Well I jumped on the LED wagon with both feet and spent $750 on a new light. Though I love my 630w luxx cmh I don't like it's cost to run. So the light I purchased is the phantom photbio mx 680w LED. The light normally goes for 850-1000 so I feel I got a deal at 750 just hope it performs as well or better than my cmh. What do you guys think? Anyone running these?
