The bulb is pricey at 99.95, but it doesn't require a ballast.
The BritePro Lamp is a 85 watt self-ballasted, 77% less energy used and full daylight spectrum lighting. These lamps are appropriate for use in any application where true color rendering is important.
New technological electronic ballasts provide for instant, flicker free illumination compared to early designed magnetic ballasts. BritePro lamps have a rated life of 10,000 hours before intensity may diminish. The heat generated is far less than any H.P.S. (High Pressure Sodium) or MH (Metal Halide) light source. Working temperature is so low that you can actually touch the bulb while it is on without injury.
The BritePro Lamp is available in RED Spectrum (2700K) or FULL Spectrum (6400K).
