Sylvania T5 Fluorescent Ballast - 120-277V AC | Programmed Start

The Sylvania T5 Fluorescent Ballast, model QHE2x54T5/HO/UNV/PSN (51470), is the component described here. For maintenance of a fluorescent troffer or strip, this model must match the fixture’s supported lamp configuration. It is specified for 2 X F54T5HO; preserve the required lamp type and quantity when selecting the ballast. This is the programmed start version, so the fixture wiring and lampholder arrangement must suit that starting method. The listed ballast factor is 1, which is relevant when comparing the output of the same lamps on different compatible ballasts.

Check the installation supply against the 120-277V AC rating for this version before ordering. This version lists length 14.17 in., width 1.18 in., height 0.87 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.
