Edit trying to send this back. How this fixture has this high of a rating, I do not know. I had to try to glue this thing together, even then it was flimsy. While my contractor was trying to install, which took forever since none of the wires are marked, several crystals fel off and broke. Most of the stems remained lose, and wobbled around. Awful quality. 
Looks like it’ll be pretty, but it’s very tedious to put together. The “crystals” are all covered in sticky glue, some I’m having the clean each one. They also don’t all fit. I’ve gotten this far putting it together, so I’ll find a creative solution for making it work. I don’t feel like disassembling and sending it back.
