LumatekŪ Digital Ballasts
From increased efficiency to increased lumen output, digital ballasts are the next big leap in indoor gardening technology. Compared to traditional magnetic ballasts, they deliver more power from outlet to lamp, provide light at a far more stable level, start up faster (full light in under one minute!) and operate silently.
These low-weight ballasts also produce less heat, and short-circuits trigger a power cutoff as a safety measure. Dial-A-Watt™ technology adjusts the power level for a previously unseen level of versatility. Both the input and output power of the ballast are changed when different settings are selected, so when the dial is set to 600 W on a 1,000-W ballast, it performs like a regular 600-W ballast. This great feature allows you to use a 400-W MH lamp for the vegetative phase of growth, then switch over to a 600-W HPS lamp when it's time to bloom.
