Description
Rechargeable bulb can continue lighting home and office after power outage. It automatically switches to AC power when there is electricity and also begins charging while lighting the room.
When electricity is out, it automatically switches to DC inbuilt battery and continues lighting the room for several hours.
It can determine if you are using the switch to turn off the light, or the emergency of a power outage. If power outage, it will continue to provide hours of illumination. If turned off by switch, it remains off just like normal electricity bulbs.
