Groupage square LED ceiling light - design by Ernesto Gismondi The construction of the Groupage LED ceiling light is based on a very simple mechanical approach and ensures excellent light emission. The light can be used individually or combined in several units of the same or different sizes and operated together - depending on the lighting task. The highly reflective white reflector and the opal plastic cover create homogeneous area lighting; the design with a cuboid aluminium body fits into any interior. Ernesto Gismondi was the founder of the Italian lighting label Artemide. From the early 1960s, he devoted himself to the planning and production of lighting equipment and, together with the designer Sergio Mite, founded the Artemide Studio, from which the Artemide Group emerged, which is now recognised worldwide as a producer of high-quality lights.
