3A.4 ENERGY INDEPENDENCE AND SECURITY ACT OF 2007

On December 19, 2007, the President signed into law the Energy Independence and Security Act 

of 2007 (EISA 2007) (P.L. 110-140). This legislation amended certain aspects of EPCA, 

including, in particular, the potential amendment of existing testing requirements for fluorescent 

lamp ballasts (see section 310 of EISA 2007) and addition of mandatory efficiency standards for 

metal halide lamp fixtures (see section 324 of EISA 2007). Among other things, the new 

standard for metal halide lamp fixtures establishes requirements for the efficiency of the ballasts 

installed in metal halide lamp fixtures. DOE is aware that some companies that produce 

fluorescent lamp ballasts may also manufacture metal halide lamp ballasts and fixtures; 

therefore, the entirety of EISA 2007 section 324 is included here for reference. 

SEC. 310. STANDBY MODE. 

Section 325 of the Energy Policy and Conservation Act (42 U.S.C. 6295) is amended— 

(1) in subsection (u)— 

(A) by striking paragraphs (2), (3), and (4); and 

(B) by redesignating paragraphs (5) and (6) as paragraphs (2) and (3), 

respectively;

`(ii) OFF MODE- The term `off mode' means the condition in which an 

energy-using product— 
3A-11

`(I) is connected to a main power source; and 

`(II) is not providing any standby or active mode function. 

`(iii) STANDBY MODE- The term `standby mode' means the condition in 

which an energy-using product— 

`(I) is connected to a main power source; and 

`(II) offers 1 or more of the following user-oriented or protective 

functions: 

`(aa) To facilitate the activation or deactivation of other 

functions (including active mode) by remote switch 

(including remote control), internal sensor, or timer. 

`(bb) Continuous functions, including information or status 

displays (including clocks) or sensor-based functions. 

`(B) AMENDED DEFINITIONS- The Secretary may, by rule, amend the

versions of Standards 62301 and 62087 of the International Electrotechnical 

Commission. 

`(2) TEST PROCEDURES- 

`(A) IN GENERAL- Test procedures for all covered products shall be amended 

pursuant to section 323 to include standby mode and off mode energy 

consumption, taking into consideration the most current versions of Standards 

62301 and 62087 of the International Electrotechnical Commission, with such 

energy consumption integrated into the overall energy efficiency, energy 

consumption, or other energy descriptor for each covered product, unless the 

Secretary determines that— 

`(i) the current test procedures for a covered product already fully 

account for and incorporate the standby mode and off mode energy 

consumption of the covered product; or 

`(ii) such an integrated test procedure is technically infeasible for a 

particular covered product, in which case the Secretary shall prescribe a 

separate standby mode and off mode energy use test procedure for the 

covered product, if technically feasible

. 

`(B) DEADLINES- The test procedure amendments required by subparagraph (A) 

shall be prescribed in a final rule no later than the following dates: 
3A-12

(a) DEFINITIONS.-- Section 321 of the Energy Policy and Conservation Act (42 U.S.C. 6291) 

(as amended by section 322(a)(2)) is amended by adding at the end the following: 

`(58) BALLAST.-- The term `ballast' means a device used with an electric discharge lamp 

to obtain necessary circuit conditions (voltage, current, and waveform) for starting and 

operating. 
3A-13

`(59) BALLAST EFFICIENCY.--

`(A) IN GENERAL.-- The term `ballast efficiency' means, in the case of a high 

intensity discharge fixture, the efficiency of a lamp and ballast combination, 

expressed as a percentage, and calculated in accordance with the following formula: 

Efficiency = Pout/Pin. 

