A new kind of energy-efficient light bulb may provide an alternative to existing compact fluorescent (CFL) and Light Emitting Diode (LED) bulbs. The new bulbs, made by Seattle-based Vu1, use a technology called electron stimulated luminescence (ESL) to produce incandescent-quality light.
The ESL bulbs generate light by firing electrons to stimulate phosphor, and the whole setup is encased in normal light-bulb glass. The bulbs are estimated to last up to 6,000 hours, which is comparable to CFLs, and three to four times as long as incandescent bulbs.
Researchers develop a mercury-absorbing material that could take the risk out of recycling compact fluorescents

Compact fluorescent light bulbs solve one problem, but present another: Although the bulbs are longer-lasting and more energy efficient than incandescent bulbs, CFLs contain mercury, a neurotoxin. If a bulb breaks or isn’t recycled properly, the mercury can be released into the environment.
