We’re very pleased with the chandelier which provides a lot of light in the dining area and is dimmable. While I had some difficulty during assembly of the initial fixture, Wayfair addressed the issue, immediately sending a replacement. I have the fixture 4 stars because the instructions lacked clarity and having to retighten components frequently while assembling. The decorative glass stems are installed last because they add a significant amount of weight to the chandelier. The wires are the same color but identified with tabs marked N (neutral) L (live) and a symbol representing the ground wire. Refer to Wayfair’s description and specs for bulb recommendations, they’re not included in the chandelier’s directions. This item was easy to assemble but did take time screwing and retightening components. Overall, we’re ver happy with our purchase and customer service.