`(B) EFFICIENCY FORMULA.-- For the purpose of subparagraph (A)--

`(i) Pout shall equal the measured operating lamp wattage;

`(ii) Pin shall equal the measured operating input wattage; 

`(iii) the lamp, and the capacitor when the capacitor is provided, shall constitute 

a nominal system in accordance with the ANSI Standard C78.43-2004; 

`(iv) for ballasts with a frequency of 60 Hz, Pin and Pout shall be measured after 

lamps have been stabilized according to section 4.4 of ANSI Standard C82.6-2005 

using a wattmeter with accuracy specified in section 4.5 of ANSI Standard C82.6-

2005; and 

`(v) for ballasts with a frequency greater than 60 Hz, Pin and Pout shall have a 

basic accuracy of ±0.5 percent at the higher of--

`(I) 3 times the output operating frequency of the ballast; or 

`(II) 2 kHz for ballast with a frequency greater than 60 Hz. 

`(C) MODIFICATION.-- The Secretary may, by rule, modify the definition of `ballast 

efficiency' if the Secretary determines that the modification is necessary or 

appropriate to carry out the purposes of this Act. 

`(60) ELECTRONIC BALLAST.-- The term `electronic ballast' means a device that uses 

semiconductors as the primary means to control lamp starting and operation. 

`(61) GENERAL LIGHTING APPLICATION.-- The term `general lighting application' 

means lighting that provides an interior or exterior area with overall illumination. 

`(62) METAL HALIDE BALLAST.-- The term `metal halide ballast' means a ballast used 

to start and operate metal halide lamps. 

`(63) METAL HALIDE LAMP.-- The term `metal halide lamp' means a high intensity 

discharge lamp in which the major portion of the light is produced by radiation of metal 

halides and their products of dissociation, possibly in combination with metallic vapors. 
3A-14

`(64) METAL HALIDE LAMP FIXTURE.-- The term `metal halide lamp fixture' means a 

light fixture for general lighting application designed to be operated with a metal halide 

lamp and a ballast for a metal halide lamp. 

`(65) PROBE-START METAL HALIDE BALLAST.-- The term `probe-start metal halide 

ballast' means a ballast that--

`(A) starts a probe-start metal halide lamp that contains a third starting electrode 

(probe) in the arc tube; and 

`(B) does not generally contain an igniter but instead starts lamps with high ballast 

open circuit voltage. 

`(66) PULSE-START METAL HALIDE BALLAST.--

`(A) IN GENERAL.-- The term `pulse-start metal halide ballast' means an electronic 

or electromagnetic ballast that starts a pulse-start metal halide lamp with high 

voltage pulses. 

`(B) STARTING PROCESS.-- For the purpose of subparagraph (A)--

`(i) lamps shall be started by first providing a high voltage pulse for ionization of 

the gas to produce a glow discharge; and 

`(ii) to complete the starting process, power shall be provided by the ballast to 

sustain the discharge through the glow-to-arc transition.'. 

(b) COVERAGE.-- Section 322(a) of the Energy Policy and Conservation Act (42 U.S.C. 

6292(a)) is amended--

(1) by redesignating paragraph (19) as paragraph (20); and 

(2) by inserting after paragraph (18) the following: 

`(19) Metal halide lamp fixtures.'. 

(c) TEST PROCEDURES.-- Section 323(b) of the Energy Policy and Conservation Act (42 

U.S.C. 6293(b)) (as amended by section 301(b)) is amended by adding at the end the following: 

`(18) METAL HALIDE LAMP BALLASTS.-- Test procedures for metal halide lamp 

ballasts shall be based on ANSI Standard C82.6-2005, entitled `Ballasts for High 

Intensity Discharge Lamps--Method of Measurement'.'. 

(d) LABELING.-- Section 324(a)(2) of the Energy Policy and Conservation Act (42 U.S.C. 

6294(a)(2)) is amended--

(1) by redesignating subparagraphs (C) through (G) as subparagraphs (D) through (H), 

respectively; and
3A-15

(2) by inserting after subparagraph (B) the following: 

`(C) METAL HALIDE LAMP FIXTURES.--

applicable to the covered product specified in section 322(a)(19) and to which 

standards are applicable under section 325. 

`(ii) LABELING.-- The rules shall provide that the labeling of any metal halide 

lamp fixture manufactured on or after the later of January 1, 2009, or the date 

that is 270 days after the date of enactment of this subparagraph, shall indicate 

conspicuously, in a manner prescribed by the Commission under subsection (b)
