Reply #22: I've been using color LEDs in my art

They're digitally controlled with up to 16,000,000 colors. White LEDs aren't quite comercially viable but look for them in the next couple of years. With a life of somewhere between 50,000 and 100,000 hours and much lower energy usage look for them to become the standard. Personally I think a smaller company, perhaps Color Kinetics will lead the way. GE, Sylvania and Phillips are invested in current incandescent and flourescent products and may not have the motivation to push LEDs. You can get a edison style LED bulb for about $50 now, but the price will drop and low voltage LEDs will start appearing in homes and commercial buildings in the next decade.
