This ceiling lamp was designed by Salvatore Gregorietti in the 1970s and produced by Luci in Cinisello Balsamo, Italy. It features a disc-shaped fiberglass diffuser suspended within a black metal frame. The fiberglass is shaped into a shallow, undulating form that softens and diffuses the light. The design reflects the use of industrial materials and geometric forms characteristic of Italian lighting design in the 1970s.
