Say hello to the newer and greener 'ESL' bulb
Just when everybody is finally starting to get all their light bulbs switched over from incandescent to CFL there's a newer, greener kid on the block: the ESL. Created by Vu1, ESL (Electron Stimulated Luminescence) bulbs create light by accelerating electrons that then stimulate a phosphor coating on the inside of the bulb, which makes the surface of the bulb glow. CFLs, on the other hand, send a current through mercury vapor to create light. ESLs both use less energy and are free of the toxic element Mercury, plus they can be more than just one shape (no more funny looking corkscrews!).
Look for ESL bulbs to be priced similarly to CFLs and to be available starting sometime next year.
