LED's give out heat when driven hard, if the lamp does not have enough sufficient cooling which in turn effects the lamps PAR output then its not designed correctly.

My second generation DIY light uses a lot more Aluminium bars for the heat sink and so it dissipates the heat extremely well with NO fans whatsoever. Its all passive heat dissipation and just warm to the touch, even at full blast (280w) after 8 hours. My tanks were much warmer in the summer with halides.
I wonder if Brad and the others who experienced heat issues with LEDs have them inside an enclosed canopy with not enough air movement?
