Under normal circumstances, it can be used just like regular lighting, but if there is a sudden power outage it will automatically detect and immediately start providing emergency lighting.

The built-in storage battery uses a high-performance, highly safe lithium iron phosphate battery, which provides emergency lighting for up to 10 hours with a brightness of approximately 300lm (equivalent to a 25W small light bulb) in the event of a power outage, supporting peace of mind and safety during long-term stays.
In addition, in situations where light is not required, such as during the daytime during a power outage, the light can be turned on and off by operating a switch on the power outage detection transmitter.

Excess electricity can be stored to prepare for power outages at night.
