variability in lamp manufacturing.

Those values would help the

Department evaluate current and

proposed approaches to account for

measurement uncertainty.

NEMA, speaking for manufacturers,

claims that if the Department requires

all incandescent lamps to be tested or

measured for compliance at 120 volts

regardless of rated voltage, that would

render obsolete lamps designed for

operation at other than 120 volts. This

is because lamps that are designed for

operation at voltages greater than 120

volts may not meet the minimum

efficacy standard when tested at 120

volts; lamps that are tested at 120 volts

and found to comply with the energy

efficiency standards will have a shorter

life when operated in regions where line

voltages are greater than 120 volts.

According to NEMA, for those regions,

an inevitable consequence of a rule

requiring compliance testing at 120

volts would be the virtual elimination of

existing lamp products designed for use

where line voltages are greater than 120

volts. NEMA also contends that "when

EPACT was enacted, Congress and the

lamp industry understood that

compliance with energy efficacy

standards would be determined at an

incandescent reflector lamp's design

voltage."

The statute does not directly address

whether testing and compliance of

incandescent lamps must be fixed at one

voltage or must be at the rated voltage.

But section 324(4)(2)(C)(i) of the EPCA

states that labeling "shall be based on

performance when operated at 120 volts

input, regardless of the rated lamp

voltage." Consistent with this language,

it is at least arguable that testing and

compliance of all incandescent lamps

must also be at 120 volts. If the statute

is read as not containing such a

requirement,-however, the following are

possible alternatives to determining

compliance of all lamps at 120 volts: (1)

Incandescent lamps should be tested

and comply at the rated voltage, i.e., the

voltage of intended use; (2) establish

several voltage classes with testing and

compliance at a specific voltage in each

class; or (3) in addition to 1 or 2, take

steps (such as labeling requirements, for

example) to assure that lamps are sold

only for use at their rated voltage. The

Department is seeking discussion of (1)

Its authority to permit or require testing

at voltages other than 120 volts, (2) the

foregoing three alternatives, and (3) any

other alternatives which relate to the

issue of the voltage level(s) at which

incandescent lamps should be tested

and measured for compliance.

A NEMA comment requests that the

Department treat a family of fluorescent

lamps of different colors but with the

same wattage and light output as a basic

model. Some lamp manufacturers also

claimed that it was unclear whether a

basic model of lamp is an individual

lamp type or a family of lamps with

similar lumen output and other

characteristics. This issue is critical to

manufacturers because they want to

assure themselves that they will not test

more lamps than are necessary. The

Department's interim final test

procedures for lamps require testing of

each "basic model," and in essence

define basic model for lamps as

consisting of "a given type" or "class"

of lamps that have "photometric and

electrical characteristics, including

lumens per watt and Color Rendering

Index (CRI), which are essentially

identical. The Department seeks

discussion on whether manufacturers

believe an alternative definition is

appropriate, and, if so, why and what

alternatives they would propose.

NEMA suggested in its comments that

the statutory limitation to a "voltage

range at least partially within 115 to 130

volts, could unintentionally create a

potential for evading the standard for

incandescent lamps." Commenters

suggested that there may be some

manufacturers who are preparing to

build 114V lamps, and that the

Department should clarify or expand

what is included in the voltage range.

To the extent that the "voltage range" of

a product such as a 114 volt lamp "lies

at least partially within 115 and 130

volts," section 321(30)(C)(ii) of EPCA,

the statue clearly covers that product.

Standards and test procedures,

therefore, would clearly apply to the

product. Possible alternatives, however,

are (1) To declare that a lamp is covered

if its intended use is in the 115-130V

range or (2) to expand the voltage range

from 100 to 150 volts. Workshop

participants should be prepared to

discuss the need and means for further

-addressing this issue.

The definition of colored lamp in the

proposed rule on lamp definitions

provides two alternatives, (1) A CRI

value less than 30 for fluorescent lamps

or CRI values below 50 for incandescent

lamps, or (2) a lamp color correlated

temperature either below 2,500 °K or

above 7,000 °K. Other possible

alternatives suggested in the comments

are to: (3) use excitation purity which is

defined as the ratio of two collinear

distances on the chromaticity diagram,

(4) raise the CRI for fluorescent lamps to

40, or (5) base the exemption for colored

lamp on the lamp application. The

Department is seeking information and

data on the workability and practicality

of these alternatives.

4. Public Meeting Procedure

The meeting will be informal but, will

be transcribed by a court reporter.

Participants will receive a copy of the

Federal Register notice of the Interim

Final Rule at the meeting. 59 FR 49468.

Copies of the Interim Final Rule, the

Notice of Proposed Rulemaking on

definitions, and this notice are available

in the DOE public reading room. A copy

of the meeting transcript will be

available in the DOE public reading

room approximately 10 days after the

workshop.
