I gave one of these to my sister and put one on our front porch. Usually when we go out during the day, we do not remember to turn the outside light on. You street is pretty dark and it is hard to see to unlock the door. This turns on at dusk. It turns off at dawn. I love the fact that it is LED and will help conserve energy. The light is very blue. I think a lot of people are used to a warmer light. I personally like the lums.
