Philips Advance Fluorescent Ballast - 18W | 120-277V AC | Programmed Start

ICF-2S18-H1-LD-35M is the Philips Advance Fluorescent Ballast. For maintenance of a fluorescent troffer or strip, this model must match the fixture’s supported lamp configuration. The 1 or 2 X 18W CFL 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.

Plan the electrical connection around this model’s 120-277V AC rating. This version lists length 4.60 in., width 2.40 in., height 1.00 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.
