Claim:
In combination with a spa having a container for holding water with a top rim, the improvement being a waterfall structure comprising: a spout mounted in the top rim of the container, the spout having a narrow and elongated opening between a top lip and bottom lip, the elongated opening being narrower at a symmetrical center between the top lip and the bottom lip than at distal ends of the elongated opening; a plenum chamber having walls, a water inlet and a water outlet, the outlet being connected to the spout, wherein the spout is formed from the walls of the plenum chamber to create a narrow elongated channel leading from the plenum chamber to the spout, wherein the water inlet is a separate part from the plenum chamber that fits into and is permanently fastened to the walls of the plenum chamber, wherein the water inlet further comprises a bottom plate sized to be received within the walls of the plenum chamber to form at least a portion of a bottom surface of the plenum chamber, the bottom plate defining an inlet orifice and having a water pipe connector extending therefrom, and a pair of extended walls extending from the bottom plate, wherein the water inlet further comprises a baffle plate mounted between the pair of extended walls a distance from and a distance over the inlet orifice thereby causing water flowing through the inlet orifice to strike the baffle plate and flow therearound; and a mounting plate extending generally perpendicularly from the spout to attach the waterfall to the top rim of the container of the spa, wherein the mounting plate defines a slot disposed below the bottom lip of the spout and generally parallel to the spout, and a light source mounted within the slot of the mounting plate to inject light directly into the water flowing out of the spout.
