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

ICN-2S54-90CN-35M (498394) is the Philips Advance 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 1-2 X F54T5HO operating configuration distinguishes this ballast from versions intended for a different lamp count. 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.

Use the 120-277V AC version only where the supply and control arrangement suit its electrical specification. Compare length 9.5 in., width 1.3 in., height 1.0 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.
