ESL Light Bulb Vu1 Corporation 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.
