The Lumatek Electronic Ballast provides a stable light output and has a fast start-up. It reaches full brightness in under one minute whereas magnetic ballasts take longer. The Lumatek Electronic Ballast is completely silent and produces less heat than standard ballasts. This ballast has cut-off circuitry and allows for a longer bulb life. The Lumatek Electronic Ballast has a small compact design - the 600 watt 230 volt ballast weighs less than 3.75kg compared to heavier magnetic ballasts. This ballast can light both HPS and MH lamps.
