I hired a certified electrician to hang pendants. He had to reconfigure the wiring in order to hang the pendants. He had no way of fixing the fact that they hang crooked. The glass is very difficult to clean. The globes can not be disconnected so you must clean them as they hang. I regret getting clear glass. I’m going to get Edison bulbs today. Based on the price I paid, I wish I got better quality. My husband wanted me to return them but I didn’t want to deal with that and I had the electrician at the house to do the job.
