Lumatek Electronic Ballast 600 W 240V

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)
