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.
