Abstract
A lighting fixture arrangement including a lighting fixture suspended from a supporting structure at a first height, and a hanger arrangement located remotely from the lighting fixture and attached to a supporting structure at a second, lower height. The lighting fixture includes a power supply assembly and an optical assembly suspended from the power supply assembly and adapted to receive operating voltages over a cable for operating the optical assembly to illuminate a first area or region beneath the fixture. In accordance with the invention the optical assembly is capable of being removed, or separated, from the rest of the fixture and carried together with its associated cable to the remote hanger arrangement and suspended from the hanger arrangement to illuminate a second area or region beneath the hanger arrangement. The hanger arrangement does not have, and does not require, a power supply assembly of its own, thereby reducing the required mounting space in the vertical dimension.
