Took a whole day to install 2 of these. The screws included were not long enough to reach the holes in our electrical box, so we needed to run to the hardware store.  Once we connected the wires, one of the 2 bulbs wouldn't light. Only after moving on to the 2nd did we realize that EACH light bulb had its own wires and needed to be connected. This was not explained in the generic instructions. Finally, one of the exterior screws on EACH fixture separated the head from the screw, necessitating wrestling with pliers.  A VERY frustrating experience.
