Abstract: A waterfall illuminated by a plurality of optical fibers having their ends disposed along an underside of the edge of the waterfall and directing light downward from the fiber ends onto the surfaces under the waterfall. A fiber optic cable bundle is directed within a fiber conduit along the edge of a generally rectangular water conduit, with the individual fiber ends projecting through respective holes formed in an underside of the fiber conduit. The water and fiber conduits may be located between a wall of a pool or spa and the surrounding coping, with both water and fiber connections being made from the rear portion of the device.
