An underwater light, e.g., for a pool or spa, includes an ordinarily watertight housing, an outer compartment within the housing and floodable by water flowing therein in the event the housing is no longer watertight, a current shield within the outer compartment and at least partially defining an inner compartment within the outer compartment, a light emitter within the inner compartment, a passageway communicating between the inner and outer compartments such that outer compartment flood water can enter the inner compartment and contact the light emitter, and a conductor. The conductor is positioned so as to collect stray electrical current conducted from the inner compartment by water within the passageway, thereby reducing the risk of shock presented by such stray electrical current. The underwater light is installable within a wet niche, and includes a transformer housed in a separate compartment that extends into the wet niche for thorough cooling thereof.

A pool or spa system includes networked pool or spa devices that can be dynamically configured with network address by a controller. The controller can transmit a device discovery request on a network and can receive a discovery response from pool or spa devices that require a network address. The system determines and assigns the network addresses for the pool or spa devices based on unique device identifiers associated with the responding pool or spa devices. The network addresses assigned to the pool or spa device are transmitted to the pool or spa device to be used by the pool or spa devices to communicate with the controller over the network. The system can be used to discover and assign addresses to various types of pool or spa devices, such as pumps, underwater lights, chlorinators, water feature controllers, remote controllers, and/or other types of devices.

An LED underwater light, which can be hand-held or mounted on an underwater camera housing, is switchable between two light modes. A first embodiment of the dive light is a focus light, used for initial focusing with a still underwater camera. Incorporated in the focus light is a red light source to which the focus light can be switched from initially projected white light. The switch is used to switch off a series of white LEDs while switching on a series of red LEDs. In a second embodiment, the dive light is a flood/spot light, and enables a diver to quickly switch between flood and spot beams, via separate LED arrays.

A lens for a wet environment lighting device that has a fixture with an interior that has an opening, and at least one light source located within the fixture interior. Light from the light source proceeds out through the opening. The lens is for location in front of the fixture and the light source located therein and the lens encloses the opening from the wet environment. The lens has a first light-directing area for directing light in a first beam pattern. The lens also has a second light-directing area, distinct from the first light-directing area, for directing light in a second beam pattern, distinct from the first beam pattern. The lens is positioned relative to fixture and light source therein to select from the distinct beam patterns based on the alignment of the light-directing areas relative to the light source resulting from a positioning of the lens.
