp’s lifetime and the

estimated distribution of lamp shipments by lamp design to establish an average lifetime for each

lamp type. DOE then used the distribution of operating hours in each sector (discussed in the

Energy Use Characterization, chapter 6 of this TSD) to predict the probability of lamp failing in

any given year. Based on this probability, DOE calculates the quantity of lamp shipments

required for lamp replacement,

10.2.1.3 Lamp-and-Ballast System Replacement (Ballast Failure and System

Retrofit)

For consumer purchases triggere d by a ballast failure or lamp -and-ballast system retrofit,

DOE assumes that consumers will discard their ex isting lamps with the failed ballasts, even if

lamp life remains. Consumers will then purchase new lamp-and-ballast systems compatible with

their existing fixtures to repl ace their retired system.

Historical shipments and discus sions with industry experts indi cate that there are several

lamp-and-ballast replacement and retrofit trends within the GSFL market . DOE models these

trends in both the base case and standards-case shipment mo dels. For example, in the

commercial sector, DOE models a natural shift upon ballast retirement a nd replacement from 4-

foot T12 medium bipin magnetic ballasts (1- and 2-lamps per ballast systems) to 4-foot T8

medium bipin electronic ballast s (3-lamp per ballast systems). Specifically, DOE assumes 90

percent of commercial 4-foot T12 medium bipin magnetic systems are replaced with 4-foot T8

medium bipin systems and 10 percent are repl aced by 4-foot T12 me dium bipin electronic

## 10-4 systems. In the residential sector, DOE modeled a shift from 4-foot T12 magnetic ballasts to both

4-foot T12 magnetic systems and electronic systems in the base case, and, in the standards-case,

to 4-foot T8 systems as well. Specifically, in the residential base case, half of retiring 4-foot T12

magnetic systems are replaced by the same system, while the other half are replaced by 4-foot

T12 electronic systems. In the residentia l standards-case, as discussed in Section 10.4.1.3 and

shown in Table 10.56 , 4-foot T8 systems begin to penetrat e this market segment; they replace 25

percent, 35 percent, and 60 percen t of the retiring 4-foot T12 magnetic systems at TSL1, TSL2,

and TSL3, respectively (T12 lamps are non-compliant at TSL4 and TSL5 and therefore all T12

systems are replaced with T8 systems at TSL4 and TSL5). Half of remaining 4-foot T12

systems shipped at TSL1, TSL2, and TSL3 are ma gnetically ballasted and have are electronically

ballasted.

Similarly, in the commercial sector, DOE m odels a shift from 8-foot T12 single pin

slimline magnetic ballasts to 8-foot T8 and 8-foot T12 single pin slimline el ectronic ballasts, as

well as a system of two 4-foot T8 medium bipin electronic ballasts. Specifically, DOE assumes

80 percent of retired 8-foot T12 single pin ma gnetic systems are replaced by two 4-foot T8

medium bipin systems, 10 percent by 8-foot T8 single pin systems, and 10 percent by 8-foot T12

single pin electronic T12 systems.

Table 10.1 below presents the modeled lamp-and-ballast replacement trends. DOE also

modeled early (voluntary) retirement of lamp-and- ballast systems in the standards-case. Section

10.4.1.3 provides more details on the assumptions DOE makes regarding these retrofits.

## DOE establishes the timing of ballast repla cements in response to ballast failure by

tracking ballast shipments and then predicting when these ballasts are expected to retire based on

their service lifetime. DOE calcu lated average commercial and i ndustrial ballast service lifetime

by dividing the average ballast li fetime in hours (established in the LCC) by average operating

hours. The service life in the commercial a nd industrial sectors is 14 years and 10 years,

respectively. For the residential sector, DOE used a 15-year service life, consistent with

measured life studies.

10.2.1.4 Lamp-and-Ballast System New Purchase (Fixture Replacement,

Renovation, and New Construction)

Finally, for consumer purchases triggere d by fixture replacement, renovation, and new

construction, DOE assumes that consumers ma y purchase a variety of new lamp-and-ballast

systems to service their particular lumen demand. Because historical shipment data have shown

## 10-6 significant growth for only 4-foot T8 medium bipin and 4-foot T5 miniature bipin SO systems,

DOE models all purchases due to new constructi on in the commercial sector as being one of

these two lamp-and-ballast systems. In the resi dential sector, DOE mode ls only 4-foot medium

bipin systems for new construction. In the indus trial sector, confidentia l historical shipments

show a declining number of 8-foot recessed double contact HO lamps. Therefore, DOE assumes

that all system purchases due to new construction in the industrial sector are either 4-foot T5

miniature bipin HO systems (another rapidly gr owing market) or other emerging substitution

technologies (e.g., light emitting diodes).

DOE modeled 4-foot T5 MiniBP SO and HO shipment growth base d on a migration from

other product classes. DOE’s research indicated that shipment growth of 4-foot T5 miniature

bipin SO lamps is primarily driven by a migration from the 4-foot medium bipin market. As this

migration requires the purchase of a new fixture, to establish 4-foot miniature bipin T5 SO

shipments, DOE allotted a portion of the 4-foot medium bipin fixture replacement, renovation,

and new construction markets to 4-foot T5 mini ature bipin systems. To do this, DOE first

calculated the size of this potential market for ne w 4-foot T5 MiniBP SO systems in each year.

DOE then determined the portion of this market that would actually be serviced by 4-foot T5

MiniBP SO lamps by calculating the share that resulted in T5 shipments consistent with 2006

and 2007 historical data. DOE held this result ing percentage—approximately 12.5 percent of the

fixture replacement, renovation, and new constr uction market—constant throughout the analysis

period.

DOE developed 4-foot T5 MiniBP HO lamp shipments by modeling a migration from

two different lighting markets. Similar to 8-f oot recessed double contact HO systems, marketing

literature indicates a large porti on of 4-foot MiniBP T5 HO syst ems serve high-bay applications

due to their highly concentrated light output. Historical shipment data for 8-foot recessed double

contact HO lamps shows substant ial declines in 2006 and 2007, i ndicating T5 HO lamps may be

rapidly displacing them. In addi tion, DOE’s research indicated th at a significan t portion of 4-

foot T5 MiniBP HO growth can be attributed to their penetration into the high intensity

discharge (HID) lamp high-bay and low-bay markets. Therefore, to calculate the growth in 4-

foot MiniBP T5 HO lamp shipments, DOE assume d that these systems were penetrating both the

8-foot recessed double contact HO a nd HID markets. Similar to its analysis for T5 SO systems,

DOE established that the fixture replacement, renovation and new construction market segments

represent the available market for 4-foot Mini BP T5 HO systems. DOE obtained HID shipment

data from the HID determination, from which DO E calculated the total lumens servicing low bay

and high bay applications. Then, consistent with historical 4-foot T5 MiniBP HO and 8-foot

recessed double contact HO shipments, DOE a ssumed 4-foot T5 MiniBP HO lamps fully

penetrate the 8-foot recesse d double contact HO fixture repl acement, renovation, and new

construction market segments, as well as HID new construction and renovation market segments.

DOE bases its shipment estimates due to new construction based on EIA’s AEO2008,

which estimates year-to-year commercial floor space and residential build ing growth. Because

the AEO2008 takes into account future trends in economic growth, DOE was able to incorporate

forecasts of macroeconomic conditions in its growth forecasts. However, because the AEO does

not provide industrial floor space forecasts, DOE us ed historical MECS floor space values to

establish a growth rate for the industrial sector.

## 10-7 In addition to residential building growt h, DOE also modeled a trend toward an

increasing number of 4-foot medium bipin T8 and T12 lamps per home. DOE conducted an

analysis to estimate the average number of T8 and T12 lamps in homes between 2005 and 2042.

Using California data on these lamp s, which was broken out by home age, 2 

## DOE assumed that

the same number of T8 and T12 lamps per home would be installed in new homes as those

installed between 2001 and 2005, and that half of homes built before 2001 would be renovated

by 2042 to have the same number of T8 and T12 lamps as newly constructed homes. DOE

estimated that the average num ber of T8 and T12 per lamps home in 2005 was 4.5, and the

average number in 2042 will be 4.7. Combining this growth estimate of 4-foot medium bipin

lamps per home with AEO2008’s projected growth in the residential home stock yields an

average growth rate of 1 percent between 2006 a nd 2042 for GSFL in the residential sector.

10.2.2 Incandescent Reflector Lamps

Similar to DOE’s treatment of separate product classes based on CCT for GSFL, DOE

forecasts IRL shipments by aggregating acros s all IRL product classes (standard-versus

modified-spectrum, high-versus-low voltage, and high-versus-low diameter). In each of these

cases of aggregation, DOE used a representative product class (standard-spectrum, low-voltage,

high-diameter IRL) to evaluate lamp designs. DOE believes that the national impacts will be

similar for other product classes not directly an alyzed. By aggregating the product classes, DOE

assumes that there will be no significant migra tion of shipments or stock between lamps in

different product classes.

The IRL shipments model forecasts IRL socket growth in both the commercial and

residential sectors, reflecting new construction in each sector. As with GSFL, DOE uses EIA’s

AEO2008 to project residential building stock growth and commercial floor space growth.

