We just bought a house with lots of stairs. These work awesome to light up the area at night. We have 3 kids here so it is nice to have them come on as they are approaching and coming down the stairs without needed to turn a light on. They are really bright and adhere to the wall nicely. We chose to use the adhesive tape to see how that would work before we screwed them in. It has help up well so far. I am going to purchase more to use in the kitchen under the cabinets.
