It looks like LED efficiency just went through the roof. A North Carolina newspaper recently reported.
He said a just-released federal study confirms that the product is the most efficient in the world. It uses 5.8 watts of power, compared with 60 watts for an equally bright incandescent bulb. According to the report from the National Institute of Standards and Technology, the new fixture uses less than 9 percent of the energy consumed by common bulbs and less than 30 percent of that consumed by fluorescent lights. LLF's best existing product consumes 15 percent of the energy used by an incandescent bulb and 50 percent of that used by fluorescents.So why is this a big deal? Count the greenbacks:
"The Department of Energy has estimated that LEDs could reduce national energy consumption for lighting by 29% by 2025. That would save U.S. households $125 billion on their electric bills."Sources:
