Our 15W 200 Lumen LED light bulb is equipped with an 2200m rechargeable battery that allows the device to switch on automatically when there is a power outage.

A built-in sensor can determine whether the power failure, and then determine which state the switch,and then decide whether to illuminate the room was waiting for someone else to open the switch.
Only bright light was able to continue because it is a built-in 2200mAh lithium battery that provides up to 4 hours of use. If power is restored, the built-in battery will take about six hours to full charge,ready for the next power outage.
Smart Charge lamp life up to 40,000 hours
