PUBLIC LAW 110–140—DEC. 19, 2007

dkrause on GSDDPC44 with PUBLAW

‘‘(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. ‘‘(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
