Panasonic has launched a new household LED lightbulb in Japan that apparently lasts 40 times longer than incandescent bulbs.

The new LED bulbs are in the EverLed line, and they’ll be siold in Japan starting October 21, with monthly production at 50,000 units. No changes to lighting equipment used for incandescents are required.

If used an average of five and a half hours per day, the new bulbs can last up to 19 years, according to Panasonic. That’s 40 times longer than incandescent bulbs. The bulbs use 1/8 the power of regular bulbs.
