Energy Saver
LED is a highly energy efficient lighting technology. Residential LEDs use at least 75% less energy, and last 25 times longer, than incandescent lighting.
"By replacing your home's five most frequently used light fixtures or bulbs with models that have earned the ENERGY STAR, you can save $75 each year."

*Based on 2 hrs/day of usage, an electricity rate of 11 cents per kilowatt-hour, shown in U.S. dollars.
Widespread use of LED lighting has the greatest potential impact on energy savings in the United States. By 2027, widespread use of LEDs could save about 348 TWh (compared to no LED use) of electricity: This is the equivalent annual electrical output of 44 large electric power plants (1000 megawatts each), and a total savings of more than $30 billion at today's electricity prices.
