Philips Advance T5 Fluorescent Ballast - 120-277V AC | Programmed Start

ICN-2S54-90CT-35M (501676) is the Philips Advance T5 Fluorescent Ballast. When servicing a socketed fluorescent fixture, compare this model against the lamp schedule and supply before ordering. The 2 X F54T5HO operating configuration distinguishes this ballast from versions intended for a different lamp count. This is the programmed start version, so the fixture wiring and lampholder arrangement must suit that starting method. Ballast factor 1 is one comparison point for retaining the intended lamp output in this fixture.

For electrical planning, 120-277V AC is the stated supply requirement for this model. The listed body dimensions are length 14.17 in., width 1.18 in., height 1.06 in.; use them when checking the available space around 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.
