The lights do not retail for $175., quality wasn’t that good. When I installed the lights on the wall they were all slanted to the right by at least 23 degrees. I had to use a lot of muscle to straighten each one so it was parallel to the wall mount. I am surprised the light fixture arm didn’t break with the pressure I was putting on it. Even loosening the nuts on the back of the wall mount would not straighten the arm.
