Lederam Ceiling Lamps by Catellani & Smith translate the precision of a drawn line into a sculptural lighting collection defined by curved movement, warm illumination, and refined material contrast. Across the C150, C180, and C2 models, softly colored aluminum discs surround ultra-flat LED modules, creating thin, architectural ceiling lamps with a quiet yet expressive presence. The collection includes three ceiling lamp models, each with its own proportion and lighting effect. Lederam C150 features a 50 cm aluminum shade with a 17 cm swiveling disc, offering a compact and elegant composition. Lederam C180 expands the gesture with an 80 cm shade and a 25 cm swiveling disc, creating a broader and more dramatic ceiling presence. Lederam C2 introduces two 17 cm swiveling discs arranged on metal rods, bringing a more dynamic and directional quality to the collection. Crafted from aluminum shades and discs with metal rods and bases, the collection is available in a refined range of finishes, including black with gold leaf, black with copper leaf, white with gold, white with satin, and white with white, depending on the model. Each version delivers warm 2700K LED light with CRI 80, while output ranges from 1,550 lumens in the single-disc C150 and C180 models to 3,100 lumens in the two-disc C2. Designed for 110V or 230V power supply, Lederam Ceiling Lamps bring sculptural Italian lighting, atmospheric warmth, and architectural elegance to living rooms, bedrooms, dining areas, corridors, and refined hospitality interiors.
