We chose the nightlight described here because these fastening was exactly possible and the previous reviews were very positive. Unfortunately I can not confirm that.
The copy delivered is simply blind. At first I thought that the sensor may be disturbed by the stair gate. So I put the night light on a tripod and am frontal running up it. Respectively at 50 cm above the ground and 120 cm above ground. The position of the screwing I changed (1st drilling vertically, 2nd hole 45 ° to sSenkrechten rotated). Sometimes the light switches at about 3 m distance, but in most cases I had to approach to less than 1 m, so that the sensor recognized me. According to product specification (packaging) the device should still work cleanly on 5 m.
Conclusion: Einspricht not the specification and is therefore unsuitable for my purpose.
