Well, unfortunately, my barn lights were defective when they arrived.  The metal "bar" that connects the light fixture to the wall plate was bent in an awkward way so that the fixture was pointing toward the wall rather than toward the ground.  The good news is that customer service was great to work with and went ahead and ordered two new barn lights for me.  I encouraged them to inspect the fixtures before shipping them to me in case you had received a bad batch from the manufacturer.  They have not yet arrived.  D. Maloy
