Philips Advance T8 Fluorescent Ballast - 120-277V AC | Instant Start

Philips Advance T8 Fluorescent Ballast (QHE1x32T8/UNV ISN-SC (49851)). For maintenance of a fluorescent troffer or strip, this model must match the fixture’s supported lamp configuration. The 1 X F32T8 operating configuration distinguishes this ballast from versions intended for a different lamp count. This is the instant start version, so the fixture wiring and lampholder arrangement must suit that starting method. When comparing replacements, note the 0.88 ballast factor as well as the lamp and supply ratings.

Check the installation supply against the 120-277V AC rating for this version before ordering. Compare length 9.50 in., width 1.68 in., height 1.18 in. with the available space for the ballast compartment, especially when retaining an existing enclosure or shade. Follow the wiring diagram for this model when making the replacement connections.

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