Quantum 400W Dimmable Ballast
The Quantum Dimmable Ballast brings quality, efficiency, and high intensity illumination to your garden. With a Power Factor of 99.9%—a highly stable output frequency—the Quantum Dimmable ballast lets you run your lamps at the strength you need allowing you to control your light spread. Rigorously engineered, it features a resin cased circuit board with a sealed bearing fan so it will run cooler than any other ballast and it’s been tested to withstand the extreme atmospheric conditions of virtually any growing environment. The Quantum Dimmable Ballast is silent, generator-ready, efficient, and cool-running—this is one cool ballast.
NOTE: The Quantum QT400 ballast is designed to operate single-ended lamps only, and cannot run double-ended (DE) lamps.
