Rebates to cut price of $60 LED bulb – Yahoo! Finance. A brand new light bulb that won a $10 million government contest goes on sale starting Sunday…Earth Day. It is the most energy-efficient, and lasts about 20 years. It took a year and a half from creation to the testing. It uses only 10 watts of power saving about $8 a year in electricity if you use it 4 hours a day. CFL are almost as energy-efficient and much cheaper costing about $5. The New bulb costs about $60, but with rebates it is supposed to cost about $22.
“The race is now on to produce LED bulbs that produce 100 watts worth of light. The incandescent equivalents are no longer made or imported, victims of a federal ban that kicked in at the beginning of the year. They’re now starting to disappear from store shelves. Squeezing enough LEDs into a bulb-sized space to produce that much light is a big technical challenge — LEDs generate heat, which destroys them over time unless they’re well-cooled.
Incandescent bulbs of 40 watts and above will be banned in 2014. ”
It seems as if we will be spending a bit more for our bulbs of the future unless we want to revert to candles. You always have to pay for technological advances. But since the new LED bulb will last for 20 years, you can’t argue with the price.
