For most heat I would rank them like this:

1 - HPS
2 - Metal Halide
3 - CFL
4 - LED

Hope this helps! :rastasmoke:

Thanks for the invite. Just curious, is this part from personal experience, or is it just an assumption?

HPS puts out LESS heat than MH because it is the most efficient. More watts turned into light less turned into heat. MH runs HOTTER because it puts less energy into light, and more into heat, of course because it is less efficient. I would have thought someone with your VERY EDUCATED OPINION would know that, but hey, it's just an opinion right?
