text: These reek of Chinese knock off, but for the price they are okay. I used one to place outside my trailers backdoor. It works in the sense that it is bright and lights up the area, but I was mainly after the motion sensitivity so it would act more like a security/scare light. With my trailer set up in the driveway, free of any obstructions, the light will not trigger until I am up on the stairs. I would have liked to see it trigger 10-15 feet out on approach to the stairs. There is no adjustment for motion sensitivity for this light. The power switch is in a rather inconvenient place (on the back side of the light) which requires me to remove it from the wall to use. Because of this, I used some heavy duty velcro to secure it to my trailers exterior wall. A more permanent installation would not be feasible.
