Panasonic's new EVERLED light bulbs to light up your life for 19 years
Long-lasting light bulb technology is nothing new -- people have been trying to up the lifespan these bad boys for some time. Long-lived light bulbs are generally uber-expensive, too, but we like to keep our eyes on such things. Panasonic's just unveiled the EVERLED, a line of bulbs set to be launched in Japan at the end of October. Lighter and more efficient than other LEDs on the market, these babies use 85 lumens per watt for a 40W bulb. Though the bulbs are not going to be cheap -- about $40 -- the company claims they'll have a lifespan of 19 years, bringing the overall costs down considerably. Still, we'd have to see them last that long to believe it. [Via Inhabitat]
Research team "near production" of a cheap lightbulb, lasts up to 60 years
We've seen plenty of high-efficiency lightbulbs rolling around, but this new one -- if it ever sees the light of day (groan) -- has impressive potential. Cambridge University's team of researchers are apparently quite close to bringing to production an LED bulb that can last up to 100,000 hours (about 60 years), and which -- unlike some other eco-friendly lighting -- contains no mercury. In the UK, where sale of some incandescents has been phased out, the team estimates they could reduce carbon emissions by about 40 million tons. The team has also significantly cheapened production by growing the LEDs on silicon wafers rather than the sapphire ones normally used, thereby bring the cost to... wait for it: $2.85. So when can we expect to see these badboys on the market? "Soon." [Via Switched]
