so from the first pendant to the third, it is 36 inches? If that is the case I agree with you. Your entire island should be illuminated when using pendants and I can't imagine yours will be.

I don't know about the exact spacing, but maybe center, and out half way from there on each side? I guess, I saying, 1/3 in, middle, and 1/3 again

Wait on an expert or ask a lighting fixture store, not big box store.

Thanks for your comments Debbie. I put the wrong measurements in my post. The island is 9 feet (granite edge to granite edge). The way the wiring it spans the center 36" only.

At 18" apart, your lights are approximately at quarter points, so personally I think that is ideal (from a visual perspective). A friend of mine has a similar size island to yours and has her lights at quarter points. She has 12" pendants and they offer plenty of light for the entire surface. I think the size will depend on the style you select. In my previous kitchen, I had a 60" island with only one pendant centred over the sink. It was perfect for us, as we also had potlights and plenty of sunlight (3 full height windows, w/ patio door).

dndsmom - Your right about the quarter points if it was the 74 1/2" that I originally posted. But that measurement is incorrect. The actual island is 9' granite edge to granite edge. But you have given me a good idea about quarter points. With 108" that would be 27" apart. I'm going to take some string and some paper plates and go across the road and hang these at different intervals to see how they look. Thanks so much for your comments.

Took my paper plates over to the house and hung them to make sure they looked right to me. I kept one centered and then moved out 27" on either side of the center one. Thanks for your help.
