Lumatek 400 watt 120/240 volt digital ballast
Lumatek 400 watt 120/240 volt digital ballast. From their increased efficiency to their increased lumen output, digital ballasts truly are the next big leap in indoor lighting technology. Compared to traditional magnetic ballasts, Lumatek Digital Ballasts lose less power from outlet to lamp, provide light at a far more stable level, start up faster (full light in under one minute!), and reduce the noise a system generates by running silently. These low-weight ballasts are internally RF-shielded to minimize electrical interference, they produce far less heat than their traditional counterparts, and short-circuits trigger a power cutoff as a safety measure. As if all that weren't enough, this 1000W/240V Lumatek Digital Ballast also lights both HPS and MH lamps for the ultimate in versatility! 15-foot RF-shielded power cord included with all ballasts. Universal lamp cord connection compatible with Sunlight Supply, Sunleaves, Hamilton, BWGS and other lighting manufacturers.
