ESL (Electron Stimulated Luminescence): Move Over CFLs and LEDs, There's a New Eco-friendly Lightbulb in Town

vic_butterfly.jpg Changing your light bulbs from incandescents to compact fluorescents (CFLs) has become the mantra of the green movement for what one individual can do to lessen their contribution to global warming; however, CFLs contain trace amounts of mercury making them hard to dispose. Vu1 has created a "light without compromise" with the ESL (Electron Stimulated Luminescence) bulb. According to CleanTechnica:
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...Vu1 claims that their bulbs do not have the trace amounts of mercury that CFLs contain, and they do not require the manufacturing energy of LEDs.
ESL bulbs should be available next month and retail for about $12.
