Here is a rechargeable light bulb that works even when you are experiencing a power outage. It can also be used as a handheld flashlight. The light bulb fits into any E27 or E26 screw-in light fitting and can replace a 40 watt incandescent bulb. There is a 3-position sliding switch on the side of the light to let you control your light. The small LED on the side glows green when the batteries are fully charged.
When you are ready to use this like a flash light, simply pull and extend the handle. The flash light can remain lit for up to 3 hours. Sets you back £24.99.
