OK, I just took delivery of an LED GU10:
Deltech GU10 LED 5W High Power Warm White LED Light Bulb
I put it in a fitting at work to try it out. First impressions are that this is a nice light - certainly better than the CFL version I have at home. Now, do I go ahead and buy a bulk pack?

Kim and Schubert claim that the LED is to lighting technology, what the transistor was to the vacuum tube.
One commenter disagreed with this and I tend to agree with that person. They said that since LEDs are more efficient they would produce less heat. The reason I agree with this is because of incandescent lights being less efficient and the side effect of that is that they produce a lot of heat therefore getting pretty hot. So, I was just wondering if what that poster said was true. I am referencing comments 5-7 of the Auto Blog Green article posted by malcolm.And while it may not make sense to you regarding the heat issue, it is the case...LED Achilles heel is heat buildup. Heat buildup is relative to size not absolute amount.
Yes, it may be a bit counter intuitive, but heat dissipation for high power LEDs is a major issue.

... The inherently high power density of the LED poses a significant thermal challenge for conventional cooling schemes. With the advent of reliable liquid-cooling systems in recent years for applications such as high-end workstations, there is now a viable approach to solving the thermal challenges of cooling high-brightness LEDs in the high-end display industry...
Ever wonder how efficient a candle is at producing light? The answer can be found here. In this image Nextreme Thermal Solutions is using a new thermoelectric material that can convert some of the heat from a candle into electricity. That electricity is then run through an LED. The LED and the candle combined put off more light than two candles would.
