That's irritating.

What about one of those Pottery Barn Edison-type chandelier? It'll look more random and more intentional than three pendants hung off center or swagged over.




Or, do 4-6 recessed lights. One pair on each side of the beam above the island.

I just got two of these lights from Home Depot to install over our kitchen island. Our electrician mentioned that he can easily center them and not have to worry about beams being in the way.

This is a great application for a DC (Direct Current) light fixture application. Step down transformer gets remotely located which gives the designer more options in shallow draft or ceiling mount applications.

Just do three monorail pendants. Then you'll be able to center them.
