Three Arm, One Curved Rotating Arm ceiling lamp is a ceiling light from the French brand Serge Mouille. Designed by Serge Mouille in 1956, the model belongs to the Formes Noires series and combines fixed and movable elements in an asymmetrical structure. The fixture is mounted on a round ceiling base from which a vertical tube extends into a rotating curved arm. From this arm, two fixed straight arms emerge in a V-shape, creating a balanced composition. Each arm ends with a reflector that can be adjusted using brass ball joints, allowing precise control of light direction. The structure combines a steel body with aluminum reflectors, while brass details create contrast in black or white finishes. Three Arm, One Curved Rotating Arm ceiling lamp is suited for interiors where flexible lighting is required and is particularly effective in corner placements. The configuration allows variation in light distribution. Each piece is manufactured in France according to the original drawings and issued as a numbered edition with a certificate of authenticity.
