LEDs are lighting our way to the future

Incandescents are so last century, a thing of the past and a relic of Thomas Edison — at least in the European Union, Switzerland and Australia. Other nations are also instituting gradual phase-outs and bans, including Canada and South Korea this year. Incandescent light bulbs consume, on average, about six times the energy of an LED light bulb. For a standard 60-watt light bulb that might be in your bathroom, an LED bulb would use only 10 watts. Halogen lights, a popular alternative in the United States, would consume about 43 watts.
