Yeah i know they do put out some heat...but 2 4' 8bulbs WOW! I wouldnt imagine something like that being 'cool' necessarily.

I have light experience with CFLs but I figure Ill do like postman, 1" or so with the single 4bulb fixture with a fan cooling between the 2...and of course adjust height as needed for heat.
rygo796 Reviewed by rygo796 on . T5 Fluorescents Anybody ever try growing under T5 fluorescent lighting? I Figure I could fit a 4 bar 4foot setup in my clsoet which would work well for heat issues, and they say they put out 5000 lumens per bulb, which I could scrog under and being so close to the plant it would be like using somewhere between 250 and 400watt HPS. Any thoughts? Rating: 5
