Vu1, a company based in Seattle, says it plans to introduce a new type of light bulb that can compete with CFL (compact fluorescent lights) and LEDs. Vu1 says the light will be a fully dimmable, mercury-free, instant-on bulb. It will, the company says, last about 6,000 hours – or six times the lifespan of an incandescent – and have a price tag similar to high-end C.F.L. reflector bulbs: about $18 to $22.
Vu1’s technology – which it has dubbed “electron stimulated luminescence” – shares some of the same basic science on which cathode ray tubes in older televisions are based. According to the company, E.S.L. creates light without requiring a filament, plasma, coils or mercury vapor. Electrons are sprayed uniformly over a broad area inside the bulb, which is coated with a phosphor mixture. This causes the entire surface of the bulb to glow and create light.

It is nice to see they are finally moving forward with this. I first read about this company, it seems, more than a year ago and despite claims of a new type of bulb I saw nothing since.
I wonder if these bulbs will buzz, emit radiation (like an old TV) and emit excess electrons through the surface.
Any competition to the current status is welcome. It will sponsor more innovation and price reduction through better design.
I wonder what part wears out after 6,000 hours? I’m not an expert but I don’t see how any of the electronics would wear out. So that leaves the phosphor mixture on the inside of the glass surface. If that is the case make the glass/phosphor front replaceable (unscrew the front and replace it) and you have a much better lifetime cost model.
