The wireless battery-powered LED bollard is equipped with motion detectors. The lamp can be used indoors and outdoors. Unfortunately, the manual is in English only and then you have them also on the PC. Ichpersönlich find this very inconvenient and not for everyone. The setting of the light sensor can be set only 20 seconds or 5 minutes. As the bollard is delivered without battery, you have to get the right batteries once. Inserting the batteries is relatively simple. I have the bollards in a cottage attached to me in the stairwell where they also work well. Very handy, because not a power connection is required by the battery. The motion sensor works well and also very fast as it promises the product. I am satisfied with the bollard, precisely because it fulfills the functions that I have hoped for. However, the price is still quite high, because the product consists only of plastic. Still to recommend a good product and to purchase for me.
