• a socket disposed within said narrow neck opening toward said bulbous body and sized to receive the base of a lamp;
• and
• a locking component that is securable to said narrow neck for fixedly securing said luminaire housing to a mounting member having an opening into which said outer end of said neck is inserted, the mounting member opening located between said locking component and said bulbous body.

A canopy luminaire adapted for installation by a single individual comprising:

• a luminaire housing having a bulbous body configured to receive the light-emitting section of a lamp and a narrow neck extending therefrom with an inner end connected to said bulbous body and an outer end;
• a vertically oriented socket disposed within said narrow neck opening toward said bulbous body sized to receive the base of a high intensity discharge lamp;
• a pair of spring clips, each of said spring clips having an upper end secured to said outer end of said narrow neck and a lower end extending downwardly and biased outwardly from said narrow neck for securement of said luminaire housing to a horizontal mounting member having an opening into which said outer end of said neck is inserted, said spring clips secured on opposing sides of said narrow neck and wherein said lower end of said spring clips is spaced above said bulbous body a distance sufficient to receive said mounting member therebetween;
• and
• threads on said inner end of said narrow neck adapted to receive a threaded nut for fixedly securing said luminaire housing to the horizontal mounting member with the mounting member opening located between said nut and said bulbous body, said threads including a plurality of threaded segments spaced circumferentially about the lower end of said narrow neck and wherein each of said spring clips extends downwardly into a gap formed between said segments, said lower end of each of said spring clips biased outwardly beyond an outer surface of said threaded segments.

A canopy luminaire adapted for installation by a single individual comprising:

• a luminaire housing having a bulbous body configured to receive the light-emitting section of a lamp and a narrow neck extending therefrom with an inner end connected to said bulbous body and an outer end;
• a vertically oriented socket disposed within said narrow neck opening toward said bulbous body sized to receive the base of a high intensity discharge lamp;
• a pair of spring clips, each of said spring clips having an upper end secured to said narrow neck and a lower end extending downwardly and biased outwardly from said narrow neck for securement of said luminaire housing to a horizontal mounting member having an opening into which said outer end of said neck is inserted, said spring clips secured on opposing sides of said narrow neck and wherein said lower end of said spring clips is spaced above said bulbous body a distance sufficient to receive said mounting member therebetween;
• and
• a frustro-conical clamp for fixedly securing said luminaire housing to the horizontal mounting member with the horizontal mounting member opening located between said clamp and said bulbous body, said clamp having an upper end, a lower end, and an opening therebetween sized to receive said narrow neck, said upper end adapted to be secured to said narrow neck by a plurality of threaded fasteners and said lower end including an outwardly extending annular flange for engaging the horizontal mounting member when said upper end is secured to said narrow neck.

A method of enabling a single person to install a canopy luminaire in a horizontal mounting member, said canopy luminaire having a luminaire housing with a bulbous body configured to receive the light-emitting section of a lamp and a narrow neck extending therefrom including an inner end connected to said bulbous body and an outer end, and a spring clip having an upper end secured to said narrow neck and a lower end extending downwardly and biased outwardly from said narrow neck, said lower end of said spring clip being spaced above said bulbous body, comprising:

• forming an opening having a periphery sized to receive said narrow neck in a horizontal mounting member;
• inserting said outer end of said narrow neck of said luminaire housing upwardly into said opening in the horizontal mounting member, said periphery of said opening engaging and deflecting inwardly said spring clip;
• extending said neck upwardly through said opening until said spring clip emerges above and beyond said mounting member such that said spring clip is biased toward its undeflected shape;
• and
• supporting said luminaire housing from said mounting member by said spring clip.

A method of changing the lamp of a canopy luminaire, said canopy luminaire having a luminaire housing with a body configured to receive a lamp, a spring clasp secured to said body at a first end, a glass lens attached to said body at a second end opposite said first end by a hinge to permit said glass lens to swing between an open position and a closed position and including a latch for releasable engagement with said spring clasp, and a handle secured to said glass lens for opening and closing said glass lens, said method comprising:

• providing a lamp changing pole having a C-shaped hook;
• providing a lamp changing pole having a lamp gripper;
• engaging said handle with said C-shaped hook;
• moving said pole downwardly to release said latch from said spring clip;
• supporting said handle in said hook while swinging said glass lens to said open position;
• disengaging said hook from said handle;
• engaging said lamp with said lamp gripper;
• removing said lamp with said lamp gripper;
• inserting a second lamp with said lamp gripper;
• disengaging said lamp gripper from said second lamp;
• engaging said handle with said hook;
• supporting said handle in said hook while swinging said glass lens to said closed position;
• and
• releasably engaging said latch in said spring clasp.

A canopy luminaire comprising:

• a luminaire housing having a base with a periphery including a stop extending therefrom;
• a shelf having a wall extending from said periphery of said base and a floor having a recess formed therein, said shelf and said periphery of said base forming a channel;
• and
• a lens having a foot including a detent extending therefrom, said foot sized to be slidably received in said channel to support said lens in said shelf, said foot engaging said stop to limit the sliding movement of said foot in said channel and said detent operatively engaging said recess in said floor to releasably hold said lens to said base.

A method of releasably securing a glass lens to a canopy luminaire comprising:

• providing a luminaire housing having a base with a periphery including a stop extending therefrom and a peripheral groove formed therein, a shelf having a wall extending from said periphery of said base and a floor having a recess formed therein, said shelf and said periphery of said base forming a channel, and a gasket secured in said peripheral groove;
• providing a lens having a foot including a detent extending therefrom, said foot sized to be slidably received in said channel to support said lens in said shelf;
• placing said foot of said lens against said gasket,
• deforming said gasket with said foot,
• rotating said glass lens in a first direction until said foot contacts said stop and said detent is received in said recess;
• releasing said glass lens;
• and
• supporting said foot in said channel.
