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.
