Product Description

400W knob dimming CMH low frequency square wave digital ballast utilizes Fuzzy Logic 4th Generation ballast technology. The patent technology can keep lumen maintenance rate higher than 95% at 30,000 hours and maintain the initial spectrum. It can ignite lamps more than 100 feet away. With Lamp technology, this ballast can work with 150W, 210W, 315W, 350W, and 400W CMH/HPS/MH lamps. You can use the knob to turn on/off the light and to output 150W, 210W, 315W, 350W and 400W.

When lamp power is decreased, it saves energy and shifts light spectrum to more blue light for veggies; when lamp power is increased, it outputs more strong light and shifts light spectrum to more red light to grow more and bigger flowers and shorten the growing circle.
