Installation was very easy (you can look for useful videos on YouTube). There are 3 wires (red, black, and white) that match my lamp post exactly, so there was no guesswork as to which wire went where. My last sensor (different brand) got water in the block where the wires enter the block. As a precaution, I taped the base of the wires with tape. The sensor works very well, turns on at dusk and off at dawn.
