Imagine if you had a light bulb that stays on even when the power goes out? Such a light bulb now exists, and stays lit, at least for 4 hours.

“This has never been done before,” said Shailendra Suman whose LED light bulb, SmartCharge, wowed audiences and the media at the International Consumer Electronics Show in Las Vegas last year.

The SmartCharge works just like any other light bulb, except that when the power goes out, the light bulb will keep working for up to 4 hours and will remember the last position of the light switch controlling it.

If you were not at home when the lights went out, you should still have 4 hours of light if nobody turned on the light switch.

The light bulb is also estimated to last 25 years.
