New Highly Energy Efficient Light Bulb Can Burn for 100,000 Hours and Will Only Cost a Few Bucks
Researchers from Cambridge University in England have developed a relatively inexpensive way to manufacture a light bulb that is three times more energy efficient than a compact fluorescent bulb and should last an amazing 60 years according to an article in the Telegraph. Gallium nitride, which is used for special types of lights such as camera flashes, is also used in making these new bulbs. The breakthrough came in the manufacturing process which will permit a bulb to be sold for only a few dollars instead of almost fifty dollars. Another plus for the new bulbs is that they can be dimmed whereas an ordinary compact fluorescent can not. If these bulbs, which supposedly will be available for purchase in two years, are as good as advertised, this raises the issue of whether to continue replacing ordinary incandescent light bulbs with compact fluorescents or wait for the new bulbs to arrive in the stores. That should give Al Gore something to ponder.
