After hanging the light fixture we found out that one of the sockets wasn't working. We initially thought it was something we did wrong so we hired an electrician and he noticed that a tiny screw in the socket was missing. He removed a tiny screw from another part of the light and rigged the light. They light is beautiful and looks more expensive than they way it was made. If possible, I would recommend testing the sockets before hanging the light and confirm all the parts are included.
