yep agree with thefirstissoon. no closer than 18...(i'm assuming HPS, MH dont get quite as hot) but I'd keep either one around that distance

I agree. Mine are air cooled & fanned across canopy. I keep them 3ft away and run 12 in one room.

This has been floating around RIU for awhile, it may help some folk to maximize PAR.

Say again? Metal Halide does burn brighter and hotter. It's not th other way around.
