The ESL: A light bulb that speaks the language of energy efficiency
Cheaper than LEDs and safer than CFLs, will ESL (electron-stimulated luminescence) light bulbs be a viable household replacement for incandescents?

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.

Rick: Before you go public commenting on a company or technology like Vu1 and their ESL, you should first try doing a little research. There are no similarities between LEDs and ESLs, except that they are both lighting technologies.
LED stands for light emitting diode, a type of solid state lighting technology. ESL stands for electron stimulated luminescence, a totally different creature. With ESL, you have a power module that sprays electrons onto a coat of phosphor, causing it to glow. This.... More
ESL is just another form of LED.
Lot of folks are using a similar technique to make LED equipment. All white LEDs use a phosphor to convert invisible energy to visible light. Fluorescents do the same thing. Vu1 has seperated parts that are usually in the LED package.
If Vu1 can make a better lamp for less, I say great. But their numbers don't add up, keep the facts straight. You can get a CFL lamp for far less than $20. Most LEDs are dimmable - and more are being released all.... More
The great thing about these light bulbs is shortly after your investment is returned due to the minimal amount of energy it uses. In places like commercial buildings it is very important because of the amount of energy consumed during the hours of operation.The lighting used for commercial buildings is an important aspect when moving towards an energy efficient building, due to monthly expenses.The T5 Retrofit Kit is a great product to use for energy efficient lighting, which can save up to....

Vu 1's ESL bulb cost is about half the cost of the non-lead alternatives. The color is better than the alternatives when viewed in person. The authors are acurate in their description.

I like the idea that these cost less to make than LEDs or CFLs, but will cost $20 each. So the extra money goes to... ???
Since I have dimmable CFLs and bulbs with better colors than they show, I find the whole thing a little suspicious. I urge the authors (and teh site) to be a little more skeptical of the claims from the salepeople.
