Sylvania T8 Fluorescent Ballast (QHE2x32T8/347 ISL-SC (49473)). For maintenance of a fluorescent troffer or strip, this model must match the fixture’s supported lamp configuration. The 2 X F32T8 operating configuration distinguishes this ballast from versions intended for a different lamp count. The instant start starting arrangement is part of the compatibility check for the installed lamp circuit. When comparing replacements, note the 0.78 ballast factor as well as the lamp and supply ratings.

Buying tip: Match the lamp designation, number of lamps and supply voltage to the existing ballast.