Additionally, in the residential sector, DOE m odels a trend toward an increasing number of

sockets per home. DOE conducted an analysis th at estimated the average number of recessed

cans in homes between 2005 and 2042. Using Califor nia data on recessed cans per home, broken

out by home age 3 

## , DOE assumed new homes constructe d after 2005 would in stall the same

number of recessed cans per home as homes constructed between 2001 and 2005. DOE also

assumed that half of the homes constructed before 2001 would be renovated by 2042 to have an

equal number of recessed cans per home as newly constructed homes. DOE estimated the

distribution of homes by age usi ng U.S. Census data on new build ing starts in the residential

sector 4 

## . DOE estimated new construction and the num ber of future homes constructed in each

year from EIA’s AEO2008. Using this data, DOE estimated that the average number of recessed

cans per home in 2005 was 4.82 and the average number of recessed cans in homes in 2042

would be 8.52. Finally, to estimate the socket growth rate in each year, DOE multiplied the

number of recessed cans in homes by the projected stock of homes in each year according to

EIA’s AEO2008. Combining these two sources, DOE predicts an average growth rate of 2.6

percent between 2006 and 2042. The model ships la mps every year to replace retiring lamps and

to meet growth in the stock of lamps. DOE mo dels lamp designs based on three lumen packages

in the commercial and residential sectors: 630, 1,050 and 1,310 lumens (lm). Consumers who

## 10-8 purchase lamps with a particular lumen package in the base case generally purchase lamps with

that same lumen package in the standards-case.

Similar to the GSFL shipments forecast, DOE establishes the timing of lamp

replacements by tracking lamp shipments and then predicting when those lamps will retire based

on their service lifetimes. As discussed in the LCC and PBP analysis (Chapter 8), DOE

calculates the service lifetimes of lamps by dividing the lamp lifetime in hours by the annual

operating hours. As discussed in the energy us e characterization (Chapt er 6), DOE uses five

different operating hours to ch aracterize the usage of incande scent reflector and reflector

compact fluorescent lamps in th e residential sector. By usi ng different operating hours, DOE

effectively varies the service lives of the modeled lamps, thereby affecting shipments.

10.3 BASE CASE INPUTS AND FORECASTS

This section does the following: 1) descri bes the two base case scenarios DOE employs

in its analysis and the base case input market-sha re matrices for GSFL and IRL; 2) presents the

base case forecasts for each lamp type along with historical lamp shipments data; and 3) presents

base case forecasts for each lamp type with each lamp design and lamp-and-ballast design. The

base case input market-share matrices correspond to the matrices intr oduced above in Section

10.2

.

10.3.1 Base Case Scenarios Analyzed

DOE recognizes that rapidly emerging new lighting technologies could penetrate GSFL

and IRL markets and significantly affect shipme nt forecasts. These technologies, such as

reflector compact fluorescent lamps (R-CFL), ceramic metal-halide (CMH), and light-emitting

diodes (LEDs), already are, or eventually w ill be, significantly more efficacious and longer

lasting than the lamps they repl ace. If these emerging technologi es achieve their potential, they

may significantly affect the benefit calculations fro m efficiency standards. However, to calculate

NES and NPV change do to emerging technologies, DOE would need to accurately forecast the

anticipated price and performa nce points of each emerging technology—a difficult and highly

speculative task. Because of this high degree of uncertainly, DOE chose to analyze two base

case scenarios for both GSFL and IRL: 1) “Existing Technologies” and 2) “Emerging

Technologies.” DOE believes evaluating two base case scenarios will more completely and

transparently characterize the uncertainty in estimating emerging technologies’ market

penetration and the consequent impact on NPV and NES. Incorporating emerging technologies

in the base case does not affect the relative benefits of each TSL and prevents uncertain

projections of market share, price, or performance from obscu ring the benefits derived from

more efficient GSFL and IRL alone.

The assumptions and methodology that drive thes e scenarios vary slightly between GSFL

and IRL, and the details specific to each are described in section 10.3.2 and 10.3.3 , respectively.

In general, DOE calculated the market penetrati on of each of the analyzed emerging technologies

## in each year from 2006 through 2042, assessing each sector separately. DOE determined the

market penetration of the techno logy option that achieved the highe st level of penetration in each

year in each sector. DOE then decreased the analy zed market size in each year in each sector by

the amount that corresponded to the highest level of market penetration achieved by a

technology. For example, in the Emerging Tech nologies base case scenario, DOE effectively

reduced the 2042 IRL residential market size by 60 percent to reflect expected LED market

penetration, which was the highest of all analyzed emerging technologies.

For its base case analysis, DOE estimated the market penetration of three specific

technologies into the projected in stalled stock: LED lamps, CMH lamps, and reflector CFL. In

general, the Existing Technologies scenario only considers the ma rket penetration of

technologies that have reached maturation in term s of price and efficacy. Specifically, R-CFL is

the only technology that DOE considered in the Existing Technologies scen ario, and only within

the IRL market. For GSFL, no technologies ou tside those covered by this rulemaking were

analyzed in the Existing Technologies scenario.

The Existing Technologies scen ario assumes more limited penetration of other higher

efficacy products than the Emerging Technologies scenario. Thus, the Existing Technologies

scenario will yield greater NES than the Emer ging Technologies scenario because the latter

assumes a base case in which annual stocks compri se a greater level of higher efficacy products.

Therefore, the efficacy differential between thos e products and those in the standards-case will

be smaller than the differential between Existing Technologies (lower effi cacy products) and the

standards-case products.

In the Emerging Technologies scenario, DOE at tempts to forecast the market penetration

of both mature technologies and those technologies that are still undergoing significant changes

in price and efficacy. Specifically, DOE consid ered the market penetr ation of R-CFL, LED

lamps, and CMH lamps in the Emerging Technologies scenario.

DOE generally followed a 5-step process for each scenario to estimate the market

penetration of the analyzed t echnologies and account for their impact on NES and NPV.

First, DOE developed price, performance, and efficacy forecasts for each of the analyzed

technologies. Second, using those estimates, DOE calculated the payback period (PBP) of each

technology in the relevant sect or using the difference between its purchase price, annual

electricity cost, and annual lamp replacement cost relative to the lamp it replaces. Specifically,

DOE uses the following formula to calculate simple PBP:



## //($ Re )//($ )/($Pr

y klm Cost placement Lamp Annual yrklm CostyElectricit Annual klmice Purchase ack SimplePayb

Δ+ Δ Δ

−

=

Where:

- The Δ represents the difference between the two lamp options compared.

- Purchase Price includes the lamp price, and, in the case of the new and retrofit

markets, the fixture price.

10-9

## 10-10 - Annual Electricity Cost is a function of the mean annual operating hours and

efficacy for each lamp option, the elect ricity price, and the lumen demand.

- Annual Lamp Replacement Cost is a function of the mean lamp life, annual

operating hours, and lamp price, as well as labor charge.

Third, DOE used the relationship between PBP and market penetration to predict the

market penetration of each tec hnology in the relevant sector in every year from 2006 to 2042.

The relationship, which was used to estimate th e penetration of solid-state lighting in a DOE

report, predicts the market pe netration based on the PBP of a technology. DOE assumed this

relationship is valid for other em erging lighting technologies. That is, given a PBP of a certain

duration, a technology can be expected to achieve a certain market penetration; the higher the

PBP, the greater the expected ma rket penetration. DOE used a 5-year average of the market

penetrations predicted by the relationship as it s final market penetration. The 5-year average

represents the time DOE assumed it takes products with lower PBPs to penetrate the market.

Fourth, when necessary, DOE applied a scaling factor to the predicte d market penetration

to account for observed market trends. Fifth, as stated above, DOE reduced the projected

installed stock of covered products in each year by the value that corresponded to the highest

level of market penetration achie ved in each year by one of the analyzed technologies. Thus, RCFL and emerging technologies have the effect of lowering the energy savings of a potential

new standard. For those covered lamps remaini ng, the cost effectiveness of LCC savings and

thus the relative cost effectiveness of each TSL is not affected.

10.3.2 General Service Fluorescent Lamps

10.3.2.1 Base Case Scenarios



## For the GSFL Existing Technologies scenar io, DOE analyzes only the fluorescent

technologies covered by the rulemaking because it believes that no mature technologies in the

current market show the potential to significan tly penetrate the GSFL market. (T5 lamps, a

rapidly growing market, are considered in the analysis as covered products). In the GSFL

Emerging Technologies scenario, however, DOE se parately considered the potential market

penetration of two technologies: 1) LED (into the commercial, residential, and industrial

sectors), and 2) CMH (into the comme rcial and industrial sectors).

For its analysis of LED mark et penetration, DOE found a co mmercially available retrofit

kit that included a LED replacement for a 4-foot medium bipin lamp-and-ballast system. DOE

used the retrofit kit as a current baseline from which to project future cost, efficacy and price

points. DOE interviewed an integrated circuit manufacturer to develop cost estimates for LED

driver circuits. For cost estimates of othe r components, DOE used prices of existing LED

products already on the market, which it modified in accordance with cost data and efficacy

projections from DOE’s Solid Stat e Lighting Multi-Year Program Plan. 5 

## Lastly, after applying a

markup based on currently available LED lamps, DOE arrived at price and efficacy projections

for the LED luminaire in the retrofit kit 6 

## . For further detail on DOE’s price and efficacy

forecasts of potential LED replacements, see ap pendix 10C of the TSD. Following the 5-step

## 10-11 process described above, DOE calcu lated a 41 percent market penetr ation rate of LED lamps into

the 4-foot GSFL commercial se ctor by 2042. In the residentia l sector, the LED option did not

have a low enough payback period to result in any market penetrati on. DOE assumed LED

lamps penetrated only the new construction, renovation, and fixture replacement markets

because these lamps would require their own specific fixtures.

