700W CMH (dual 350) low frequency square wave dimming ballast utilizes Fuzzy Logic technology. The patent technology can keep lumen maintenance rate higher than 95% at 30,000 hours and maintain the initial spectrum. It can ignite bulbs more than 100 feet away. With LamPal® technology, this ballast can work with 150W, 210W, 315W and 350W CMH/HPS/MH lamps. The remote control allows you to turn on/off the light and select any of the power outputs: 300W, 420W, 630W and 700W. You can use the 0-10V module (optional) to adjust power output from 300W to 700W continuously.
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.
