Doubled Ended Ballasts are built to power double-ended grow lights. Through the use of digital ballast technology, our offerings of DE Ballasts can power both 1000w and 750w DE lamps. Double Ended lighting has taken the growing world by storm over the past few years, thanks to their …improved efficiency, output, and applications in commercial settings. DE bulb construction allowed for better flow of electricity through the entire fixture, driven by digital ballasts. This gives your plants more light energy per watt than ever before in an HID fixture, as well as better bulb life and turbo-power options for even more output.
