I had never seen this type of spotlight. These are powered by solar energy. You place them outside wherever you need the lights to come on due to movement. They can be mounted on the wall or placed in the ground. They come on by motion sensor. This is perfect for where I live. I don’t want the outside lights on all night but I do want the light to come on if someone approaches my place. These are perfect for that. And it saves my energy bill to.
