Check out this 3M LED Advanced Lightbulb. Highly efficient, soft lighting that *supposedly* lasts for a quarter century. It's the newest technology in home lighting, these bulbs run on light emitting diodes (don't worry about the facts - they're just good). If you want the newest and the latest in your home, this should be high on your list. These bulbs screw into a typical socket, making them that easy to install. The only decision you have to make it which model you want to get: the 3000k soft white light, or the 5000k cool white light. At $25 per, it's a little costly to outfit your entire home with them, but if you do that as your old bulbs wear out, it shouldn't be too hard on the wallet.