DOE also analyzed the potential penetration of CMH into the GSFL market. DOE first

estimated current CMH prices using a met hodology similar to the methodology it used to

estimate GSFL and IRL prices, as described in the product price dete rmination. (See TSD

chapter 4.) Industry experts informed DOE that CMH efficacies and lifetimes would increase

over the next several years while prices would remain constant. Applying these lifetime and

efficacy projections, DOE compared CMH replacem ents to GSFL systems. As a result, DOE

assumed no market penetration CMH because it found that T5 lamp systems (standard output

and high output) would always be more less co stly and more efficacious than projected CMH

replacements. Given this information, DOE believes that it is likely that migration to CMH

(from the GSFL market) will be dominated by th e migration to standard and high output T5

lamps.

10.3.2.2 Historical Shipments



## As discussed in Chapter 3, DOE received 2001-to-2005 historical shipments from NEMA

for 4-foot medium bipin, 8-f oot single pin slimline, and 8- foot recessed double contact HO

lamps. DOE also received confidential 2001-to- 2005 shipments of 4-foot MiniBP T5 SO and

HO lamps, and confidential shipment data for 2006 and 2007 for all lamp types. These

shipments were broken down by lamp length, diameter, shape, and high output. Because DOE

received confidential-only shipments for 4-foot T5 MiniBP SO and HO GSFL, DOE calculated

historical shipments of these lamps based on the assumption that they represented 2 percent of

the market in 2004, a figure that grew in 2005. 7 

## DOE assumed the T5 market is split evenly

between standard output and high ou tput. Recognizing that these sh ipment estimates reflect only

the shipments of NEMA members, DOE increases these estimates to account for the volume of

GSFL that non-NEMA lamp companies import or manufacture. DOE believes that these NEMA

shipments represent about 90 pe rcent of the GSFL market. Table 10.2 provides historical GSFL

shipments estimates for the entire U.S. market.

## 10-12 10.3.2.3 Calculation of Installed Stock in 2005



## DOE calculates lamp and ballast stocks in 2005 of T8 and T12 4- foot medium bipin

GSFL, 8-foot single pin slimline GSFL, and 8-foot recessed double contact HO using historical

shipment data from NEMA. DOE calculates the 2005 lamp stock by summing backward from

2005 for the years that correspond to the service lifetime (i.e., the lifetime in hours divided by

operating hours per year) of each lamp type. DOE disregards the 2005 stock of 8-foot T8

recessed double contact HO lamps in its analysis because the stock was relatively small.

As for the 4-foot T5 MiniBP SO and HO la mps, DOE did not rece ive public historical

shipments data therefore followed slightly diffe rent methodology to calcula te their installed 2005

stock. First, DOE first estimated 2001-to-2005 sh ipments based on assumptions derived from its

market research and supported by manufacturer interviews. As discussed above, market

literature indicated that 4-foot MiniBP T5 lamps represented 2 percent of the 2004 GSFL market,

a figure DOE assumed for its analysis. DOE’s res earch also indicated that the combined market

share of 4-foot MiniBP T5 SO and HO lamps wa s growing as a percentage of the overall GSFL

market. Additionally, manufacturers estimated in interviews that current 4-foot MiniBP T5

shipments are split evenly between standard output and high output lamps. Using these

assumptions, DOE generated historical shipment estimates for 2001 to 2005. It used these

shipments estimates to calculate the initial stock of 4-foot MiniBP SO and HO lamps in the same

manner it does for all other GSFL product classes. DOE models 4-foot MiniBP T5 shipments to

be half standard output and half high output. (However, due to differing lifetimes, this does not

imply an equal installed stock for each product class.) Finally, DOE received confidential

aggregated (both SO and HO) T5 lamp shipment data from NEMA for 2001 to 2007. DOE used

this data to validate its installed stock estimates.

As it relates to the residential sector, DOE cal culated the initial stock of 4-foot medium

bipin T12 lamps using the lamps sold through th e DIY distribution chain, which accounted for

approximately 25 percent of NEMA ’s historical shipments. Ne xt, DOE assumed 20 percent of

those DIY sales went to small commercial consumers, with the remaining 80 percent apportioned

to the residential sector. As a result, DOE assumed 20 percent of all 4-foot medium bipin

shipments went to the residential sector and all of those were T 12 lamps. From those shipments,

DOE calculated the residential installed stock and then modeled new construction, renovation,

and fixture/ballast replacement in th e same manner described in section 10.2.1

.

Using the 2005 lamp stocks, DOE calculated th e installed ballast st ocks by dividing the

total stocks of lamps by the number of lamps per ballast system. Finally, to accurately forecast

lamp and ballast shipments, DOE established a ballast age distribution for the installed ballast

stocks using trends in ballast shipments, calibra ted to shipment data for 2006 and 2007. Because

historical shipments indicate that the 8-foot recessed double contact HO market is relatively flat,

DOE uses a constant ballast age distribution for these ballast systems.

Based on manufacturer interviews, DOE assumes historical 4-foot T12 medium bipin, 8-

foot T12 single pin slimline, and 8-foot T12 recessed double contact GSFL represent lamp

shipments for installation on magnetic ballasts. DOE assumes that histor ical shipments of all

other GSFL represented lamps shipped for instal lation on electronic ballasts. DOE establishes

## 10-13 the corresponding ballast age distributions base d on the decline in magnetic ballast shipments

obtained from 2002 and 2005 U.S. Census Bureau data. 8

## 10.3.2.4 Base Case Market-Share Matrices



## As discussed in the engineering analysis (Chapter 5) and the LCC and PBP analyses

(Chapter 8), consumers have a va riety of choices in lamp and la mp-and-ballast systems. When

choosing lighting systems, consumers often make th eir choices considering lamp attributes such

as lifetime, efficacy, price, lumen output, rated wattage, and total system power. As discussed

earlier, the shipments for GSFL depend on such i nput assumptions as lamp lifetime and system

lumen output. In addition, other lamp or lamp-a nd-ballast system properties such as price and

energy consumption are key inputs to the NES a nd NPV calculations. Therefore, within each

product class, DOE believes it is necessary to di rectly account for the mix of technologies that

consumers select in the base case and standards-case. To ac count for the range of possible

consumer choices, DOE develops and populates technology market-share matrices. These

market-share matrices allocate percentage market shares to each lamp-and-ballast design for the

base case and standards-case by prop ortioning shipments. As discu ssed in the NIA (Chapter 10),

the base case and standards case efficacy forecas ts also depend on the market-share matrices.

The GSFL shipments model incorporates seve ral separate market-share matrices to

characterize shipments of lamps and lamp-and-ba llast systems at different times during the

analysis period. Because the lamp design te chnology mix may change over time, DOE defines

separate market-share matrices for systems purchased in 2012 and earlier and for systems

purchased in 2042 for each analyzed system type (e .g., 4-foot T8 medium bipin). To determine

the technology mix of the shipments for the interm ediate years of the analysis period, DOE used

a linear progression from 2012 to 2042. For each lamp type and market-share matrix, DOE

generates the lamp-and-ballast designs by pairing each lamp design (as presented in Chapter 5)

## 10-14 with commercially available ballasts that exhi bit the most common ballast factors. This

produces both energy-saving a nd non-energy-saving options.

Table 10.4 through Table 10.14 illustrate the base case market-share matrices for GSFL.

DOE developed the percentage inputs to these ma trices based on discussions with manufacturers

and industry experts. In addi tion, DOE analyzed the quantitie s of commercially available

products to develop the breakdown of per centage shipments by lamp efficacy. As Table 10.4

, Table 10.8

, Table 10.10 , and Table 10.12 indicate, DOE assumes that in the base case, the

technology mix of 4-foot T8 medium bipin (in the commercial sector only), 8-foot T8 single pin

slimline, and 8-foot T12 recessed double contact HO lamp-and-ballast ge nerally migrates to

higher efficacy and lower ballast factors over th e analysis period. DOE assumes the distribution

of other lamp types remain constant over the analysis period.

## 10.3.2.5 Base Case Forecast Results



## Figure 10.3.1

, Figure 10.3.2

, Figure 10.3.3 , and Figure 10.3.4 present the base case

shipments forecasts from 2012 to 2042, modeled from the 2005 installed stock based on 2001-to## 10-24 2005 historical shipments. Figure 10.3.1

, Figure 10.3.2

, Figure 10.3.3 , and Figure 10.3.4

correspond to 4-foot medium bipin shipments, 8-foot single pin slimline shipments, 8-foot

recessed double contact HO shipments, and 4-foot T5 SO and HO, respectively. Each figure

shows both the Existing Technologies a nd Emerging Technologies scenarios.

