They have been using them for car tail lights for a few years now. That
works fairly well, though replacement is expensive. And yes, they do burn
out because they have to drive them quite hard to get enough light out of
them. Problem with running them at 120v is that an LED only requires a
couple of volts to run. There are different schemes to drop the voltage, but
in the end they are not very efficient. Not yet.

I have some LED Christmas tree lights that work very well, and consume
significantly less power. By running a while bunch in series, you get away
from the need to have to drop 100V or more across some load or transformer
or whatever. No ballast, no hot bulbs, no crap made-in-China bulbs that burn
out all the time (instead you have crap made in China LEDs that last at
least a few years LOL). LED Christmas tree lights are the way to go.

They can barely get CFLs to work reliably, and the cheap ones are crap. It's
gonna be years before LED lighting hits mainstream.

Is it there yet or still hype?
