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. ## Claims ### Claim 1 An expandable high-bay lighting fixture mountable to a ceiling, comprising: an array of lighting elements configured to emit light; a driver electrically coupled to the array of lighting elements and configured to receive power from a building's power source and supply power to the array of lighting elements to illuminate the array of lighting elements; a high-bay driver housing including a mounting surface and housing the driver, the mounting surface configured to mount to a ceiling of the building and permit an electrical connection between the driver and the building's power source; and a lower high-bay housing connected to the driver housing, the lower housing including a top surface and a cavity configured to receive the driver housing, wherein the driver housing is selectively positionable in relation to the lower housing between a retracted position defined by the driver housing being received within the cavity and the driver housing's mounting surface being flush with or below the top surface of the lower housing, and an extended position defined by the mounting surface of the driver housing being extended above the top surface of the lower housing. ### Claim 2 (depends on 1) The expandable high-bay lighting fixture of claim 1, wherein the expandable high-bay lighting fixture defines a collapsed height with the driver housing in the retracted position and an expanded height with the driver housing in the extended position, wherein the collapsed height is approximately one-half (½) the expanded height. ### Claim 3 (depends on 1) The expandable high-bay lighting fixture of claim 1, wherein the lower high-bay housing is rectangular and defines a length, the driver housing forming a central raised portion spanning the length of the lower housing. ### Claim 4 (depends on 1) The expandable high-bay lighting fixture of claim 1, comprising: a locking mechanism configured to automatically lock the driver housing in the extended position when the driver reaches the extended position. ### Claim 5 (depends on 4) The expandable high-bay lighting fixture of claim 4, wherein the locking mechanism includes an actuator configured to disengage the locking mechanism allowing the driver housing to move from the extended position toward the retracted position when the actuator is actuated by a user. ### Claim 6 (depends on 5) The expandable high-bay lighting fixture of claim 5, comprising: a sliding mechanism allowing the driver housing to slide between the retracted position and the extended position. ### Claim 7 (depends on 1) The expandable high-bay lighting fixture of claim 1, comprising: at least one lighting accessory connector positionable in the cavity with the driver housing and dimensioned to be contained within the cavity, the lighting accessory connector being removable from the cavity and configured to connect to the driver housing or the lower housing and provide an attachment location for a lighting accessory. ### Claim 8 A lighting fixture, comprising: an array of lighting elements configured to emit light; a driver housing including a mounting surface and housing a driver configured to power the array of lighting elements, the mounting surface configured to secure to a planar surface; and a lower housing coupled with the driver housing, the lower housing including a top surface facing the driver housing, and a cavity configured to receive the driver housing, wherein the driver housing is selectively transitionable in relation to the lower housing between a retracted position defined by the driver housing being received within the cavity and the driver housing's mounting surface being flush with or below the top surface of the lower housing, and an extended position defined by the mounting surface of the driver housing being extended above the top surface of the lower housing. ### Claim 9 (depends on 8) The lighting fixture of claim 8, wherein the lighting fixture defines a collapsed height with the driver housing in the retracted position and an expanded height with the driver housing in the extended position, wherein the collapsed height is approximately one-half (½) the expanded height. ### Claim 10 (depends on 8) The lighting fixture of claim 8, wherein the lower housing is rectangular and defines a length, the driver housing forming a central raised portion spanning the length of the lower housing. ### Claim 11 (depends on 8) The lighting fixture of claim 8, comprising: a locking mechanism configured to automatically lock the driver housing in the extended position when the driver reaches the extended position. ### Claim 12 (depends on 11) The lighting fixture of claim 11, wherein the locking mechanism includes an actuator configured to disengage the locking mechanism allowing the driver housing to move from the extended position toward the retracted position when the actuator is actuated by a user. ### Claim 13 (depends on 12) The lighting fixture of claim 12, comprising: a sliding mechanism allowing the driver housing to slide between the retracted position and the extended position. ### Claim 14 (depends on 8) The lighting fixture of claim 8, comprising: at least one lighting accessory connector positionable in the cavity with the driver housing and dimensioned to be contained within the cavity, the lighting accessory connector being removable from the cavity and configured to connect to the driver housing or the lower housing and provide an attachment location for a lighting accessory. ### Claim 15 A lighting fixture, comprising: a driver housing including a mounting surface and housing a driver configured to power an array of lighting elements, the mounting surface configured to mount to a planar surface; a lower housing coupled with the driver housing, the lower housing including a top surface facing the driver housing, and a cavity configured to receive the driver housing; and a locking mechanism; wherein the driver housing is selectively positionable in relation to the lower housing between a retracted position defined by the driver housing being received within the cavity and the driver housing's mounting surface being flush with or below the top surface of the lower housing, and an extended position defined by the mounting surface of the driver housing being extended above the top surface of the lower housing; wherein the locking mechanism is configured to automatically lock the driver housing in the extended position when the driver reaches the extended position. ### Claim 16 (depends on 15) The lighting fixture of claim 15, wherein the lighting fixture defines a collapsed height with the driver housing in the retracted position and an expanded height with the driver housing in the extended position, wherein the collapsed height is approximately one-half (½) the expanded height. ### Claim 17 (depends on 15) The lighting fixture of claim 15, wherein the lower housing is rectangular and defines a length, the driver housing forming a central raised portion spanning the length of the lower housing. ### Claim 18 (depends on 15) The lighting fixture of claim 15, comprising: a locking mechanism configured to automatically lock the driver housing in the extended position when the driver reaches the extended position. ### Claim 19 (depends on 18) The lighting fixture of claim 18, wherein the locking mechanism includes an actuator configured to disengage the locking mechanism allowing the driver housing to move from the extended position toward the retracted position when the actuator is actuated by a user. ### Claim 20 (depends on 19) The lighting fixture of claim 19, comprising: a sliding mechanism allowing the driver housing to slide between the retracted position and the extended position.
