A novel design for energy-efficient lightbulbs can produce incandescent-quality light and does not contain mercury like compact fluorescents (CFLs), according to manufacturer Vu1.
The Seattle-based firm has been working on an alternative to CFLs and LED lights for five years and just rolled out a demo video, below.
Vu1's Electron Stimulated Luminescence (ESL) lights can last up to 6,000 hours, about three to four times the lifespan of incandescents and comparable to CFLs. They produce 50 percent less heat than incandescents.
The ESL bulbs contain an electron source that fires electrons at a proprietary luminescent phosphor, which then … Read more
