redtails Reviewed by redtails on . automotive HID lights vs. cfl's Hi, I'm starting this thread to compare a variety of lights for small closet grows. First i'm posting only light outputs of 250 watt 6400K vs. 250 watt 25000K vs. automotive HID lamps. I built three indenticle boxes 24' X 22" x 36". I'm measuring output at the bottom of the box. in the first photo the box on the bottom left is the 6400K 250 watt cfl, bottom right is the car HID and the top is the 250 watt 25000K. Average light output are as follows. 250/6400K 5000lux peak was 5410 lux, Rating: 5
