Hmmm . . . Now which will be better, cool tungsten light bulbs, or cool LED light bulbs? Of the LED light bulbs, I've read that the bulbs will never burn out and you could, for instance, operate a bright flashlight continuously for a month before the batteries would need to be replaced. Now that's efficient! I've already seen these LED flashlights in some of the junk mail catalogs I get. The future is gonna be interesting.

"So it hasn't ACTUALLY worked yet. But we're sure it will."

Wait and see.
