Where will you be when the lights go out?

This Smart Light Bulb Keeps Working Even If the Power Goes Out

The SmartCharge looks like an ordinary LED light bulb, except that it’s got a built-in rechargeable battery. When the power to your house is working as it should, the SmartCharge acts as just another lightbulb while topping off its internal battery using your home’s wiring.

When the power goes out, however, the bulb will keep working for up to four hours. And what’s more, it’ll remember the last position of the light switch that’s controlling it.
