This intelligent light bulb uses a 2200mAh built-in lithium battery to store charge from an electric socket where it is installed. Once load-shedding strikes while the light is on, the light bulb automatically switches over to its own battery to continue providing light as normal. No need to do anything more.
With a 4-hour charging time, this energy-efficient light bulb can be controlled at the usual light switch even during load-shedding.