In accordance with historical shipment data, Figure 10.3.1 shows a decline over the

analysis period in shipments of 4-foot T12 me dium bipin lamps. Th ese retired 4-foot T12

medium bipin lamp-and-ballast systems are repl aced with 4-foot T8 medium bipin lamp-andballast systems upon ballast retirement. A declin e in the commercial sector accounts for the

majority of the reduction of the 4-foot T12 lamp shipments. As discussed earlier, DOE forecasts

that 90 percent of retiring 3-lamp 4-foot T12 magnetic systems are replaced by one- and 2-lamp

electronic 4-foot T8 systems, while 10 percent are replaced with the same 3-lamp T12 magnetic

systems. DOE also forecasts that 80 percent of retired 8-foot T12 si ngle pin slimline systems

will be replaced with 4-foot T8 medium bipi n lamp systems, which accounts for much of the

increase in T8 systems. Along with the 4-foot T8 systems purchased to meet demand from the

new construction, fixture replacement and renovati on markets, this accounts for the increase in

4-foot T8 medium bipin shipments through the an alysis period. Four-foot T12 systems remain

present throughout the analysis period as they are shipped as replacements on magnetic ballasts

in the residential sector. A dditionally, 10 percent of retire d 8-foot T12 single pin slimline

systems will be replaced with el ectronic 4-foot T12 medium bi pin systems in the commercial

sector.

For 4-foot T8 lamps, the penetration of LED lamps in the base case is represented by the

difference between the Emerging and Existing Technol ogies scenarios. As discussed previously,

DOE’s analysis showed no market penetration of LED lamps into the residential market.

Furthermore, the available market for emerging t echnologies is composed of fixture replacement,

renovation, and new construction. Because T12 lamps are only shipped in ballast replacement

and lamp replacement events, there is no modeled impact of emerging technologies with regard

to 4-foot T12 systems. Thus, 4-foot T12 shipme nts are equivalent in each base case scenario.

## 10-25

## In accordance with historical shipment data, Figure 10.3.2 shows a decline in shipments

of 8-foot T12 single pin slimline lamps. Eighty percent of these retired 8-foot T12 single pin

slimline lamp-and-ballast systems are replaced with 4-foot T8 medium bipin systems, which is

reflected in the decline illustrated below. Of the remaining 20 percent of retiring systems, 10

percent are replaced by 8-foot T8 single pi n slimline lamp-and-ballast systems upon ballast

retirement while 10 percent remain 8-foot T12 sy stems. This accounts for the growth in 8-foot

T8 single pin slimline lamp shipments until 2018, wh en a declining stock of retiring 8-foot single

pin slimline T12 lamps no longer generates enough T8 replacements to maintain positive growth

construction, renovation, and fixture replacemen t markets, which DOE assumes are serviced by

4-foot T8 medium bipin, 4-foot T5 standard output systems, and other emerging technologies,

such as LED (in the Emerging Technologies scenario). Thus, the Emerging and Existing

Technologies base cases are th erefore equivalent for 8-foot single pin slimline lamps.

## Figure 10.3.3 shows that 8-foot T12 recessed doubl e contact HO lamp shipments decline

rapidly in the base case, which reflects a co ntinuation of confidentia l shipments data. As

discussed earlier, DOE decided not to model th e 2011 stock of 8-foot T8 recessed double contact

HO lamps, resulting in zero forecasted shipments in the base case. The decline is due to existing

technologies that DOE believes are penetrating the fixture replacement, new construction, and

renovation markets. DOE assumed most lighting systems purchased due to new construction are

4-foot T5 HO or other existing t echnologies such as HID. Ther efore, the Emerging and Existing

Technologies are the equivalent for the 8-foot re cessed double contact high output product class.

## In accordance with confidential shipment data, Figure 10.3.4 depicts increasing

shipments of 4-foot T5 standard output and hi gh output lamps. DOE allo tted a portion of the 4-

foot MBP fixture replacement, renovation, and new construction markets to 4-foot T5 SO

systems, driving the increase in SO shipments. Similarly, DOE assumed 4-foot T5 HO systems

completely penetrate the 8-foot RDC HO market, which accounts for the former’s increase over

the analysis period. In the Ex isting Technologies scenario, four-f oot T5 SO shipments slightly

exceed those in the Emerging Technologies scenar io because SO lamps are modeled to service

new construction, fixture replacement, and renova tion events which are being penetrated by LED

lamps in the Emerging Technologies scenario. This yields a smaller stock of systems to migrate

to 4-foot T5 SO lamps. For 4-foot T5 high output lamps, the Emerging and Existing

Technologies scenarios are equivalent because DOE’s analysis found that these lamps would

always be more cost effective than CMH alternat ives. Thus, there is no penetration of emerging

technologies into the 4-foot T5 high output market. SO ar e coming from commercial new

construction, fixture replacements, and renovation.

accounts for shipments due to new construction, lamp shipments for replacing failed lamps and

failed ballasts dominate this market. In additi on, lamp replacement shipments are greater than

ballast replacement shipments for all five product classes of GSFL. This effect is due to the

much longer lifetime, and therefore fewer re placements, of ballasts relative to lamps.

10.3.3.1 Base Case Scenarios Analyzed



## As with GSFL, DOE considered two base cas e scenarios for IRL: Existing Technologies

and Emerging Technologies. Because DOE believe s that R-CFL are a mature technology with

relatively stable price points and efficacies, DOE considered R-CFL penetration into the

residential market in the Existing Technologies scenario. DOE did not consider migration to

LED and CMH in the IRL Existing Technologies scenario. Therefore, the highest market

penetration value (and reduction in market size) for the IRL Existing Technologies base case

reflects R-CFL penetration in each year, as it is the only technology DOE analyzed.

In contrast, for the Emerging Technologies scenario DOE considered the market

penetration of R-CFL, LED, and CMH lamps in both the residential and commercial sectors.

DOE separately calculated the penetration of each technology into the IRL stock by using the 5-

step process described above. The technology th at achieves the maximum market penetration

varies over the analysis period.

10-32

## 10-33 To model R-CFL penetration, DOE developed price forecasts based on historical pricing

trends of CFL and R-CFL, using a methodol ogy similar to the methodology DOE used to

estimate GSFL and IRL prices, as described in the product price dete rmination. (See TSD

chapter 4.) DOE assumed no future change in efficacy. Using this data, DOE found the market

penetration predicted by the PBP relationship. However, DOE believes that R-CFL may not

always be appropriate in applic ations where IRL are used due to differences in color quality,

size, dimming capability, and other factors. DOE observed that the actual market penetration of

CFL replacements for A-line incande scent lamps thus far has been approximately 40 percent of

the penetration predicted by the PBP-penetration relationship. Therefore, DOE applied these

same scaling-factor reductions of 40 percent and 36 percent in calculating the market penetration

of R-CFL into the IRL market for the reside ntial and commercial sectors, respectively.

For LED and CMH lamps in IRL market, DOE developed price and efficacy forecasts

using a methodology similar to the one described above for GSFL. Industry experts informed

DOE that CMH efficacies and lifetimes would incr ease over the next several years while prices

would remain constant. To develop LED lamp prices, DOE followed the same methodology it

used in the GSFL-to-LED analysis. Using this in formation, DOE derived the necessary inputs to

the PBP-penetration relationship for CMH and LED lamps. DOE did not apply the scaling factor

reduction to the predicted LED a nd CMH market penetration rate s that it used for the R-CFL

analysis. DOE believes the substitutability pr oblems that arise when R-CFL replace IRL do not

apply when LED and CMH replace IRL.

By the methodology described, DOE arrived at market penetration values (and market

size reductions) for each base case scenario. For the Existing Technology scenario, 2042 R-CFL

penetration reached 38 percent in the residential s ector and 20 percent in the commercial sector.

(This was the highest market penetration because it was the only technology analyzed for the

scenario.)

For the Emerging Technology scenario, LED re ached the highest market penetration of

any analyzed technology in both the residentia l sector and the commer cial sector. DOE’s

analysis found LED lamps could penetrate 40 per cent and 82 percent of the IRL installed stock

by 2042 in the residential and commercial sector , respectively. DOE’s results support a

comment by Industrial Ecology stating that emergi ng technologies will enter the commercial

market first. (Public Meeting Tr anscript, No. 21 at p. 308) This effect occurs because there are

higher installation and operating co sts in the commercial sector relative to the residential sector,

resulting in lower PBPs and faster migration to emerging technologies. Again, DOE used these

results to effectively reduce the size of the IRL market for its analysis.

10.3.3.2 Historical Shipments



## As discussed in Chapter 3, DOE received hist orical shipments of IRL aggregated for the

commercial and residential sectors from 2001 to 2005 from NEMA. NEMA broke these

shipments down into parabolic reflector (PAR) in candescent, reflector (R) incandescent, PAR38

## 10-34 halogen, and PAR30 and PAR20 halogen lamps. Recognizing that these shipment estimates

only reflect shipments of NEMA members, DOE increases these estimates to account for the

volume of IRL that are impor ted or manufactured by non-NE MA lamp companies. DOE

believes that these NEMA shipments represent approximately 85 percent of all halogen

shipments and 70 percent of incandescent shipments.

Certain ER, BR, and R-shaped IRL ( e.g., BR 30 and BR40 65 Watt) are exempted from

energy conservation standards. To account for these exemptions, DOE estimated the market

share of these exemptions using a combination of manufacturer product catalog research and

additional shipment data submitted by NEMA. 10 

## Because research indicated that these

exemptions constitute approximately 60 per cent of all incandescent (non-halogen) IRL

shipments, DOE decreases the NEMA historic al incandescent shipments and the base case

installed stock accordingly.

In addition, because DOE’s IRL shipment m odel separately forecasts IRL shipments in

the commercial and residential sectors, DOE esti mates certain portions of IRL shipments to each

sector. DOE used a reflector lamp study conduc ted by the New York State Energy Research and

Development Authority 11 

## to estimate that about 33 percent of non-halogen shipments serve the

commercial sector and about 67 perc ent serve the residential sector. Similarly, DOE allocates 60

percent of halogen lamp shipments to the comme rcial sector and 40 perc ent to the residential

sector.

