From the description you link, it says they have a minimum hanging height of 30.5. If your island is standard 36" high you'll have 29.5" at most between counter top and bottom of pendant. They sound big, but without seeing a picture or floorplan or knowing your height, we don't know how they'll impact sight lines etc. If this is your existing house, I'd do a test run by blowing up a couple of balloons to about the same size and hanging them on strings to the minimum hanging height. That's how I tested for a new fixture in my old house. I moved the table under it and we had dinner to see how the height of the globes felt.

In general, I think they are fine. Larger pendants are more acceptable now. Especially with them being mostly transparent, they won;t have a heavy feel.

Can you post a photo of the space?

Thanks. The space is pretty much in demo mode right now. Waiting for my cabinets/island to come in. I need to return the lights within 30 days if I don't want them. I think I purchased them pre-maturely. I will post when the island is in. thanks again.
