Don't waste your money ,
It only makes 8000 lumens and they are comparing it to a 600w. hps . hid. that makes about 90,000 lumens . You can make your own cfl fixture that makes about 10,000 lumens for $20.00 , or spend your 149.00 on a 250 hps and a small duct fan to cool it w/. Do somemore research before spending any money .
