The LED bulbs I've linked to above are probably about the same brightness as a 25 watt incandescent bulb. My thought is to replace some of the CF lighting I current have in hallways with these LEDs. These tend to remain on for quite a long period (despite my efforts in constantly turning them off...). The electricity savings wouldn't be that much, but why use more electricity than you absolutely need.
I read somewhere that if the whole country replaced one incandescent light bulb with an LED, we could eliminate the need for one nuclear facility. Not bad! And since my state uses coal for about 78% of its electricity, reducing watts is something I am very willing to consider.
Another concern is that CF bulbs certainly don't last as long as advertised and I'm totally not sure of how to dispose of them. LEDs should last much longer, probably some of them until I sell this house!
