I have attached 2 of these lights on my Hoftoren in 3 -3,5m height. Optically very chic to look. Unfortunately, the motion detector has a large blind spots, that is when you walk out of the gate under the lamp must be only a few feet from the front wall to be removed before the motion sensor is active. Very annoying when you want to shut the door in the dark but the keyhole does not see. The BM seems to be rather insensitive, unfortunately this is no adjustment of sensitivity possible. Another disadvantage is that the burn time is not adjustable. I think with an additional motion detectors are to solve these problems, but then you might as well buy a lamp without BM.
