Mike writes "As lighting manufacturers phase out the incandescent bulb, and CFLs look set to define the future of lighting, Panasonic recently unveiled a remarkable 60-watt household LED bulb that they claim can last up to 19 years (if used 5-1/2 hours a day). With a lifespan 40 times longer than their incandescent counterparts, Panasonic's new EverLed bulbs are the most efficient LEDs ever to be produced. They are set to debut in Japan on October 21st. Let's hope that as the technology is refined their significant cost barrier will drop — $40 still seems pretty pricey for a light bulb, even one that promises to save $23 a year in energy costs."
