I hate to disappoint you, but LED's are not much more efficient than
incandescent lightbulbs. Both get are up to 20Lumens/Watt. Why do you
think a 5W Lumiled needs a heatsink ? Most of it is pure marketing hype
of vendors selling expensive LED lights.

Efficient lighting today means fluorescents. They are 3-4 times as
efficient than incandescent/LED's. The only area where LED's are more
efficient is in the very low power area (status indicators, small
flashlights, etc.).

See http://www.otherpower.com/otherpower_lighting.html for an easy to
read article about the subject.
