The ceiling light fixture portion has a lip projecting upward at an edge. The diffuser frame includes a torsion spring latch mounted on a first inner surface the diffuser frame and supporting tongues mounted on a second inner surface of the diffuser frame. The torsion spring latch can be latchingly connected to the ceiling light fixture for holding the diffuser frame in a closed position in which the diffuser and diffuser frame substantially enclose the ceiling light fixture with the diffuser frame generally abutting the ceiling.
