These energy-efficient ballasts are the coolest on the market, with extremely cool and silent operation. Their heat-dispersing fins help to eliminate the trapped heat, and attached mounting plates allow these ballasts to operate either horizontally or vertically, making them ideal for all setup situations.
Rubber feet reduce noise by preventing vibration. All models include a built-in surge protector, run both MH and HPS lamps, and are compatible with Type S reflector. The exclusive ability to dim these ballasts allows you to reduce your amps and lower your electricity costs!
