Philips Advance T8 Fluorescent Ballast - 120-277V AC | Instant Start

The Philips Advance T8 Fluorescent Ballast, model IOPA-2P32-LWN-35M (107854), is the component described here. This model is a replacement ballast for the matching fluorescent lamp circuit. Select it from the lamp schedule inside the existing fixture. The 2 X F32T8 operating configuration distinguishes this ballast from versions intended for a different lamp count. The instant start starting arrangement is part of the compatibility check for the installed lamp circuit. When comparing replacements, note the 0.77 ballast factor as well as the lamp and supply ratings.

The 120-277V AC supply specification must match the circuit serving this model. This version lists length 9.50 in., width 1.30 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.
