These lights really shine bright and outlast the other lights I have used. You can place them wherever you need them and they do an amazing job. I placed two down my staircase and then I placed another at the very top and it works like a dream. I walk by and the light the way and note I don't have to worry about my daughter tripping down dark stairs. This really is a necessity for anyone who has stairs.
