I have them for the new bulb with 7 LEDs. I have the bulb 20" above my 8" frag tank and I'm getting a reading of 350 in the center of the tank.

I have two on my 18x18x8 frag tank. No heat issues at all. Here's some pics of what I have in the tank.

I'll take some pics and post them a little later. I have to 60 degree lens on mine. You might want to email michael at rapidled and see what he suggests based on how high you're hanging them.
