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

REZ-2S54-35M (176248) is the Philips Advance T5 Fluorescent Ballast. This model is a replacement ballast for the matching fluorescent lamp circuit. Select it from the lamp schedule inside the existing fixture. The listed lamp configuration is 2 X F54T5HO, which should be checked as a complete lamp-and-count combination. Its specified starting method is programmed start; compare it with the existing circuit rather than relying on the housing dimensions alone. Ballast factor 1 is one comparison point for retaining the intended lamp output in this fixture.

The 120V AC supply specification must match the circuit serving this model. Compare length 16.70 in., width 1.18 in., height 1.00 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.
