Abstract: A low profile, lighted waterfall apparatus for producing a sufficiently lit artificial waterfall having a light source chamber, distal to a waterfall slot/primary outlet and substantially aligned on the same plane therewith, and a port for accessing the light source, such that the light source can be easily accessed, inserted, removed, and/or replaced. The light source chamber having a transparent, semi-transparent, or translucent divider to shine light towards and across the waterfall slot/primary opening via a grooved spreading manifold/area/passage. The grooved spreading manifold/area/passage configured to spread the flowing water, and direct the water as a fluid wave guide towards the waterfall slot/primary outlet.

Abstract: A system for jet hydrotherapy configured to produce a fluid jet from an aerated fluid flow at sufficiently high velocities/pressures for massage or therapeutic treatment, which is accomplished by an internal geometry that places, at least, fluid and gas orifices, vessels and nozzles in the optimum location and configuration to create high fluid flow velocities throughout the system. The system also is configured to produce a fluid jet with sufficiently high gas content such that a user experiences less discomfort and/or pain when the fluid jet is applied to sensitive tissue areas. The system also is configured to provide a tactile interface upon which a system user can mechanically engage to supplement the jet hydrotherapy.

Abstract: A clip and system for providing light to a spa feature, having a clip for holding a light emitting device and a spa feature having a housing connector, the spa feature and the housing connector being manufactured at least in part from a clear material and having a connector allowing the attachment of the clip to the spa feature, the clip having a support structure for containing and/or supporting the light emitting device and a clip connector for attaching the clip to the spa feature.

Abstract: A waterfall waterjet that can be attached to a spa, with at least one chamber, at least one primary outlet, at least one debris outlet that can be opened and closed, and a water source fluidly connected to the waterfall waterjet.
