What are LEDs?


Light emitting diodes (LEDs) are a type of solid-state lighting; semiconductors that convert electricity into light. If you haven’t been down the lighting aisle of your favorite home improvement store lately, you may be surprised at how many LED lighting products have arrived. Although once used primarily for indicator and traffic lights, LEDs in homes and businesses are one of today’s most energy-efficient and rapidly-developing technologies. LEDs are six to seven times more energy efficient than conventional incandescent lights, cut energy use by more than 80 percent and can last more than 25 times longer. 

LED bulbs are currently available as replacements for 40, 60, 75 and 100 watt incandescents, reflector bulbs (used in recessed fixtures), small track lights, three-way bulbs and even holiday light strings. 


How much can I save?


While LEDs are more expensive at this early stage, they still save money because they last a long time and have very low energy use. The Department of Energy estimates using a traditional incandescent bulb adds about $4.80 per year to the average home electric bill. A compact fluorescent light (CFL) adds just $1.20 per year and an LED about $1 per year. That means a typical household could potentially save about $50 per year by replacing 15 incandescent bulbs.

Buyer beware


Poor quality LED products are flooding the marketplace. Some are manufactured outside of the United States with components that produce low light levels, don’t have a long service life or make exaggerated energy saving claims.  

Don’t be fooled. Look for the ENERGY STAR® logo for guaranteed color quality over time, steady light output over the lifetime, high efficiency and a warranty.
