CFL Light Bulbs

LEDs run cooler than incandescent bulbs, but when you are trying to produce several hundred or 1000+ lumens, you have to drive the diodes with a pretty decent current. They will get warm to hotish, and this decreases the lifespan of the diode.

Look at some of the current LED bulbs on the market, and you will usually see some metal cooling fins or heat dissipation devices.

There is a tech startup called 'Switch' working on bringing a better LED bulb to market. Google 'switch led bulb cooling' or something like that and you should find some articles.
