We have attached three of the night lights under the open spiral staircase and the landing area itself and are very happy, because one did not has the same need to enable "great light" and still can not run the risk of tumbling down the stairs. However, we need common (after 4-5 weeks at a 1-minute setting) new batteries, as the lights even during the day to tackle (our townhouse staircase has no windows). Nevertheless unrestricted recommendation to buy because just overnight guests are safe at night in the house go.
