I can not over imply how much I absolutely love these motion sensor lights. I really like this one due to it being a warm white color. It is much less brazan than just the "White" color when your motion turns it on in a dim or dark room. I have these set up in my entry ways and they are so awesome that I would buy them for every entry way that needed light automatically when motion is detected instead of fumbling around to find the light switch. The light is bright and almost instantanious I would say in regards to sensing motion. As soon as I am inside, the light is already on. I do not even see it turn on, I assume from the motion of the door opening turning it on. My dogs and cats are right there to greet me and I can see them right away with out the fear of them running past my legs out of the door before I can turn the acrual light on to be able to catch them. I recommend this to anyone with eye sight, and especially anyone with pets that like to try to escape when you open any door to the outside of your home.
