315w Digital Ballast, Operates all Single-Ended and Double-Ended 315w CMH Lamps Only, 120-277VAC.


1.With 30% more lumens and a higher PAR/PPF output than a standard ballast, maximizing the PAR output of your Ceramic Metal Halide lamps.
315W CMH digital ballast actually uses far less energy too. Making it more economic to run and giving higher yields than previously possible.
2. Can be used with both high-pressure sodium or metal halide lamps.
3. Ultra-Safety: fast start-up facility and generates much less heat, protection against Short Circuit, Power Surge, Ignition Failure, Overheat, End-of Bulb-Life.
4. Silent operation-Silent running and cool operating temperature.
5. Ballast and bulb can be used with any type of 315W Euro reflector.
6. White metal shell, higher insulation protection, and lighter weight.


We are the most powerful and reliable digital ballast manufacture.
315W CMH ballast is suitable for 315W CMH Grow Light Kit/Fixture with 3000K and 4000K color temperature lamps.
Using for Hydroponics/greenhouse/indoor plants growth.
