There is described a lighting panel for a drop ceiling of the type in which a plurality of T-frame members are arranged in a grid, forming a pattern of rectangular openings with ceiling panels supported in the openings by the grid. The lighting panel has an outer frame which is slightly smaller than one of the openings, with a light diffusing panel mounted in the frame. The frame is supported from the grid frame members by a pair of support members that project from the outer frame at opposite ends of one side, the projecting support members allowing the one edge of the outer frame to be supported with the panel in a vertical position. The panel is rotated up into a horizontal position within the grid opening and latch means secures the free edge of the outer frame to the grid frame member to hold the lighting panel in place.
