Installed a pair of 15" lights at the front door. They illuminate quite a bit of light (that may be good/or bad) depending on your use. I had to change the size of the mounting pad(s) on the house however I knew this going into the install.  Installation was straight forward. Notes: The lights were delivered quickly and packaged well. The lens appears to be glass and is fairly heavy but looks nice. I gave 4 stars because they are made in China and I question their longevity. If they last (especially through a harsh winter) it will be a 5 star rating.
