LED Patents - Action Needed!

Ya, IIRC, PFO had more power supply issues then burnt out LEDS. But, these high power LEDS NEED cooling. Just cause they don;t heat your tank up, doesn't mean they don;t make alot of heat.

they make a fraction of the heat a MH or T5 do because of the efficiency of the LED chip its self, so a very small amount of the power supplied is turned into heat. the cooling they need is for the actual die of the LED chip, if it gets to hot it decreases the life of the chip. if you keep it cool the chip is happy. so they are mounted to a heat sink, with a couple fans blowing air into the fins of the heatsink. so yes there is a small amount of heat produced, but it is put into the room the tank is in instead of the tank.

Guess I should have specified, Alot of heat for their size. yes, it's not as much as MH or T5, but heat still kills LED's

The reviews on the TMC fixtures aren't great. They may also be paying Orbitec a royalty on US sales.

I also came accross this which shows some side by side pics of 2 months of coral growth under LEDs (post #9). Looks alright to me
