Prism Lighting Science 315w Ceramic Metal Halide CMH Remote Ballast 120/240v Structure The Hanna GroLine Waterproof HydroponicA 315W ceramic metal halide ballast for CMH lamps The ballast drives a 315W CMH lamp on a low frequency square wave, the waveform Philips CDM bulbs need to hit their rated PAR output. It runs on variable 120 or 240V, drawing 343W with a power factor above 0. 95 and THD under 15%. Prism tuned it to match Philips CDM lamp specs, so it is a lower cost stand in with the same core functionality. Growers mount it remotely, away from the canopy, so its heat
