First Impression: TaoTronics Intelligent Safety LED Sensor Light. After opening the package you come first to a really detailed instruction manual with the most important points are displayed as images in German, French. The lamp can be at no time with no problems instalation. Supplied with plugs and screws are included. The light is more than adequate. Functionality: The instrument sees through the dull dark green housing made of super and does not fall directly on. The finish is clean and tidy, as you are used to it from TaoTronics. The lamp is operated with 4 x D batteries. Can also be operated with batteries. Klein, while a bright light. Light output is 300lm. Bottom line: After some time in continuous use, I can only write good. I have installed the sensor light in the tree. For a battery-powered lamp with motion sensor I was really surprised. Have a directly ordered. Of course, not to be compared with one without battery. Price performance is good. So from me full 5 stars.
