Incandescents are out, LEDs are in! LEDs are more efficient, don’t heat up, are brighter, and last longer! (We have a couple of solar-powered outdoor walkway lights that are LEDs.) I just hope the white LEDs don’t look like garrish flourescent lights, but I don’t think they do. I hope. LOL. This is also a neat synch because I was thinking a lot about alternative energy and then this comes up – cool!
