I purchased an older home that has an outdoor light in the middle of the wall at an unusual height. (I'm assuming the intent is to highlight the stairs.) I love this app as it allowed me to see what fit and looked best in this area. (I had 4 I couldn't decide on.) Once I "pictured" my 4 favorites , only one stood out. The sconce is beautiful and easy to install. If your on the fence about wether to purchase this...get it, you'll love it!
