Move over CFLs and LEDs

The ESL (electron-stimulated luminescence) light bulb is coming.

So why is the ESL bulb any better than CFLs or LEDs?

Vu1 claims that their bulbs do not have the trace amounts of mercury that CFLs contain, and they do not require the manufacturing energy of LEDs. The ESL bulbs, which will cost $12, are about the same as dimmable CFLs. We can expect to see these on the market fairly soon—Vu1 says the first screw-in models could be available as early as September 2008.
