New Lighting Technology Offers Alternative To CFLs and LEDs
Residential Lighting reports that a new energy-efficient lighting technology, dubbed ESL (electron-stimulated luminescence) was patented in June by a startup company called Vu1.
The technology works by using accelerated electrons to stimulate a phosphor coating on the inside of the glass bulb. In contrast, incandescent bulbs run a current through a filament inside the bulbs, and LEDs stimulate semiconductors to create light.
The first ESL prototype is expected to output 40 lumens per watt with a 6,000 hour lifetime.
So why is the ESL bulb any better than CFLs or LEDs?