Table 10.15 shows the resulting historical covered IRL shipments estimates for the entire

U.S. market.

## 10.3.3.3 Calculation of Installed Stock in 2005



## To forecast IRL shipments from 2006 to 2042, DOE first estimates the IRL stock in 2005

using the above historical shipment data. DOE then forecasts IRL shipments from 2006 to 2042

by applying growth, replacement rate, and emergi ng technologies assumptions. The growth rate

methodology and assumptions that DOE use are described in section 10.2 10.2.2 . The average

lifetime of halogen lamps and, th erefore, the replacemen t rates, derive from the assumed base

case technology mix of IRL in the commercial and residential sectors, which is reflected in the

market-share matrices in section 10.3.3.4 . DOE assumed incandescen t IRL have a lifetime of

2,000 hours, as this is the most common incandescent lifetime on th e market today. With this

inputs, DOE calculated that the 2005 stock of c overed IRL is approximately 224 million lamps in

the residential sector and 64 million lamps in the commercial sector.

## 10-35 10.3.3.4 Base Case Market-Share Matrices



## As discussed in the engineering analysis (Cha pter 5) and the LCC an alysis (Chapter 8),

consumers have a variety of choices in IRL. IRL shipments strongly depend on lamp lifetime.

In addition, other lamp propertie s such as price and energy consumption are key inputs to the

NES and NPV calculations. Therefore, within IRL in the commercial and residential sectors,

DOE believes it is necessary to directly account for the mix of technologies that consumers

select in the base case and st andards-case. To account for the range of possible consumer

choices, DOE develops and populat es technology market-share matr ices. As discussed in the

national impact analysis (NIA; Chapter 10), the base case and standards case efficacy forecasts

also depend on the market-share matrices.

The IRL base case market-share matrices a pportion the installed lamp stock in 2011 and

2042 by percentage market shares of each IRL lamp design. Given these two inputs, DOE

creates a dynamic base case and assumes that the percentage stock values change linearly

through the analysis period. Once DOE establis hes the percentage stock in each year, DOE’s

model then ships lamps to maintain the stock di stribution, taking into account lamp replacements

and new construction.

DOE develops the percentage inputs to the base case market-share matrices based on

discussions with industry expert s and an examination of manuf acturer product catalogs. As

stated earlier, DOE models three separate lume n packages in the commercial and residential

sectors: 630 lm, 1,050 lm and 1,310 lm. These lu men packages correspond to the 50W, 75W,

and 90W baseline halogen technolo gies, respectively. An examin ation of manufacturer product

catalogs indicates that 27 percen t of the covered IRL market is at 630 lm, 32 percent is at 1,050

lm, and 41 percent is at 1,310 lm. DOE applies th ese percentages to the 2011 inputs to the base

case market-share matrices for the commercial and residential sectors.

In addition, based on manufacturer intervie ws, in the commercial sector DOE assumes

that 80 percent of the 2011 inst alled IRL stock is based on hal ogen technology, while 20 percent

of installed IRL is of the more efficacious ha logen infrared (HIR) technology. Because DOE

expects a natural migration toward more efficaci ous IRL, DOE assumes that the installed IRL

stock in the commercial sector in 2042 is 50 percent halogen and 50 percent halogen infrared. In

contrast, in residential base case DOE assumes that 100 percent of inst alled IRL is halogen

technology in 2011 and remains constant throughout the analysis period.

Table 10.16 and Table 10.17 provide the base case market-share matrices for IRL in the

commercial and residential sectors.

## 10.3.3.5 Base Case Forecast Results



## Figure 10.3.9 depicts the base case shipment forecasts for all sectors of IRL from 2006 to

2042, and shows historical shipments from 2001 to 2005. The forecasted shipments in the

Existing Technologies scenario e ssentially increase throughout th e analysis period, reflecting

both building and floor space growth and the trend toward more IRL per new home. These

effects are offset, most no ticeably from 2005 to 2012, by continued growth and market

penetration of CFL, albeit at decl ining rates. DOE believes the historical growth rate of the IRL

stock (approximately 8 to 10 percent annually —much higher than AEO2008’s predicted building

and floor space growth) is unsustainable. Conf idential NEMA shipment data from 2006 and

2007, which show significant declines from 2005, support this assumption, Therefore, DOE

bases IRL socket growth after 2005 on the AEO 2008 projected growth ra te in building floor

space, combined with the assumption that new-home construction and existing-home renovations

in the residential sector will contain an incr easing number of sockets per home (see section

10.2.2 ).

## The Emerging Technologies scenario results in a similar but more pronounced pattern of

declining shipments followed by gradually increa sing shipments, as this scenario accounts for

LED and CMH penetration in addition to CFLs. The continued introduction of additional CFLs

and other long-lived emerging technologies into the market mitigates replacement needs initially

as well, contributing to the for ecasted decline in shipments.

10.4 STANDARDS CASE INPUTS

10.4.1 General Service Fluorescent Lamps

10.4.1.1 Shipments Scenarios



## To characterize consumer behavior in the standards-case, DOE considers many lampand-ballast system properties that consumers ta ke into account when purchasing their GSFL

systems. Specifically, DOE regards system pr ice, system energy consumption, and system

lumen output as three key drivers of consumer purchases.

DOE develops two sets of two shipments scen arios, or four standards-case scenarios in

all, to characterize consumers that may weigh thes e factors differently. Th e first set of scenarios

comprises the “Roll-up” and “Shift” scenarios; the second se t comprises the “H igh” and “Market

segment-based” lighting expertise scenarios. (Each scenario is detailed below.) To evaluate a

standards-case, DOE models a standards-case scen ario and compares it to the base case. One

standards-case scenario, for example, would be the Roll-up, High lighting expertise scenario;

another would be the Shift, Market Segment-Base d expertise scenario. DOE thus considers four

standards-case scenarios and two base case scenar ios, yielding eight total sets of results.

10-38

## 10-39 The first set of standards-case scenarios for GSFL includes the “Roll-up” and “Shift”

scenarios. The Roll-up scenario represents a stan dards-case in which all product efficacies in the

base case that do not meet the sta ndard would roll up to meet the new standard level. Consumers

who in the base case purchase lamps above the st andard level are not a ffected as they are

assumed to continue to purchase the same base case lamp or lamp system in the Roll-up

scenario. The Roll-up scenario characterizes cons umers primarily driven by the first-cost of the

lamp. In contrast, the Shift scenario models a standards-case in which all base case consumer

purchases are affected by the standard (whether or not their base case efficacy is below the

standard). In this scenario , any consumer may purchase a reduced-wattage lamp. As the

standard level increases, market share incrementa lly accumulates at TSL5 because it represents

“max tech” (i.e., moving beyond it is impossible). The Shift scenario characterizes consumers

primarily concerned with system energy cons umption, and reflects an upper bound scenario.

The following discussion presents the standards-case decision-making process

characterized by the Roll-up scenario. Lamp-and -ballast designs from which consumers choose

are presented in the market-share matrices.

1) If consumers buy a system in the base case th at complies with the standard, then they

buy the base case system.

2) If consumers do not buy a standards-compliant system in the base case, then they

a. consider only systems that have a lumen output that is within 10 percent of the

base case lumen output;

b. select the lowest first-cost lamp-and-ballast design; or

c. if there are two lamp-and-ballast designs with equal installed prices, they select

the one with a lumen output that is closest to the base case lumen output.

The following discussion presents the standards-case decision-making process

characterized by the Shift scenario.

1) If consumers buy the least efficacious lamp-and-ballast design in the base case, they

then

a. consider only systems that have a lumen output that is within 10 percent of the

base lumen output;

b. select the lowest first-cost lamp-and-ballast design; or

c. if there are two lamp-and-ballast designs with equal installed prices, they select

the one with a lumen output that is closest to the base case lumen output.

2) If consumers do not buy the least efficacious lamp-and-ballast desi gn in the base case,

they then

a. never buy a system that has a greater i nput power than the base case system;

b. consider only systems that have a lumen output within 10 percen t of the base case

lumen output. If none exist, buy the ba se case system (if it is standardscompliant);

c. consider only systems that use less input power than the base case system. If

none exist, they buy the lowest first-cost (if two lamp-and-ballast designs have

equal installed prices, select the one with a lumen output that is closest to the base

case lumen output);

## 10-40 d. select the lowest first-cost lamp-and-ballast design; or

e. if there are two lamp-and-ballast designs w ith equal installed prices, select the one

with a lumen output that is clos est to the base case lumen output.

f. in general consumers seek to shift to an efficacy level that keeps their purchase

the same number of efficacy levels above the baseline as in the base case.

The second set of standards-case GSFL scenarios comprises the lighting expertise

scenarios: High and Market Segment-Based. Th is set of scenarios characterizes consumers’

decisions (or lack thereof) to either maintain equivalent light output upon the purchase of a new

higher efficacy lamp or accept higher lighting le vels. The High expertise scenario generally

characterizes more sophisticated lighting decisions in which cons istent lighting levels and/or

energy savings play a determinant role in consum er behavior. In this scenario, consumers are

more likely to choose a lower ballast factor to pair with higher efficacy lamps or reducedwattage lamps. These consumers therefore generall y save energy sure to st andards. Conversely,

in the Market Segment-Based scenario, DOE assumes consumers occasionally accept high

lighting levels as a consequence of their expertis e (or lack thereof). These consumers often seek

to purchase the same wattage lamp (with higher efficacy) and same ballast factor as in the base

case, thus often not saving energy as a result of standards. That expertise, and whether

consumers migrate to lower ballast factors, is based on the consumer type (owner, electrical

contractor, homebuilder, etc.) and the purchase ev ent (new construction, replacement, etc.).

