If 59\" is the maximum fixture height, what would be the minimum height

Actually 59\"/1500mm is the standard overall height of this pendant light. Besides, the cable length is adjustable, so you can lengthen or shorten the overall height within the cable length range by adjusting the pulleys.Or if you want to shorten the net cable length, you could also do it when installation. First, decide the mounting position and the final hanging height of each light, then the cable can be adjusted at the end of attaching the ceiling canopy. Simply cut off the cable to the needed length but please pay attention to allow a bit more left for connection to the supply wires.
