The strange affect of the guy on the left is offputting -- he acts like we're wasting his time. I noticed that he said that LEDs run for @ 3 hours per day may last 20-25 years, while the LED manufacturers claim this to be the bulb life for bulbs run @ 5 hours per day.
Kankin industries has invented LED without a heat -sink. Check them out.

Good info for housing construction.
The video was done well and the host presents well. The guy on the left looks completely bored and indifferent though.
