The Casto Sensor LED light fixture can be used in a variety of ways and ensures orientation and safety in children's rooms, hallways and cellars, for example. The LED light is simply plugged into the wall socket and is therefore ready for use at all times. Particular highlight: The Casto Sensor has both a motion sensor and a twilight sensor. These are permanently activated. They switch on the light when they detect movement after dusk. The Casto Sensor can also be used as a practical torch and has an emergency light function. If the power is lost, the torch turns on automatically thanks to the battery.
