Can someone please recommend a good outdoor motion sensor light? We are looking for something that is both attractive and that actually works, and have been having a surprisingly difficult time. We have looked at both Loews and Home Depot, and found the choices to be rather limited. We have already tried a couple different models that did not work well. The lights will need to be mounted somewhat high-up (about 8 feet) on the side of our house along the driveway. Thanks in advance for your recommendations!
