New Panasonic LED LightbulbS Rated at 19 Years

Panasonic is set to release the EverLed series of light bulbs-the most efficient LEDs ever produced- next month in Japan. The bulbs use 1/8 the power of an incandescent and are said to get up to 19 years of burn time. They will retail for roughly $40 US and use only 85 lumens per watt for 40W bulbs and 82.6 lm/W for the 60W bulbs so the cost to run one could be as low as $2 per year when their 19-year lifespan is taken into account.
