Ever since Edison invented his famous light bulb that’s probably providing light to you right now, people have not been pleased and keep searching for alternative lighting solutions.
Residential Lighting has invented a new type of light bulb, that claims green gains, even more green than the CFLs. The new technology is called ESL (electro-stimulated luminescence). The technology was patented in June by a startup company called “Vu1”.
These new light bulbs have a phosphor coating that is stimulated by accelerated electrons inside them. In contrast, incandescent bulbs run a current through a filament inside the bulbs, and LEDs stimulate semiconductors to create light.
The ESL technology does not involve the mercury than CFL technology does, and it is cheaper than LEDs, because the light bulbs’ manufacturing does not use that much energy.
ESL bulbs are estimated to have a price of $12, about the same price the CFL, offer 6,000 working hours with an output of 40 lumens/watt, and will be available for the market starting this September.
