Growlite 1000w Digital Dimmable Ballast

Growlite 1000w Digital Dimmable Grow Light Ballast Specifications: Runs at 100%, 75% or 50% power, dimmable Compatible with both Metal Halide (MH) and High Pressure Sodium Bulbs (HPS) Accepts 120V or 240V Allows 50 hertz to 60 hertz All Growlite ballasts are tested before being packed Growlite ballasts run 15% cooler than other digital ballasts on the market Has a Power Factor of 99.9% The most stable output frequency of any ballast Higher lumen output than magnetic ballasts Light weight and care free Frequently Asked Questions of the Growlite 1000w Digital Ballast How does growlite avoid acoustic resonance? Two solutions to avoid acoustic resonance. A. Apply higher frequency (i.e. above 60KHz, below this would probably cause acoustic resonance) B. Apply low frequency (i.e. below 400Hz growlite ballasts run between 70-100 KHz.) Why is the growlite ballast square? Large amount of tests have proven that square PCB’s are most effective for heat dissipation. Why is the growlite ballast case potentially higher in external heat than other ballast? The cooling fin of the growlite ballast is lower and smaller than the leading brands, case temperature will be a little higher accordingly, but the temperature inside the growlite ballast is actually lower, this will extend the ballast life to other major brands. Can you apply a 600 watt lamp on our 1000 watt dimming ballast? We recommend using 1000W lamps only for the 1000W ballast instead of the 600 watt lamps. This is because the voltage for 600W and 1000W lamps are different. Usually the lamp voltage for 600W lamps is around 100V, and the lamp voltage for 1000W is around 200V. Are growlite ballasts more efficient than other leading brands? Yes, the efficiency of growlite ballasts is about 90-91% other brands usually have 89-90% efficiency. For example, the output power of 1000W from other leading brands is about 980W, while the ouput power for growlite is 996-1000W for the 1000W ballast. When dimming a growlite ballast why
