Ballasts

Coralvue^® electronic ballasts are an important energy-saving unit used for metal halide lamps. Its job is to fire the lamps and stabilize the operating current. This ballast can save energy by more than 30%. The ballast has a self-protected circuit, which is controlled automatically. If power is removed or lost from the ballast it will take approximately 7 minutes for the ballast to fire the lamp again. The ballasts are available in normal or dimmable. These ballasts will drive any 175w SE metal halide bulb or 150w DE (HQI) metal halide bulb.

More lumens generated per watt of electricity consumed - Lumatek™ ballasts have increased efficiency over magnetic ballasts. They lose fewer watts from the power supply to the lamp. This is a power factor of 95%+. The high frequency output results in low power loss  

Fast start-up - they reach full brightness quickly 
Small compact design 
Produce less heat  
Cut-off circuitry - cut off when a short is detected.
