Abstract: A light assembly includes a light source, a first lens and a first lens holder coupled around the light source holding the first lens in a fixed position relative to the light source. A second lens and a second lens holder are rotatably coupled to the first lens holder holding the second lens optically adjacent to the first lens. The second lens holder and the second lens are rotatable relative to the first lens and the first lens holder.

Abstract: A light fixture has an elongated track comprising an upper channel comprising a first wall having a first slot and a second wall having a second slot. The assembly has a support assembly comprising a base and a swivel arm rotatably attached to the base at a swivel. The base comprising a first flange received in the first slot and a second flange received in the second slot, said base extending across the upper channel. The swivel arm has a first end and a second end. The swivel is disposed at the first end and a cable connector is disposed at a second end of the swivel arm. The cable connector receives a cable therein.

Abstract: A light fixture has a stem with a first portion and second portion disposed at an angle relative to the first portion. The light fixture also includes a housing may include a body cap. The body cap may include an opening receiving the stem therethrough, said housing may include a light source therein. The light fixture also includes a coupler extending from the second portion. The light fixture also includes the body cap rotatable about an axis of rotation defined through the coupler.

Abstract: An assembly for an opening through a member has a body and a first spring retention assembly coupled to the body. The first spring retention assembly has a first coil spring at least partially disposed within a first spring housing. The first coil spring has a first end extending through the first spring housing and is coupled to the body. The first coil spring is extendable from and retractable into the first spring housing.

Abstract: Some embodiments of the present light fixtures include a body, a waveguide, and one or more independently-controllable light sources. The waveguide is configured to be coupled to the body and may include a first end configured to receive light emitted from at least one of the light source(s) and to direct the received light to (and in some embodiments, emit the received light from) a second end of the waveguide. In some embodiments of the present fixtures, the waveguide defines an opening through which light emitted from at least one of the light source(s) can pass, the light source(s) being coupled to the body such that a first one of the light source(s) emits light into the first end of the waveguide and a second one of the light source emits light through the opening.

Abstract: A marine navigational light fixture includes a light source and a cutoff sub-housing holding the light source. The cutoff sub-housing has a main frame having first and second laterally opposite sides; first and second sidewalls projecting from the first and second sides of the main frame, respectively; and first and second cutoff surfaces located on the first and second sidewalls, respectively. The first and second cutoff surfaces are configured to provide practical cutoff of light emitted from the light source outside of a specified arc of visibility. The marine navigational light fixture also includes a main housing holding the cutoff sub-housing. A luminaire subassembly for the marine navigational light fixture includes a colored component having a color that is in the same color family as a color of light emitted from the luminaire subassembly. The colored component can be a lens, a filter cap, a PCB, and/or a telltale.
