LED bulb with motion sensor and battery

Don't be left in the dark during power cuts with the BLACKOUT BACKUP emergency light. It works like a normal LED lamp and fits most light fixtures, but its internal rechargeable battery stays charged and ready to provide your home with up to 12 hours of emergency lighting. Simply screw it into a lamp holder, switch on the lamp or light fixture, and it will start charging its internal battery. The energy-efficient LED lamp uses only 8 watts, making it an ideal replacement for 60-watt incandescent bulbs and even compact fluorescent lamps. The included power adapter allows you to use it as a portable light, and an integrated hanging hook gives you the option to hang it anywhere, even if you don't have access to a lamp.
