Philips Advance Metal Halide Ballast - 70W | 120/208/240/277V AC | Pulse Start

Philips Advance Metal Halide Ballast (71A5292-500D). For maintenance of a fluorescent troffer or strip, this model must match the fixture’s supported lamp configuration. The 70W MH operating configuration distinguishes this ballast from versions intended for a different lamp count. Its specified starting method is pulse start; compare it with the existing circuit rather than relying on the housing dimensions alone.

The 120/208/240/277V AC supply specification must match the circuit serving this model. This version lists length 3.90 in., width 2.80 in., height 2.75 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.
