Abstract: Water-powered lighting systems for use in connection with baths, spas and the like are disclosed. Some embodiments disclosed herein provide a water-powered lighting apparatus including a light fixture having a housing, wherein an electrical generator is disposed in the housing. The electrical generator may include a turbine wheel configured to be rotated by flowing water coming in contact therewith, such as water flowing in a water-jet piping system of a bath or spa. The electrical generator may provide energy used to power one or more light sources of the lighting system, thereby providing lighting to a target area. Certain embodiments disclosed herein may allow for lighting of a bath or spa without the need for electrical wiring, such as by using power provided by a water turbine generator.
