We purchased three of these pendants to go in our new kitchen. They are beautiful!
1 - They come with differing size rods that can be pieced together to create different lengths. I do not remember the exact number of the different sizes, but there are a few 18", 12", 6" and maybe an 8" as well. Anyway, we did not consider the fact that our pendants would be installed at three different levels of a pitched ceiling. At first we panicked, then we came up with a solution. My husband used his tap and die set, along with a hacksaw, to cut the pieces to fit so all the pendants would be level. Worked like a charm.
2 - LED Edison bulbs really add warmth to a 'cool' kitchen. We have grey cabinets, and SS appliances, so the warmth the bronze and mercury glass add is perfect!
3 - Just print off information of where you got them as everyone will be asking. Or don't. Keep it your little secret and do what I do, tell them they were a special order from Spain and the company is out of business now. Yes they will know you are lying, but they will take the hint and not try and flatter you by copying the look. ha!
