A ceiling-mounted troffer-type light fixture for illumination. The fixture comprises a body with a first flange having at least one hook-receiving opening and a second flange with a suspension-member-receiving opening. A cover includes a rectangular frame, at least one catch-arm and at least one suspension member. Frame fasteners along the frame engage the perimeter in a closed position. One-person attaching/closing and removal of the cover for maintenance is facilitated by the cover being supported in an open position, suspended position and fully engaged with the body in a closed position.
