Philips Advance Metal Halide Ballast - 70W | 120V AC | Pulse Start

Philips Advance Metal Halide Ballast (71A5205-500DP (192757)). Use this model when the ballast in the fixture is specified for the same lamp type, lamp count and supply. The 70W MH operating configuration distinguishes this ballast from versions intended for a different lamp count. This is the pulse start version, so the fixture wiring and lampholder arrangement must suit that starting method.

Plan the electrical connection around this model’s 120V AC rating. For the ballast compartment layout, allow for the listed length 4.20 in., width 2.65 in., height 2.20 in. and the installation clearances required by its instructions. 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.
