GrowBright’s 1000w Switchable ballast lets growers run both HPS and Metal Halide bulbs on with the same ballast. An aluminum enclosure keeps all internal components safe and secure while reducing both noise and increasing ventilation for longer fixture life. Both 120v and 240v inputs are accepted by the ballast, so you can run this on a household circuit or off of a commerical hookup. Pick up this ballast and power your 1000w HID bulbs to their fullest capacity. Grow Bigger – Grow Better – Grow Bright.
GrowBright Professional 1,000-Watt High-Pressure Sodium/Metal Halide Ballast in an Aluminium enclosure with 120-volt power cord (can also accept optional 240-volt power cord!)
