Small diameter ceiling pendant for exposed beams?

[cadspark]

Hi guys,
Im looking for a standard white 6 inch pendant with as narrow a diameter as possible to avoid the overlap on a property with exposed beams. Doesn't have to be 3 plate as i'm wiring at switch. Any ideas which are smallest and where to buy would be greatly appreciated.
