-20. (canceled)
An apparatus, comprising:
- a casing formed of injection molded plastic, the casing comprising:
- a sidewall surrounding a cavity having a vertical height and adapted to contain a light source module in the cavity, the sidewall having an edge defining an opening;
- and
- a closed top end coupled to the sidewall and at an opposite end of the cavity from the opening, the closed top end including a first plurality of wiring passageways, wherein the vertical height of the cavity of the casing is sufficiently large to contain:
- all of the light source module;
- a substantial portion of a crown of a trim coupled to the light source module;
- at least a portion of a first pair of building electrical power wires to supply power to the light source module;
- and
- at least a portion of a second pair of building electrical power wires to supply the power to another light source module of a nearby lighting unit.

An apparatus, comprising:
- a casing formed of injection molded plastic, the casing comprising:
- a sidewall surrounding a cavity and adapted to contain a light source module and building electrical power wires in the cavity, the sidewall having a first end and a second end, the first end having an edge defining an opening;
- and
- a closed top end, coupled to the sidewall, to cover the second end of the sidewall;
- and
- a casing holder directly coupled to the sidewall and not coupled to the closed top end such that the casing holder is slidably adjustable with respect to the casing and not rotatably adjustable with the respect to the casing.
3 more elements
An apparatus, comprising:
- a casing to contain a plurality of building electrical power wires, the casing comprising:
- a sidewall surrounding a cavity and having a substantially regular octagonal cross section, the sidewall having a first edge at least partially defining a first opening at a first end of the cavity and a second edge at least partially defining a second opening at a second end of the cavity;
- a closed top end, coupled to the sidewall, to cover the second opening at the second end of the cavity, the closed top end having a shape that substantially conforms with the octagonal cross section of the sidewall;
- a plurality of knockouts disposed on the sidewall and the closed top end;
- and
- a frame disposed in the cavity and accessible via the first opening at the first end of the cavity, the frame having an inner edge and a frame opening surrounded by the inner edge of the frame, wherein the inner edge is circular, oval, or curved.
3 more elements
An apparatus, comprising:
- a casing having a cavity to contain a light source module, the casing comprising:
- a sidewall surrounding the cavity and having an octagonal horizontal cross section, the sidewall comprising:
- a bottom edge defining a bottom end opening through which light emitted by the light source module exits the housing;
- a top edge defining a top end opening;
- a first sidewall opening on a first side of the sidewall;
- a second sidewall opening on a second side of the sidewall located diametrically opposite from the first side;
- a tab, joined to the top edge of the sidewall, having a flat portion covering a portion of the top end opening;
- a closed top end, coupled to the sidewall via a fastener inserted through a first fastener opening in the closed top end and a second fastener opening in the tab of the sidewall, to enclose the top end opening by covering the top edge of the sidewall, the closed top end having a shape that substantially conforms with the octagonal horizontal cross section of the sidewall;
- and
- a plurality of knockouts disposed on the sidewall and the closed top end, the plurality of knockouts comprising:
- a first knockout disposed on a fifth side of the sidewall proximate to the top edge of the sidewall;
- a second knockout disposed on a sixth side of the sidewall proximate to the top edge of the sidewall, the sixth side being located diametrically opposite from the fifth side of the sidewall;
- a third knockout disposed on a seventh side of the sidewall proximate to the top edge of the sidewall;
- and
- a fourth knockout disposed on the closed top end,
- wherein:
- each knockout in the plurality of knockouts is substantially circular in shape with a diameter greater than 0.5 inches;
- and
- the casing is formed of galvanized steel.
