It is amazing just how much research is being thrown at developing new light bulb technology. While much of the attention is being focused on CFLs, LEDs and even OLEDs, other technologies are in the works.
Here's one I hadn't been aware of until recently. VU1 Corporation has their first product out the door and it can be ordered directly for $19.95. (You need to order at least 8 of them) It is designed to replace a 65W incandescent R-30 flood bulb for recessed light fixtures but they claim to have other types in the works.
The bulbs uses Electron Stimulated Luminescence (ESL) which bears a certain relationship with CRT tubes.
"Electron Stimulated Luminescence Lighting Technology is an entirely new, energy efficient lighting technology. It uses accelerated electrons to stimulate phosphor to create light, making the surface of the bulb "glow". ESL technology creates the same light quality as an incandescent but is up to 70% more energy efficient, lasting up to 5 times longer than incandescent and contributing to the reduction of greenhouse gas emissions. There is no use of the neurotoxin Mercury (Hg) in the lighting process.
"ESL uniquely applies much of the science that has been proven over a long period of time in TV and CRT technology. However, ESL has made groundbreaking improvements in uniform electron distribution, energy efficiency, phosphor performance and manufacturing costs. More simply, CRT and TV technology is based on delivering an electron "beam" and then turning pixels on and off very quickly. ESL technology is based on uniformly delivering a "spray" of electrons that illuminate a large surface very energy efficiently over a long lifetime."
It will be interesting to see how this technology pans out in the long run, although they still haven't achieved the 100 Watt standard bulb equivalent.
