An apparatus configured to indicate a length of extension for screws extending from a bracket, comprising (A) a first portion at one end, (B) a second portion having a depth, (C) a third portion having a length, (D) a fourth portion having the depth and (E) a fifth portion at another end. The first portion may be connected perpendicularly to the second portion. The second portion may be connected perpendicularly to the third portion. The third portion may be connected perpendicularly to the fourth portion and away from the first portion. The fourth portion may be connected perpendicularly to the fifth portion and away from the first portion. The depth offsets the third portion from the first portion and the fifth portion by a distance equal to a thickness of a base of a light fixture plus a depth of a locking nut for the screws.

A light fixture includes a heat dissipating structure, an electronics assembly, and a bolt for attaching the heat dissipating structure to an external panel. The heat dissipating structure includes a first side having multiple outwardly extending projection regions and a socket, for receiving a light source, is formed in an apex of each projection region. A second side of the heat dissipating structure includes a heat sink formed in an internal cavity of each projection region. The heat sink includes fins in contact with and radially arranged about an outer surface of the socket. The electronics assembly is located at the first side of the heat dissipating structure. The bolt includes a passage through which wiring from an external source is routed to the electronics assembly. The electronics assembly includes wires routed through channels in each of the projection regions that electrically interconnect the light sources to the electronics assembly.

A luminaire comprising a housing formed of thermally conductive polymer with an optic carried thereby, a trim carried by the optic, and a light source. The light source may comprise an LED board comprising a copper layer and a plurality of light emitting diodes (LEDs) disposed on the LED board. The luminaire may also comprise control circuitry operably coupled to the plurality of LEDs, wherein the LED board is positioned in thermal communication with the housing. The luminaire may further comprise a mounting member configured to be attached to each of the housing and an external structure. The control circuitry may be configured to operate the plurality of LEDs such that heat generated by the plurality of LEDs is dissipated by the copper layer of the LED board.

A lighting fixture can be mounted to a structure near an obstacle that may constrain mounting options for the lighting fixture. An adjustable bracket can facilitate mounting the lighting fixture closer to the obstacle than would be workable without the adjustable bracket. A portion of the adjustable mounting bracket can translate rotationally and linearly. Using the translation capability, an installer can move the portion of the bracket away from the obstacle to provide room for attaching the fixture to the bracket. Once the fixture is attached, the installer can readjust the bracket to provide a long-term operating position, or the installer may leave the lighting fixture in a translated position relative to the bracket.
