The brightness sensor responds to light conditions and automatically turns the night light on when it is dark and off when it is bright. The night light can be turned on and off or set to automatic mode (for the twilight sensor) by gently rotating the outer ring. It is simple, energy-efficient, and safe: plug the night light into the socket, with low energy consumption thanks to the LED that does not get hot. Electronic devices can still be connected thanks to the integrated socket, ensuring that no outlet is lost. It also offers enhanced touch protection to avoid accidental contact.
