I purchased 3 of these to coordinate with the French Empire Collection 14 light Chrome Finish with Clear Crystal Chandelier 20" x 26" because the bottoms of the sconces have the same crystal balls, so they match well.
They have incandescent bulbs, so they are dimmable, and they install easily. The trade off in price it is completely assembled by your installer, save for the frame. All the crystal strands have to be linked together, whereas a more expensive light might have them partially assembled. If you can tolerate that, it's a good buy.
The crystal in my sconces tended to be more of a white fire, so the colors aren't as brilliant as the chandelier, however, they are still eye-catching and will add a touch of glam-sophistication.
