We purchased two of these lights to place on the front of our garage. The lights were easy to install and program. We've had the lights for two weeks now and couldn't be more pleased. We use 100 watt incandescent bulbs, which assure the dual-bright function works. The lights accent the front of our home until the motion sensor picks up movement. Then, the lights bump up to full wattage for 5 minutes (but you could disable this function or set it for 1 minute, if you like). We've received several compliments from our neighbors, not only for the function, but also for the design of the lights. Great purchase!
