I love schoolhouse lights and have them in my kitchen and the powder room off the kitchen. I'm not sure about hanging 3 lights though. I know the hallway is 16' long but usually a hallway has one light on the ceiling, centered. Are you going to have a narrow table anywhere in the foyer? You could put a lamp on it for more light or sconces.

Anyway that's just my opinion... not written in stone. ;-)

I don't think you'll need 3 lights in a 15 foot hallway. We had 3 lights in a 30 foot hallway before we got recessed can lights. Our cans are about 5-6 feet apart (same as yours would be in a 15 foot hallway) and it works great for recessed lights but would be too much with dropped fixtures. I think 2 would be fine. IMHO! good luck!

I agree with the other posters. In my 14-foot hallway, the designer recommended 2 fixtures, flush mounted so they wouldn't be too busy (the ceiling is only 8' high).
