I bought the lamp as a replacement for an old L 100 S. Previously I had just informed me on the manufacturer's website, that the technical characteristics to the detection angle (only 240 ° instead of 360 °) are the same. But think! The movable sensor has been replaced by a rigid. So I can not optimally set the detection area. On the website you will find the operating instructions for downloading (the same as here). But still shows the old mobile sensor. The delivered light was settled such manual. Included in this was also a piece of paper with the inscription NEW are shown in the Abdeckmöglichkeiten the sensor into images. Nowhere is described that the sensor is now fixed. I'll keep the light yet, but I am not satisfied with the information from the manufacturer.
