What are the ballast efficiency values for compliance?
Section 324(e) of EISA 2007 requires specific efficiency values for the various types of covered metal halide ballasts. These requirements, codified at 42 U.S.C. 6295(hh), are as follows: “(hh) METAL HALIDE LAMP FIXTURES.— “(1) STANDARDS.— “(A) IN GENERAL.—Subject to subparagraphs (B) and (C), metal halide lamp fixtures designed to be operated with lamps rated greater than or equal to 150 watts but less than or equal to 500 watts shall contain— “(i) a pulse-start metal halide ballast with a minimum ballast efficiency of 88 percent; “(ii) a magnetic probe-start ballast with a minimum ballast efficiency of 94 percent; or “(iii) a nonpulse-start electronic ballast with— “(I) a minimum ballast efficiency of 92 percent for wattages greater than 250 watts; and “(II) a minimum ballast efficiency of 90 percent for wattages less than or equal to 250 watts Section 324(e) of EISA 2007 also establishes certain exclusions from the regulation. These are as follows: “(B) EXCLUSIONS.—The standards est
