The Nightlux lamps switch sch a quickly once man comes into the range of the motion. The range is very wide, when the light is mounted on the ceiling, about 3m in any direction. The light output is sufficient for orientation, corresponds ungeführ an LED flashlight with a wide spread. The lighting duration can be adjusted in two stages, 10s and 60s. Unfortunately, you can not set the date from which Nightlux it dark enough stops to intervene. This means that it is already switched on during the day in indirectly lit hallway, which of course is absolutely unnecessary. I would have preferred if you had a controller with which one could adjust the lamp feels addressed only with almost absolute darkness.
However Genial is the attachment. The tape of the magnet keeps excellent on smooth surfaces such as door frames, wooden ceilings, etc. For rougher surfaces, I would recommend Tesa Power Strip. Screwing or -dübeln is completely unnecessary.
