Lumatek Electronic Ballasts 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 Completely silent Small compact design Produce less heat Cut-off circuitry - cut off when a short is detected. For ultimate safety Fully interchangeable - Lumatek ballasts can light both HPS and MH bulbs (excluding the 750W which is HPS only) NEW - A dimming knob has been added which will allow them to be set at 50/75/100% (only reduce the amount of light not the power usage). UNIQUE FEATURE! All Lumatek ballasts come wired with our standard female lamp cord receptacle that accepts our proprietary, patented male lame cord, making these units compatible with all Sun System reflectors. Purchase lamp cord with socket assembly separately. Lumatek lk6240 electronic ballast 600w 240v - dimmable 902540
