Abstract: Disclosed is a method of determining depreciation of a lumen output of an LED. More particularly, disclosed is a method of determining depreciation of a lumen output of an LED comprising monitoring, by a processing device, an operating characteristic of an AC power source operatively coupled to the LED; determining, by the processing device, whether a lumen output the LED depreciated beyond a specified lumen value based on the monitoring; and causing, by the processing device, an indicator to provide notification to a user based on determining the lumen output of the LED depreciated beyond the specified lumen value.

Abstract: The present disclosure relates to a lighting fixture for use in connection with a swimming pool or spa. The lighting fixture includes a light source, and a detection device for detecting the presence of a bather in a pool or a spa. A microprocessor is in electrical communication with the detection device and the light source.

Abstract: A light includes a body, a front housing secured to a front end of the body, a translating retainer rotatably engaged with the front housing, a slip ring positioned around the front housing and between the translating member and the front end of the body, a compressible ring positioned around the front housing and between the slip ring and the front end of the body, a lens mounted to the front housing, an electronic assembly, and a light emitting element in electrical communication with the electronic assembly and positioned within the lens. Rotation of the translating retainer in a first direction causes the translating retainer to drive the slip ring toward the front end of the body, compressing the compressible ring and causing the compressible ring to bulge outward to contact, and removably engage, an inner wall of a pipe or conduit that the light is positioned in.

Abstract: A self-priming dedicated water feature pump is provided. The water feature pump can include a strainer housing connected to a pump housing. The strainer housing can include a reservoir for allowing water to enter the strainer housing so that the pump can self-prime. The strainer housing can also include a post installed within the reservoir. The post can function to prevent a strainer basket from being installed in the strainer housing. The post can be of sufficient volume and/or geometry to allow enough water to enter the strainer housing so that the water feature pump can self-prime while also preventing a strainer basket from being installed in the strainer housing.

Abstract: A system and method are provided for controlling water temperature in a body of water. The temperature control system includes a processor, a user interface for receiving a desired temperature and a desired time for reaching the desired temperature, a sensor interface for receiving sensor information from one or more sensors, and an actuator interface for controlling a plurality of heat sources. The processor determines one or more optimal heat sources for heating the body of water to the desired temperature by the desired time. The processor controls the one or more optimal heat sources through the actuator interface and periodically polls the sensor interface to determine whether changes in the operating environment require additional or alternate heat sources to be activated to ensure that the body of water is heated to the desired temperature by the desired time.

Abstract: Power supplies for pool and spa equipment are disclosed. In one embodiment, the power supply includes a buoyant housing, a peripheral float, at least one solar cell positioned on the buoyant housing for collecting sunlight and converting same to electrical energy, and a power cable for interconnecting the power supply and pool/spa equipment. In other embodiments, first and second inductive power couplings are provided for powering pool and spa equipment. The power couplings can also be installed using existing plumbing features of the pool or spa.

Abstract: The present disclosure relates to a programmable underwater lighting system for pools and spas. A plurality of underwater lights, each having a plurality of LEDs for producing light of various colors, a microprocessor for controlling the plurality of LEDs, and a memory in communication with the microprocessor containing one or more stored control programs, allow for the generation of various lighting effects in a pool or spa. A central controller is provided in communication with the plurality of underwater lights, and allows a user to define or select a desired lighting effect (such as a sequence, a fading effect, a “moving” color pattern, etc.) using a display and a keyboard. Optionally, a handheld remote control could be provided, in wireless communication with the central controller, for allowing a user to remotely control the plurality of lighting fixtures.
