Outdoor lighting really interesting. On the one hand it works with 4 LR20 batteries, easily available commercially. The motion detector is top notch, it is sensitive and triggers the lighting just below a light threshold avoiding unwanted tripping. On the other hand the little templates of the device makes it discreet and Hookable almost everywhere. Also some control dials can adjust the angle of the device relative to his foot but also rotation through another. The power light and very satisfying.
