Finally, LED lights are becoming affordable - and more and more common. We bought our first LED bulbs a couple months ago at Home Depot. Out of curiosity, I had stopped in to see if they were carrying them yet. I didn't see any and asked the first HD employee I saw.
"Sold out," he said, "should get more in Friday."
I looked at the one empty slot on the shelves - amidst hundreds of options for different bulbs of all types, shapes and sizes. "That's a good sign," I thought to myself.
I went back the next weekend and picked up a few bulbs that fit these weird candelabra fixtures we have in our new rental. They're not super cheap - about $14 for a pack of two. But they use about 90% less energy than the old incandescent bulbs, so they'll pay for themselves over time. And when I see the coal plant burning less than a mile from our house, and know that we just took demand down a notch, that's priceless.
