I received these lights as a gift because I work late hours and moves into the house at all hours. My husband thought jel would be safer if I had LED night light to illuminate my path on those nights dark and scary. I have just received a few days and I am very happy! We have all placed around the areas that I tend to frequent during my nightly excursions. These lamps are sensational! I think even plug them in my outings outside, which are covered under my vestibule. Normally I would worry about the cost of electricity. However, I was told that it costs less than $ 1 to fund 4 lamps per year! Sure, it's cheap! In addition, there is no need to worry about the light or put out, they have just the right amount of light and it is a very reasonable price!
