Even among consumers, LEDs are gaining both recognition and popularity, but in many cases they're known only for one thing: energy efficiency. This certainly isn't a bad 'reputation,’ and LEDs offer excellent benefits to support this: • They last up to 40 times longer than incandescent lights, reducing replacement time and costs. • LEDs use up to 50 percent less energy than CFLs; 75 percent less than halogens and 85 percent less than incandescent lights. • They typically realize a return on investment within two years or less. • They often have a lifetime that can exceed 50,000+ hours. And, according to the U.S. Department of Energy, a 12-watt LED provides the same amount of light (about 800 lumens) as a conventional 60-watt incandescent.
