Poor directions, which call for a headless screw, which was not included in the hardware. The bit included 6/32 screw with a head and it should have been an 8/32 without a head. The wires were both black, and the directions indicated there was a white and a black wire. It was very difficult to determine which wire was the neutral wire. The staples that hold the diffuser up look "tacky." There should be a rim or something more decorative holding the diffuser up. I expected a better quality light for the price.
