As with other technologies, advances in lighting just keep coming. Now that you’re somewhat comfortable with CFL — compact fluorescent lamp — bulbs, get ready for things to change again. The latest generation of LEDs — light-emitting diodes — are here and manufacturers claim they rival the look, dimming ability, and light quality of incandescents. Better yet, LEDs contain no mercury, and last up to five times longer than CFLs and 50 times longer than incandescents. They are pricey, many sell for $60 or more, but could save about $300 in electrical cost over its life compared with an incandescent.
