This is a set of two solar-powered outdoor motion-detecting lights. I am using a couple of these in my back patio area. One I have mounted on a fence and one I used the stake to put it in the ground. The motion detection is great, both come on immediately when I open my patio door and throw a lot of light. They stay on for anywhere from 30 seconds to a minute after the motion stops.
The idea is that you place them where they can get as much direct sunlight during the day, which will allow them to come on at night when the motion detection is tripped. The one mounted on the fence gets a lot of light until the afternoon when it is in the shade, and the one in the ground is partially obstructed by my satellite dish but still gets enough light that it works well. They are easy to install and you do not need to do any wiring or drilling (unless you want to mount it to the side of the house). I definitely recommend these and plan to get a couple more.
