Philips Advance T8 Fluorescent Ballast - 347V AC | Dimmable | Programmed Rapid Start

GZT-2S32-SC-35M (109777) is the Philips Advance T8 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 F32T8, 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. When comparing replacements, note the 0.88 ballast factor as well as the lamp and supply ratings.

For electrical planning, 347V AC is the stated supply requirement for this model. Compare length 9.50 in., width 1.70 in., height 1.18 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.
