Sylvania T8 Fluorescent Ballast - 120-277V AC | Instant Start

The Sylvania T8 Fluorescent Ballast, model QTP3x32T8/UNV-ISN-SC-B (49907), is the component described here. When servicing a socketed fluorescent fixture, compare this model against the lamp schedule and supply before ordering. The 3 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. The listed ballast factor is 0.88, which is relevant when comparing the output of the same lamps on different compatible ballasts.

This version is specified for 120-277V AC; that rating is part of the selection when replacing an existing fitting. This version lists length 9.50 in., width 1.68 in., height 1.18 in. Those measurements help check physical fit at the ballast compartment. 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.
