ESL — the newest, greenest light bulb around

Recommended Posts


Just as the world is getting used the cool-glowing, coil-shaped Compact Fluorescent Light bulbs (CFLs), Seattle-based Vu1 has come up with a whole new bulb technology that's even better… and greener. Instead of heating a filament like in an incandescent bulb, or sending a current through mercury vapor as in a fluorescent, Electron Stimulated Luminescence (ESL) bulbs use accelerated electrons to stimulate the phosphor coating on the inside of the bulb, making the surface glow.

The result? Bulbs that give the same quality as incandescent lighting but use less energy. And unlike CFLs, no mercury is used (and later, thrown out). There's no pricing yet, but Vu1 says they’ll be similar to CFLs — pricier than incandescents but not LED-pricier — when they debut in mid-2009.

Right now, Vu1 plans to focus on reflector bulbs, the recessed flood- and spotlights you might see in a small retail store, but the ESL technology allows the bulbs to be more flexible in shape. So you can have a classic bulb shape instead of a weird corkscrew-shaped CFL in your reading lamp, and still pat yourself on the head for being green. They can even mimic the shape of big commercial fluorescent tubes, currently being used to sap your will to live at work.

Click the link for the picture of the bulb. From what I was reading, it sounds like these bulbs will be about the same price as the CFL bulbs. And these don't have mercury vapor in them and they are dimmable. I'm definitely going to buy one of these for my flood light outside. It'll probably last years upon years before I'd have to replace it again. ^_^

      Wow. 19 freaking years. I want a floodlight one. I'll never have to change that damn bulb again.

      I would copy and paste the article, but it has a bunch of pictures and what not. Its a pretty good read.

      Wow. Recycle the CO2 back into fuel. Now that would be some green tech. But what was the one part about a poison side effect? Was he talking about poison messing up the process or poison as a side effect? I think he means the former, because if recycling CO2 would mean pumping poison into the atmosphere instead, this would be the worst project ever. X'D
      But damn, recycling CO2 would actually be pretty huge.
