I have two motion detectors in the hallway in use. The detection range is very large, unfortunately, goes through a glass door through. A detector, I had to replace a few months, since the electronics is no longer starred. However, I had operated with a total of 4 W two LED lamps. That was probably too little. The installation is intended directly via a junction box, with a second box for the lamp. Since I did not have this, I had the plaster under the detector wegmeißeln so that the wires and the terminals had space. The detector has connecting cables from stranded wire.
