Then I have concerns about that LED. why would my tank running on LED be any different to the next, I dont need a chiller and never have running LED.

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?

Yes, I had mine in a canopy.

Okay so what's the consensus? Should I switch to LEDS? Maybe I should ask in a poll.

Okay, but it needs to be he best poll ever or it's not even worth voting.

Absolutely.

well that will explain the heat issue, unless specified otherwise LEDS are not designed for canopies.

I've always had my Radions enclosed, incl my Gen 1s, and never had any issues. They are well vented, of course, and a lot cooler than the T5s that used to be in there.
