The lighting system may have a mounting fixture and a light fixture. The mounting fixture is configured to engage a mounting surface. The light fixture is configured to engage the mounting fixture and has a driver configured to drive a light source. A first fastener having a movable elongated member is configured to removably couple the light fixture to the mounting fixture in an extended configuration. A second fastener having a quick connect feature is configured to removably couple the light fixture to the mounting fixture in a retracted configuration. ## Claims ### Claim 1 A lighting system comprising: a mounting fixture; a light fixture to engage the mounting fixture, the light fixture having a component mounting structure having a first face facing the mounting fixture and an opposing second face facing a light emission end of the light fixture that includes a space containing a light source; a first fastener comprising a flexible elongated member to removably couple the light fixture to the mounting fixture in an extended configuration; and a second fastener to removably couple the light fixture to the mounting fixture in a retracted configuration, wherein an entirety of the first fastener is enclosed within a mounting fixture space between the first face of the component mounting structure and the mounting fixture when in the retracted configuration, the mounting fixture space being separate from the space containing the light source. ### Claim 2 (depends on 1) The lighting system of claim 1, wherein the second fastener comprises a quick connect feature, the quick connect feature having a movable member in one of the light fixture or the mounting fixture, and a recess in the other one of the light fixture or the mounting fixture; and wherein the movable member is movable between an engaged position to couple the light fixture and the mounting fixture, and a disengaged position. ### Claim 3 (depends on 1) The lighting system of claim 1, wherein the light source comprises a light emitting diode (LED). ### Claim 4 (depends on 1) The lighting system of claim 1, wherein the flexible elongated member that provides the first fastener is selected from the group consisting of a cable, a chain, a spring, a push-pull linkage and a combination thereof. ### Claim 5 (depends on 1) The lighting system of claim 1, wherein the mounting fixture space contains at least one of wiring for electrically coupling the light fixture to the mounting fixture, a battery, a battery back up or a combination thereof that is mounted to the first face. ### Claim 6 (depends on 1) The lighting system of claim 1, wherein the second face of the component mounting structure provides a mounting point for a driver to drive the light source. ### Claim 7 (depends on 6) The lighting system of claim 6, wherein the space containing the light source is defined by a diffuser engaged to a first heatsink, the light source is engaged to the first heatsink, and the first heat sink is engaged to the component mounting surface providing an interior space encapsulating the driver, wherein the component mounting surface is a second heat sink. ### Claim 8 (depends on 7) The lighting system of claim 7, wherein the light fixture comprises end caps having slots for engagement to ends of the first and second heatsink, each of the end caps engaged to a first end of the flexible elongated member of the first fastener, wherein a second end of the flexible elongated member is engaged to the mounting fixture. ### Claim 9 (depends on 8) The lighting system of claim 8, wherein the second fastener extends through the end caps of the light fixture to engage the end caps to the mounting fixture. ### Claim 10 (depends on 1) The lighting system of claim 1, wherein the light fixture further comprises: at least one end cap including a motion sensor; and a processing device, wherein responsive to the motion sensor, the processing device is configured to adjust a level of light emitted by the light source coupled to the light fixture between a first non-zero level of light and a second non-zero level of light. ### Claim 11 A lighting fixture comprising: a light source mounted to at least one component mounting structure; a diffuser mounted to the at least one component mounting structure to provide the light emission end of the light fixture; end caps engaged to ends of the at least one component mounting structure and the diffuser to encapsulate the light source; a motion sensor present on at least one of the end caps; and a processing device connected to the at least one component mounting structure configured to adjust a level of light emitted by the light source in response to signals received from the motion sensor, wherein a first fastener comprising a flexible elongated member to removably couple the light fixture to a mounting fixture in an extended configuration, and a second fastener to removably couple the light fixture to the mounting fixture in a retracted configuration, wherein an entirety of the first fastener is enclosed within a mounting fixture space between a first face of the component mounting structure and the mounting fixture when in the retracted configuration, the mounting fixture space being separate from the space containing the light source that is present between a second face of the component mounting structure and the diffuser. ### Claim 12 (depends on 11) The lighting fixture of claim 11, wherein the light source comprises a light emitting diode (LED). ### Claim 13 (depends on 11) The lighting fixture of claim 11, wherein the flexible elongated member that provides the first fastener is selected from the group consisting of a cable, a chain, a spring, a push-pull linkage and a combination thereof. ### Claim 14 An end cap for a light fixture comprising: a housing having an interior surface for engaging at least one end surface of at least one component mounting structure of the light fixture, the at least one of the component mounting structure of the light fixture includes a light source, wherein the interior surface of the end cap includes a receiving structure for a first fastener comprising a flexible elongated member that provides to removably couple the end cap of the light fixture to a mounting fixture in an extended configuration so that the light fixture and mounting fixture are separated from one another, the housing further comprising openings extending through the housing to provide that second fasteners can be traversed through the housing from the exterior surface to removably couple the end cap to the mounting fixture so that the light fixture is engaged to the mounting fixture in a retracted configuration; and a motion sensor engaged to an exterior surface of the housing for the end cap, wherein the motion sensor produces signals indicative of whether a person is in a room in which the end cap is present. ### Claim 15 (depends on 14) The end cap of claim 14, wherein the signals produced by the motion sensor are configured to set a level of light emitted by the light source between a first non-zero level of light and a second non-zero level of light. ### Claim 16 (depends on 14) The end cap of claim 14, wherein a first slot present in the interior surface of the housing engages said at least one end surface of the at least one component mounting structure, and a second slot present in the interior surface of the housing engages a diffuser to provide a space for containing the light source within the light fixture.