DOE undertook an extensive literature review a nd analysis to characte rize the likelihood of

consumers migrating to lower ballast factor sy stems or reduce-wattage lamps if higher efficacy

standards are required. The results characteri ze the Market Segment-Based scenario. DOE’s

analysis is described briefly be low and in detail in Appendix 9A.

For its analysis, DOE first characterized the lighting market supply chain in the

commercial and residential sectors and identified the decision makers within each one (e.g.

, contractors, homeowners, etc.). DOE broke down each sector by the principal events that

prompt lamp purchases: ballast failure, retr ofit, fixture replacement, renovation, and new

construction. DOE assigned probabilities reflecting each decision maker’s likelihood of making

the lighting purchase decision give n the purchase event. DOE th en analyzed the likelihood of

each decision maker choosing to run a lamp on a lower BF ballast if forced by standards to

purchase a more efficacious lamp. DOE described that likelihood with a pr obability that was

based on the technical expertise and motivation of the decision maker. Within each purchase

event, DOE multiplied the likelihood of each ma rket actor making the decision by the likelihood

of that actor choosing a lower ballas t factor ballast. In this way, DOE derived an estimate for the

likelihood of a lower ballast factor being selected for each event in each sector in the standardscase.

DOE assumed the commercial and industrial se ctors behave similarly with respect to

ballast factor choices and no distinction was made between them in this analysis. Additionally,

decision makers in the large-commercial sect or can be different agents making different

decisions than those in the small-commercial sect or. In the market segments (purchase events)

where DOE found consumer behavior to be subs tantially different between these subsectors,

DOE weighted the relative impact of each subs ector when characterizi ng the overall commercial

## 10-41 market. Table 10.18 and Table 10.19 present results for the commercial sector and residential

sector, respectively.

10.4.1.2 Standards-Case Market-Share Matrices



## Similar to in the base case, DOE is constructing market-share matrices to characterize

shipments of lamps and lamp-and-ballast systems in the standards-case. These market-share

matrices provide the same lamp-and-ballast desi gns as the base case market-share matrices.

However, in the standards-case, some lamp de signs (and therefore lamp-and-ballast designs) are

not standards-compliant and ther efore precluded from being shi pped. In addition, in the

standards-case, the shipments model defines separate market-share matrices for the ballasts

installed before 2012 (initial ballasts) versus new ballasts installed after 2 011. This is important

in the standards-case since consumer purchase deci sions may vary in these two situations. If a

consumer with an existing installed ballast in 20 12 is forced to replace a base case lamp with a

different standards-compliant lamp, the consum er is limited to only those lamp-and-ballast

designs that maintain the current ballast. Howe ver, when a consumer purchases a new lamp-andballast system, either for retrofitting, ballast replacement, or new construction, all lamp-andballast systems, including those with ballast factor s different from the base case system purchase,

are available. Table 10.20 describes the inputs to the base cas e and standards-case market-share

matrices for initial and new ballasts.

** With the exception of the first lamp purchase after 2011, lamp replacement purchases are always the same as the

retiring lamp.

# Though they are presented as lamp-and-ballast design s, during the analysis period these matrices result in

shipments of lamps for lamp replacement purposes only.



## DOE uses the Shift and Roll-up scenarios to populate the standards-case market-share

matrices. Table 10.21 through Table 10.54 present the standards-case market-share matrices for

all analyzed GSFL in both the Shift and Roll-up scen ario. As seen in the standards-case marketshare matrices for initial ballast systems, the base case proportions of lamp-and-ballast systems

at each ballast factor are equivalent to the st andards-case proportions. This is because these

“initial ballast” standards-case matrices represen t only lamp replacements on previously existing

ballasts. In these situations, consumers are limited in their lamp-and-ballast designs and

therefore may not always be able to match the lumens of their base case system.

As seen in the standards-case market-share matrices for “new balla sts,” the distribution

among ballast factors in the standa rds case shows a clear migration to lower ballast factors. By

using a lower ballast factor with a higher efficacy lamp, consumers are better able to match the

lumens of their lamp-and-ballas t purchases with the lumens of their base case purchase.

The second set of standards-case scenar ios, High-versus-Market Segment-Based

scenario, also influences thes e market share matrices. Table 10.21 through Table 10.54 depict

the High lighting expertise scenario. Under the High lighting expertise s cenario, 100 percent of

consumers can either shift or roll-up based on th e factors they consider (energy savings, first

cost, etc.) in making their purchase. These c onsumers with high lighting expertise will attempt

to maintain lumen output by moving to a lower ba llast factor if necessary. However, under the

Market Segment-Based scenario, a certain percentage, based on the market segment, will only

roll-up and will not move to lower ballast factor s or reduced-wattage lamps to maintain lumen

output. DOE created market share matrices to ch aracterize these consumers. As an example,

Table 10.27 presents the 4-foot T8 medium bipin ne w ballast market share matrix for those

consumers characterized by low light ing expertise. Again, the selection of Shift or Roll-up has

no affect on these consumers—they onl y roll-up in the standards-case.

## 10.4.1.3 Early Retirement of Ballasts in the Standards-Cases



## The commercial GSFL shipments model incorpor ates early retirement (or retrofit) of 4-

foot T12 medium bipin and 8-foot T12 single pin slimline ballast systems in the standards-case.

As historical shipments indicate, in the base case, as magnetic T12 ballasts reach their end of

life, these systems are replaced by their electronic T8 counterpart systems. In the standardscases, DOE assumes that when consumers who own T12 magnetic ballasts are forced to

purchase more expensive standards-compliant lamp s, some consumers may instead discard their

magnetic ballast before its natural end of life to purchase a more cost-effective T8 electronic

system. As the standard level and lamp price in crease, DOE expects this rate of early ballast

retirement to increase as well. Table 10.55 summarizes DOE’s assump tions about early ballast

## 10-76 retirements in the standards-cases for 4-foot T12 medium bipin and 8-foot T12 single pin

slimline ballasts. Percentage a nnual retrofit rates re present the percentage of remaining T12

installed ballast stock that is retrofitted each year. Similarly, DOE models a higher conversion

rate from T12 to T8 systems in the residential sector with higher TSLs, as shown in Table 10.56

. Here, when T12 systems reach the natural end of their life, DOE assumes increasing portions of

residential consumers will replace those T12 syst ems with T8 systems at increasing TSLs. At

TSL4 and TSL5, all T12 systems are automatical ly replaced with T8 systems because no T12

lamps are standards-compliant. Figure 10.4.1 depicts how shipments of 4-foot T12 lamps

change in response to early retrofit rates, at TSL3, holding the resi dential conversion rate

constant at 0 percent. Similarly, Figure 10.4.2 depicts how shipments of 4-foot T12 lamps

change in response to residential conversion rate s at TSL3, holding early retirement rates of 4-

foot T12 systems constant at 0 percent.

10.4.2.1 Shipments Scenarios



## As with GSFL, DOE considers two sets of stan dards-case scenarios for IRL. The first set

of scenarios for IRL includes the “Roll-up” and “Shift” scenarios. Again, the Roll-up scenario

represents a standards-case in which all product e fficacies in the base case that do not meet the

standard would roll up to meet the new standard level. Those product efficacies that were above

the standard level are considered unaffected, as consumers continue to purchase the same base

case lamp or lamp system. In contrast, the Sh ift scenario models a standards-case in which all

base case consumer purchases are affected by th e standard (whether or not their base case

efficacy meets the standard). In the shift scenario consumers strive to maintain the same efficacy

differential (between their purchas e and the baseline) in both the base case and standards case.

For example, if in the base case, a consumer pur chases a lamp at EL3, he is purchase a lamp two

market efficacy levels above the baseline (EL1 represents a model lamp not commercially

available). Therefore under stan dards set at TSL3 (corresponding to EL3), that same consumer

will purchase IRL at EL5, two efficacy levels above the new baseline.

10-78

## 10-79 Because in the residential sect or, all consumers purchase at the minimum compliant level,

under energy conservation standards all consumers are forced to roll-up to the next highest

efficacy level. Therefore, in the residential sector, the Shift and Roll-up scenarios produce the

same results. In contrast, the IRL commercial se ctor responds to the Roll-up or Shift scenario

assumptions as GSFL does. Some commerc ial consumers who purchase lamps above the

minimum standard level in the base case may continue to do so in the standards-case.

The second set of standards-case IRL scen arios includes the “Product Substitution” and

“No Product Substitution” scenarios. In the Product Substitution scenario, DOE assumes

consumers purchasing regulated IRL in the base case do not necessarily continue to purchase

regulated IRL in the standards case. DOE t hus models a shift to both exempted BR lamps

(namely the 65W BR30 lamp) and to R-CFL in the standards-case.

