Practical Robin outdoor wall light with sensor, black frame and LEDs This outdoor wall light with a sensor combines the modern and the classic. Modern characteristics include the energy-saving LED bulbs, which sit behind the discreet, white cover. The sensor also represents a special feature: Outdoor wall lights with sensors react far quicker to events in the environment than someone having to turn on the light on ever could. As soon as someone enters the sensor's range, it sends a signal to the LEDs so that they illuminate. Once the movement has stopped, the light automatically switches off after a short period. Energy efficiency class:A+
