The brightness sensor reacts to lighting conditions, switching the night light on automatically when it's dark and off when it's light. The night light can be switched on and off or set to auto mode (for twilight sensor) by slightly turning the outer ring. It is simple, energy-efficient, and safe: connect the night light to the socket, with low energy consumption thanks to the LED that does not get hot. Electronic devices can continue to be connected thanks to the integrated socket, meaning no socket is lost. It also features increased touch protection to avoid accidental contact.
