Abstract: An overhead lighting fixture with the housing having an open bottom, a resilient hinge pivotally fastening a first side of the light transmitting panel to a first side of the housing adjacent the open bottom of the housing, and a latch assembly for detachably securing a second side of the light transmitting panel to a second side of the housing adjacent its open bottom. The second side of the housing is an elongated extruded side panel member having a light housing web portion and a latch web portion that lies in a plane approximately 90.degree. thereto. The latch member has a J-shaped configuration with a head, a body, and a foot. The head of the latch member has a circular lateral cross-section that is matingly received in a groove formed in the latch web portion. This structure permits the latch member to be pivoted laterally into and out of engagement with a lip extending along the length of the light transmitting panel that rests in the curved hook surface of the J-shaped latch member.
