Anyone notice that Luxim is creating some very interesting light bulbs, not available to general public yet. http://www.luxim.com/
Basically just microwaves the argon and sodium inside a closed bulb about the size of a tic tac, and a rather amazing amount of light is produced. It is supposed to double the efficiency of LED technology in some cases. And the CRI rating is around 90, so very high quality of light, and not much energy. I think they are daylight balanced by default, but surely we could just burn a different type of gas and produce 3200 some day soon?
