So I read this article in the paper about how led lights are becoming more popular for household lighting. They produce less heat and use more of the consumed energy to produce lighting. They are, however, expensive. The article said they are coming down in price by about 20% a year. I was in Home Depot today and didn't see any LEDs in the light bulb section. I didn't ask an HD employee if they had them, so I don't know for sure that they don't. Where would I find these babies for sale? Anyone using them for their household lighting? Are they constructed so you can replace a regular lightbulb with them?
