Hydrofarm Quantum QT400 Dimmable Ballast, 400W, 400 W

Quantum 400W Dimmable BallastThe 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. Run at 100%, 75% or 50% power (400W runs at 100% and 75%)Strike both metal halide and high pressure sodium bulbsAccepts 120V/240V with no wiring needed (both cords included); 208V-configurable with electrician assistanceAccepts 50 Hz to 60 Hz with no extra wiring neededRuns 15% cooler than other digital ballasts on the marketHas a continuous power factor of 99%The most stable output frequency of any ballastHigher lumen output than magnetic ballastsCan run efficiently on generators without flickeringResin sealed circuit board for high humidity installationsCan easily be used in conjunction with lighting controllers and flip boxesThe Quantum Dimmable Ballast brings quality, efficiency, and high intensity illumination to your garden.
