Change out incandescent bulbs for energy-saving compact fluorescents or LEDs

LED bulbSave energy starting today with energy efficient LED or compact fluorescent light bulbs

LED light bulbs are the best choice in lighting for price and quality. Bulb costs have fallen and variety has increased. LED bulbs come on instantly, function well in cold temperatures, and contain no mercury.

Compared to "efficient" incandescent bulbs on the market today, LEDs use 85 percent less energy and can last up to 25 times longer.

Use LED bulbs to replace incandescent bulbs of the same watts, in the fixtures you use the most.


Look for the ENERGY STAR label when you buy CFL or LED bulbs. ENERGY STAR bulbs have been tested for color quality, light output, energy efficiency, and must carry a minimum warranty of 3 years.
