When you produce/use a watt of electricity, heat is produced.

i would be bit careful, a damn good CFL gets about 100 lum/W but a HPS gets 150 lum/W (as long it is bigger then 399W
) and a 400W can be use at less the 4" if aircooled and only a ft if un-cooled. you can't beat that with a 100lum/W CFL 2" away from the plant - there aren't enough lumen lost on that way and HPS wins.
and that CFLs are totally cold is a myst as well, the get so hot you can burn yourself touching one. and so they can burn, and will so, leafs too.
