I usually leave extra slack on the wires for chandeliers in case the homeowner decides to lower it or use it on a high ceiling in the future. Having the deep octagon electrical box in the ceiling lets me tuck some extra chandelier wire slack up there.
White electrical tape was put on the chandelier neutral conductor to make it easily identifiable. Normally shallow ridges on the one side indicate the neutral.
