This, by the way, is the key to using High-output LEDs - heat. They do not generate *much* heat at least as compared to filaments or even CFL lamps - but they generate a great deal of heat per square mm from the actual emitters. Most designs I have seen (Cree, RAB and more) use a heat-sink glue (Thermal Adhesive) on pretty substantial finned heat-sinks. Even my LED Mag-Lite uses a fat heat-sink design on the threaded lamp holder.
