Overview
The Current (GE) GEM175ML5AA3-5 is a magnetic core and coil HID distributor replacement kit designed for 175W metal halide lighting systems. This 5-Tap ballast operates on five standard line voltages — 120, 208, 240, 277, and 480V — making it a versatile drop-in replacement for a wide range of commercial and industrial fixtures. The CWA (Constant Wattage Autotransformer) circuit type ensures stable lamp performance across voltage fluctuations of ±10%. Compatible with M57 and H39 Mercury lamp types using probe start technology.
