If the next light bulb you buy is an LED, it may be your last.
The technology behind light-emitting diodes has advanced to the point that the bulbs can replace traditional 40- and 60-watt light bulbs and last up to 25 times longer.
"You're going to see people say, 'I'm taking my light bulbs with me to my new home,'" says Bill Nottingham of Nottingham Spirk, a Cleveland-based industrial design company that's working on LED lighting technology.
Traditional light bulbs are on the way out. The U.S. mandated a phaseout of the most common wattages of incandescent bulbs; inefficient 100-, 75-, 60- and 40-watt bulbs will not be sold after 2014.
