A lighting fixture configured to expand and collapse, and methods for expanding and collapsing a light fixture are disclosed. Embodiments of the lighting fixture include a lighting fixture with a movable section that collapses into at least one cavity in a base housing for storage and shipment, and extends from the cavity for operation. In the collapsed configuration the lighting fixture fits into a smaller container than when the lighting fixture is in the expanded configuration. In some embodiments a locking member locks the movable section into its extended position and can be retracted by a user by manually disengaging the locking member. Accessories and extenders that can be attached to the lighting fixture can be stored in the one or more cavities into which the movable section is stowed in the collapsed configuration.

An illustrative light fixture provides an emitter housing and a driver housing in a single fixture with an airflow channel defined between the emitter and driver housings. The airflow channel minimizes thermal conduction between the emitter and driver housings, and maximizes thermal convective cooling for at least one of the emitter housing and driver housing. The emitter housing includes vertical fins extending into the airflow chamber. The left and right sides of the emitter and driver housings define top and bottom edges that are respectively coplanar with the top and bottom edges of the vertical fins.

Apparatuses and methods for accessing luminaire mounting and/or electrical connection compartments and components are disclosed. Embodiments include a front reflective door pivotally attached to a luminaire housing with a closed position covering an opening to the mounting access compartment and an open position allowing easy user access to the mounting feature(s) in the mounting access compartment. In some embodiments the door forms an exterior surface of the lighting fixture, while in additional embodiments the luminaire's light source is mounted on the luminaire housing and not on the door. In still further embodiments the light source is located externally to the mounting access compartment so that the light source is outside the door when the door is closed. In yet further embodiments the free end of the door is adjacent the light source while the pivoting end of the door is located away from the light source.

Example embodiments include modular lighting fixtures and methods for forming the same. Some include light emitters and base members with mounting locations for the light emitters, the light emitters and base members being combinable in varying combinations with each combination producing a different lighting effect. Some embodiments include a light guide, such as a planar light guide, that receives and redirects light from the light emitters. Additional embodiments include a reflector with portions that are positioned near a mounting location where no light emitter is mounted when the reflector is mounted to a base member. Further embodiments include a reflector with portions that are positioned near the mounting locations when mounted to a base member, the portions being easily removed, such as with an unpowered hand tool, to avoid interference with a light emitting member mounted adjacent to where the removable portion would be if not removed from the reflector.
