Halco M135/400CWA/4T/K 400W Metal Halide Ballast M135 4T Pulse Start Kit (55162)

This 4-tap electromagnetic ballast kit powers a single 400-watt pulse start metal halide lamp carrying ANSI code M135 or M155. The constant wattage autotransformer (CWA) circuit holds lamp output steady across supply variations, and four voltage taps let the installer match the kit to the line voltage on site — 120V/208V/240V/277V. The kit ships with the core-and-coil ballast and the components needed to complete a fixture retrofit or replacement.
