Very very bright, wide detection range, unfortunately, turns out again and again

Positives:
The lights are bright. Really very bright. 1 which illuminates a space of about 4 sqm slack off.

The motion sensor is also very good and very broad. I maintain, he recorded everything at an angle of 170 ° up to 2m distance, that's really impressive.

Negatives:
The lamps light 20sec long and then go out again, even if you move it. After about 4 seconds then go again. For longer illumination of a room so they are only partly suitable.
