LEDs are pretty slick in how effective they are, are pretty much the way flashlights are going now. Nothing else provides as much light and endurance
with a given battery. Soon enough for automotive applications, and it'll be unlikely you'll ever have to change a lightbulb on a car. Still kind of
pricey for household lighting too, but like others have said, wait for mass production to kick in and defray the costs.
Of course they still aren't suited for high temperature applications such as ovens (LEDs tend to die rather quickly when they get too hot), but there
is a fairly obvious work-around for that - keep them away from the heat by channeling the light with fiber-optics.
However there's been a patent on that already... www.google.com...
We'll probably see LEDs used in ovens (both conventional and microwave) as soon as that patent expires. (I'm guessing the license holder is being a
bit stingy and only releasing to high-end manufacturers, or we should be seeing that method of redirecting light used all over the place by now.)
