With illuminated bulbs set to be gone from the US in a subsequent couple of years, a foe for replacement tech is heating up, if you’ll forgive a joke. The ultimate new lightbulb from theSeattle-based Vu1 is the ESL, or Electron Stimulated Luminescence, which “uses took off electrons to kindle phosphor to create light, creation the aspect of a tuber ‘glow’.”

Efficiency is approach up from incandescents: Vu1 claims the 70% increase, along with 5 times a life of the normal tuber. The first units out of the bureau will be swap in replacements for a 65-Watt units usual in households, and will price around a same as compact fluorescents, about $20.

But all this is for nothing if you buy the bulb whose light is so nauseous you daren’t switch it upon. I have a giant creation unresolved in a core of my room that hives out a lovely even light from a LEDs inside, and runs cold as well as fit. The complaint is I didn’t pay courtesy to the color temperature tag, and a light it produces is so cold and routine it could have George Hamilton look similar to the dark cadaver.

Don’t be concerned, yet, as a ESL is colored just a touch cooler than an illuminated tuber, and reduction immature than the CFL. It is also fully dim-able, meaning you can eventually barter out a lights in your chick-magnet bachelor desk pad.