Regarding migration to BR lamps, as di scussed earlier, EISA 2007 extended energy

conservation standards coverage to certain ER and BR while leaving others exempted. For the

product substitution scenario, DOE assumes that as the efficacy standard on IRL increases, some

consumers who would normally purchase a covere d IRL may instead choose to purchase higher

wattage, lower first cost, exempted 65 Watt BR lamps. Although these exempted lamps do not

fall under the scope of this rulema king, DOE includes the effect of consumer migration to these

lamps and other technologies in th e product substitution scenario.

To estimate the additional migration to exempted BR lamps in the standards-case, DOE

calculates PBPs for BR lamps relative to each lamp design (halogen, improved halogen, etc.).

Using these PBP values, DOE arrives at market penetration rates by employing the same PBPmarket penetration relations hip described in section 10.3.3.1 . DOE observed that in the

commercial sector the predicted market penetrat ion rates of halogen lamps into the BR market

are consistent with current mark et trends. DOE applies the rela tionship to the higher-efficiency

design options, such as HIR, to calculate increm ental market penetration of exempted lamps in

the standards-case. Specifically, as standards become increasingly stringent and require more

efficient technologies, an incr easing number of consumers mi grate to exempted lamps.

In the residential sector, however, DOE found that the market penetration predicted by

the PBP relationship between BR and halogen lamp s was not consistent with available market

data. DOE concluded residentia l consumers do not make purchase decisions based on PBP.

Therefore, DOE estimated the migration to th e exempted lamps based on available data on

market trends.

In each sector, DOE apportions the resultant market shares of the analyzed technologies

in the market-share matrices.

Additionally, DOE expects incr easing residential sector migration to R-CFL in the

standards-case as the technology matures and b ecomes relatively more cost-competitive. DOE

uses the same market penetration methodology as it does for the IRL existing and Emerging

Technologies base cases. For the residential sector DOE calculates simple payback periods

comparing R-CFL to the baseline halogen, and R-CFL to the higher-effi ciency lamp designs.

Using incremental market penetrations ba sed on the payback period calculations, DOE

## 10-80 incorporated additional movement to R-CFL in the residential sector standards-case. As

previously discussed, DOE observed that the actu al market penetration of R-CFL thus far has

been approximately 40 percent of the penetration predicted by the PBP-pene tration relationship.

DOE believes that R-CFL may not al ways be appropriate in applic ations where IRL are used due

to differences in color quality, size, dimming capability, and other fact ors. Therefore, DOE

applies scaling-factor reductions of 40 percent for the residential sector. In the commercial

sector, DOE assumes that all institutions wishi ng to convert to R-CFL despites the technology’s

substitutability issues (such as lower color quality) do so by 2012. Therefore, there is no

additional movement to R-CFL in response to standards in the commercial sector.

In the “no production substitution” scenario, DOE assumes consumers who purchase

covered IRL technology in the base case conti nue to purchase covere d IRL technology in the

standards-case ( i.e., the total number of installed covered IRL in the base case is the same as that

in the standards-case throughout th e analysis period). In this scenario, DOE does not model any

additional shift in the st andards-case to non-regulate d reflector technologies.

As discussed above with GSFL, to evaluate a standards-case, DOE models a standardscase scenario and compares it to the base case. One IRL standards-case scenario, for example,

would be the Roll-up, product substitution scen ario; another would be the shift, no product

substitution scenario. DOE thus considers four IRL standards-case scenarios and two base case

scenarios (existing technologies and emerging technologies), yieldi ng eight total sets of results.

In addition to modeling these two sets of s cenarios for IRL shipments, DOE develops a

“10-percent lumen increase,” in which DOE assume s that a portion of resi dential consumers of

IRL will buy a more efficacious lamp at the same wa ttage as in the base case. This incorporation

of non-energy-saving lamp designs results in an overall higher lumen output per IRL in the

residential sector. To quantify the percentage of consumers that purchase same-wattage lamp

designs, DOE assumes that the average initial lu men output of IRL of the standards-cases is 10

percent higher than that of the base case. DOE does not model this sensitivity scenario in the

commercial sector. Shipment results for the 10-pe rcent lumen increase sensitivity scenarios are

presented in Appendix 9A of this TSD. In a ddition to modeling these three scenarios, DOE’s

shipment spreadsheet also allows for the user to generate custom inputs into the base case and

standards-case market-share matrices. In a ddition to making available all lamp designs

discussed above (both reduced-watta ge and same-wattage lamp designs), the spreadsheet is also

capable of modeling an increased or decrea sed shift toward non-IR L technologies in the

standards-case.

10.4.2.2 Standards-Case Market-Share Matrices



## Similar to the base case, DOE constructs market-share matrices to characterize lamp

shipments in the standards-case. Table 10.58 through Table 10.61 display the lower- and upperbound scenario market-share matrices for IRL ship ments in each the commercial and residential

sectors. These market-share matrices provide th e same lamp designs as the base case marketshare matrices. However, in the standards-case, some lamp designs are not standards-compliant

and are therefore precluded fr om being shipped beginning in 2012. In the standards-case,

standards-compliant lamps do not occupy all IRL sockets until the lamps purchased before 2012

## 10-81 fail. For example, the longest-lived residential IRL in the base case has a service life of 3.4

years. Therefore, standards-compliant lamps will not occupy all IRL sockets until about 2015.

For this reason, the residential standards-case market-share matrix, representing the percentage

of sockets occupied by specific IRL, is give n in 2015 and 2042. Because the longest-lived

commercial IRL in the base case has a service life of 1.7 years, the commercial standards-case

market-share matrix is given in 2013 and 2042. Table 10.57 describes the inputs to the base case

and standards-case IRL market-share matrices for the commercial and residential sectors.

Table 10.58 displays the commercial standards-case market-share matrix for the Shift,

Product Substitution scenario. As discussed ear lier, in the base case, the commercial IRL

market is composed mostly of halogen lamps. At TSL1 halogen IRL are no longer standardscompliant and consumers purchasing halogen-ty pe IRL purchase improved halogen technology.

Since these matrices represent the Shift scenar io, those consumers already purchasing efficient

lamp products shift to purchase even more effi cient ones. (In the Roll -up scenario, consumers

already purchasing standards-compliant lamps continue to purchase products at the same

efficiency level. Table 10.60 displays the Roll-up, No Product Substitution scenario.) At TSL2

only long-life HIR and improved halogen lamps with a reduced-wattage can be sold. At TSL3

only HIR lamps are standards-compliant. TSL4 and TSL5 allow only the most efficient HIR

lamps. In the commercial sector, DOE assumed th at all institutions wish ing to convert to R-CFL

given its shortcomings (such as lower color qual ity) do so before 2012. Therefore, there is no

additional movement to R-CFL in response to standards.

Table 10.59 displays the residential standards-case market-share matrix for the Shift,

Product Substitution scenario. As discussed earlie r, DOE assumes that the entire residential

market purchases halogen IRL in the base case. At all subsequent TSLs, consumers usually

choose the least costly standards- compliant lamp. For the residential sector, DOE incorporated

additional movement to R-CFL. DOE calculate d simple payback periods comparing R-CFL to

the baseline halogen and R-CFL to the higher-effi ciency lamp designs. It used these payback

period calculations to determine incremental market penetrations. DOE assumes that some

consumers choose to purchase the less efficient 65W BR lamp, which is exempted from

standards, because of the difference in price. At TSL1, almost the entire residential market is

composed of improved halogen IRL, with a sm all portion purchasing re flector CFL or 65W BR

lamps. At TSL2, consumers start to shift to HIR lamps, so that at TSL3 the majority residential

market is purchasing HIR technology. At TSL4 , the residential IRL market is composed of

predominantly improved HIR lamps. TSL5 represents a “max-tech” HIR lamp, which has a

further improved reflective coating, IR coating, or filament design.

## 1 0.5 RESULTS



## The following sections show the shipments fo recasts for the various TSLs for GSFL and

IRL.

10.5 .1 General Service Fluorescent Lamps

10.5.1 .1 Shipments Forecasts: Base and Standards-Cases



## Figure 10.5.1 through Figure 10.5.6 present the shipments forecasts for the base case and

standards-cases for 4-foot medium bipin, 8-f oot single pin slimline, 8-foot recessed double

## 10-87 contact HO, 4-foot T5 standard output and high out put lamps in the Existi ng Technologies, Shift,

High Expertise Scenario and the Emerging T echnologies, Roll-up, Market-Segment Based

expertise scenario. These reflect th e upper- and lower-bound energy scenarios.

Quantities of lamp shipments depend on the occurrence of the lamp purchasing events:

lamp failure, ballast failure, ballast retrofit, and new construction. As discussed earlier, instead

of using each particular lamp design’s individual lifetime to time lamp replacements, DOE uses

an average lifetime for each analyzed lamp type. For this reason, the ra te of lamp replacement

does not change between the Sh ift and Roll-up, High and Market Segment-Based expertise

standards-case scenarios. In addition, because ba llast lifetime does not cha nge, the rate of ballast

failure is also the same in both scenarios. Since th e ballast retrofit rate is an input external to the

market-share matrices, the rate of occurrence of ba llast retrofits are the same for both scenarios.

Using the Shift or Roll-up scenario and High or Market Segment-Based expertise scenario does

affect the average lumen output of the lamp-a nd-ballast systems shipped, and therefore the

quantities of systems shipped due to renovation, fixture replacement, and new construction.

However, these market segments compose a fairly small portion of overall lamp shipments.

Therefore, though presented separately in the fo llowing tables when di fferent, the upper- and

lower-bound scenarios can result in similar quanti ties of shipments for all GSFL lamp types.

