  • (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.
