Abstract: Devices for producing waterfalls, which provide a decorative effect in pools, spas, bathtubs, and sinks. The devices include a water inlet, and a water chamber connected to the water inlet. An elongated water outlet is connected to the water chamber, such that water exiting the water outlet forms a waterfall-type flow. In one arrangement, a light chamber including at least one lamp is included. The light chamber has a window which allows light generated by the lamp to shine through the water outlet. In another arrangement, the elongated water outlet is provided on an outlet insert, the insert and water chamber having complementary inclined surfaces such that the outlet insert may be positioned at varying distances from the water chamber. In a further arrangement, a plurality of pins are located at the egress of the water chamber, the pins acting as baffles to the flow of water through the device.
