I am so happy to have these wireless motion sensor lights. They came with three lights in a package so they are excellent for landscaping, stairs, or anywhere you need some lighting that are bright and come on when they detect motion from quite a distance. They are operated by AA batteries and these are not included however I mounted mine on stairs outside and they are still working just as bright as the first time they came on. I love that they light up bright so I do not stumble up the stairs after dark. These are great lights. They are not very big which make them versatile to be used wherever you need them and they are very bright. I definitely would recommend these lights.
