I recently built a grow light, and I figured I'd share it. First of all, I want to thank SupraSPL and Greengenes. It is just a copy of a CXA3070 COB setup. COB stands for Chips On Board. I've been using it for less than a week. I'd say it covers around 32"x32" or so. Each cob covers about 15.8" at 30 watts per square foot.
Cree 208 Watt light
