Im not sure the mounting plate would fit over the window, how are you planning to power them? do you mean over the shelves?

Gooseneck lights in a dining room were never a historic feature. Imagine sitting at the table with those lightbulbs shining in your eyes.

Are you sold on the orb?

Perhaps something like this? A couple of them installed over the menu sign at a restaurant in NC...

No gooseneck for me.