As seen in Figure 10.5.1 and Figure 10.5.2 , the standards-case for ecasts of 4-foot medium

bipin lamps experience similar trends as the base cas e, though at modified rates. In both the base

case and standards-case, the shipments forecast depicts a decrease in shipments of 4-foot T12

medium bipin systems, as only 10 percent of th ese retiring systems are replaced with the same

system. This trend is matched by a corresponding increase in shipments of 4-foot T8 medium

bipin systems due to their replacement of T12 systems, an increasing number of lamps per home,

and growth in lumen demand in the commercial s ector. Specifically, 4-foot T8 medium bipin

shipments increase because they replace 80 percen t of 8-foot T12 single pin slimline systems.

Additionally, with increasing trial standard levels, the early retrofit rates of 4-foot T12 medium

bipin systems in the commercial sector increase. In the residential se ctor, at higher TSLs a

greater portion of consumers replace their retired T12 systems with T8 systems; consequently, a

greater proportion of residential shipments are T8 s as opposed to T12s at higher TSLs. Because

4-foot T12 medium bipin and 8-foot T12 si ngle pin slimline lamps are no longer standardscompliant at EL4 and EL5, these systems are automatically retrofitted upon lamp failure (i.e.,

there are no T12 lamp shipments at these levels). Both these voluntary retrofits and standardinduced retrofits increase shipments of 4-foot T8 medium bipin lamps and decrease shipments of

4-foot T12 medium bipin lamps.

Forecasts (Emerging Technologies, Roll-up, Ma rket Segment-Based Expertise Scenario)



## As seen in Figure 10.5.3 , the standards-case forecasts of 8-foot single pin slimline lamps

experience similar trends as the base case, though at modified rates. In both the base case and

standards-case, the shipment forecast depicts a d ecrease in shipments of 8-foot T12 single pin

slimline lamps, as only 10 percent of retiring 8- foot T12 single pin slimline magnetic systems are

replaced with 8-foot T12 electronic systems. Initially, this trend is matched by a corresponding

increase in shipments of 8-foot T8 single pin slimline lamps due to the replacement of 10 percent

of 8-foot T12 single pin slimline systems with 8- foot T8 single pin slimline systems. However,

further into the analysis period, the stock of 8-foot 12 systems d eclines such that there are not

enough retiring T12 systems each year for T8 systems to replace and continue positive shipment

growth. Thus, around 2020—the precise year vari es by TSL, 8-foot T8 shipments peak and

begin to fall. Additionally, as with 4-foot medium bipin systems, the early retrofit rates of 8-foot

T12 single pin slimline systems increase with in creasingly TSLs. Because 8-foot T12 single pin

slimline lamps are no longer standards-compliant at TSL4 and TSL5, these systems are

automatically retrofitted upon lamp failure (i.e., th ere are no T12 lamp shipme nts at these TSLs).

There is no difference between the upper- and lower-bound scenarios prim arily because 8-foot

10-89

## single pin slimline lamps are not modeled to se rvice fixture replacement, renovation, and new

construction needs, and because average lifetime does not vary by scenario.

## Figure 10.5.3 Eight-Foot Single Pin Slimline Base Case and Standards-Case Shipments

Forecasts (Existing Technologies , Shift, High Expertise and Emerging Technologies, Rollup, Market Segment-Based Expertise Scenarios)



## As seen in Figure 10.5.4 , the standards-case shipment forecasts of 8-foot recessed double

contact HO lamps are identical to the base case at TSL1, TSL2, and TSL3. The only difference

between the base case and these standards levels is that higher efficacy lamps are being shipped

in the standards-cases. However, because 8-foot T12 recessed double contact HO lamps are no

longer standards-compliant at EL4 and EL5, th ese systems are automa tically retrofitted upon

lamp failure to 8-foot T8 recessed double cont act HO systems (i.e., ther e are no shipments at

these TSLs). These ballast retrofits and la mp replacements are a one-to-one replacement,

resulting in approximately same quantity of T8 shipments in the standards-case as T12 shipments

in the base case. They are not exactly the sa me because 8-foot RDC HO T8 lamps have longer

lifetimes their T12 counterparts. There is no difference between the upper- and lower-bound

scenarios primarily because 8-f oot recessed double contact HO lamps are not modeled to service

fixture replacement, renovation, and new construction needs.

base case forecasts of 4-foot T5 MiniBP sta ndard output and high output lamps. These two

product classes experience similar trends as the base case at slightly modified rates. This effect

is largely due to the fact that DOE does not directly assume additional shifts to or from these

product classes in the standards-case.

10.5. 1.2 Cumulative Shipments Impacts (2012 – 2042)



## Table 10.62 through Table 10.69 show the cumulative shipments impacts from 2012 to

2042 caused by each of the five standards-cases c onsidered for 4-foot medium bipin, 8-foot

single pin slimline, 8-foot recessed double contac t HO, and 4-foot T5 standard output and high

output lamps under the Existing Technologies, Shif t, High expertise and Emerging Technologies,

Roll-up, Market Segment-Based expertise scenario s. As discussed earlier , quantities of lamp

shipments in the standards-case are based on lamp replacement rates, ballast replacement rates,

shipments due to new construction, and ballast retr ofit rates. However, b ecause all lamps within

a particular product class are assu med to have the same lifetime, lamp replacement rates in the

base case and standards-case are equivalent. In addition, because the ballast lifetime never varies

within a particular market sector, ballast replac ement rates are equivalent in the base case and

standards-case. The only aspects that do vary are the shipments due to new construction

(because average lumen outputs per system vary),a nd ballast retrofit rate s (for 4-foot medium

bipin and 8-foot single pin slimline systems).

Table 10.62 and Table 10.63 and show that as ballast retrofit rates increase with standard

levels, 4-foot medium bipin cumulative lamp ship ments generally increase as well. With higher

10-93

## 10-94 retrofit rates, consumers are discarding their ex isting, working lamps and therefore must make

more total lamp purchases. However, the average lumen output per system affects these

cumulative shipments as well. For example, as seen in Table 10.62 a high average lumen output

per lamp system at TSL5 results in fewer shipme nts due to new construction, and therefore fewer

cumulative shipments.

the technology mix of shipments. Table 10.64 and Table 10.65 present cumulative shipments

impacts for both the lower- and uppe r-bound scenarios. As seen in Table 10.64 , cumulative

impacts decrease with increasing trial standard le vels because of the large number of 8-foot

single pin slimline systems that experience an earl y turnover to 4-foot medium bipin systems.

Cumulative impacts decrease at TSL4 and TSL5 for 8-foot recessed double contact systems

when standards phase out T12 lamps of this type . In turn, while the shipment model in the

industrial sector does not incorporate retrofits, cumulative sh ipment impacts for 8-foot recessed

double contact HO lamps exist because of there is a ballast lifetime difference between T8 and

T12 systems of this product class, resu lting in the cumulative impacts show in Table 10.65

.

## As shown in Table 10.66 and Table 10.69 , cumulative impacts on 4-foot T5 MiniBP

standard and high output lamps are approximately equivalent for the Existing Technologies,

Shift, High expertise and Emerging Technologies , Roll-up, Market Segment-Based scenarios

because average lumen output increases only sligh tly in the Shift scenar io. Impacts are roughly

flat until TSL5 when a higher average lumen output causes fewer lamps to be shipped to service

lumen demand. Similar to other product classes, at TSL4 and TSL5, shipment impacts decrease

due to the higher average system lumen output of these lamps.

## 10.5.2 Incandescent Reflector Lamps



## This section presents shipment results for th e IRL shipment scenarios. The results for the

10-percent lumen increase sensitivity scenarios are presented in Appendix 10B.

## 10.5.2.1 Shipments Forecasts: Base and Standards-Cases



## Figure 10.5.7 and Figure 10.5.8 present shipments forecasts for the base case and

standards-cases for IRL. These two shipment forecasts can be characterized as the upper- and

lower-bound energy savings scenarios.

Figure 10.5.7 displays the IRL base case in the Emerging Technologies scenario and the

standards-case shipment forecasts for the Roll- up, no product substitution scenario. At TSL1,

consumers who in the base case purchase haloge n IRL (some of which are 2,500 hours), instead

purchase improved halogen IRL (with a lifetim e of 3,000 hours) in the standards-case.

Similarly, at TSL2 all consumers purchase HIR IRL with a lifetime of 3,000 hours. Because the

lifetimes of the TSL1 and TSL2 lamp designs are longer than those of the base case lamps, lamp

replacements occur less frequently, thereby causing a reduction in sh ipments. The longer

lifetimes (4,000 hours) of improved halogen lamps designs at TSL3 cause an even further

reduction in IRL shipments. Similar trends occu r at TSL4 and TSL5 as the lamps shipped at

these standard levels are 4,000 hours a nd 4,200 hours in lifetime, respectively..

Shift, product substitution standard s-case scenario. Again, shipments in the standards-cases are

lower than the base case shipments due to the integration of longer lifetime lamp designs.

## Table 10.70 and Table 10.71 present cumulative shipment impacts the Existing

Technologies, Shift, product s ubstitution scenario and the Emerging Technologies, Roll-up, no

product substitution scenario, respectively. Shipme nt impacts are associated with the increased

lifetime of standards-case lamps. The longer the lifetime of standa rds-case lamps, the greater the

impact on shipments due to fewer lamps needing to be replaced each year.
