LED Lighting for the home

I have recently been taking an interest in LED lighting. I am going to order some GU10 LED spotlights and evaluate them over the coming week. This is the kind of performance that can be expected:

In 2008, SSL technology advanced to the point that Sntry Equipment Corporation in Oconomowoc, Wis. was able to light its new factory almost entirely with LEDs, both interior and exterior. Although the initial cost was three times more than a traditional mixture of incandescent and fluorescent bulbs, the extra cost will be repaid within two years from electricity savings, and the bulbs should not need replacement for 20 years.[1]

If it goes well I will look into getting LED lighting for the whole house!
