One Swivel Arm reading lamp is a wall light from the French brand Serge Mouille. Designed by Serge Mouille in 1954, the model belongs to the Formes Noires series and represents a simple and functional approach to directional lighting. The fixture is mounted on a round wall plate with an integrated switch, from which a straight arm extends and swivels horizontally from side to side. The reflector is attached via a brass ball joint, allowing precise adjustment of light direction. The structure combines a steel body with an aluminum reflector, finished in black or white with contrasting brass details. One Swivel Arm reading lamp is suited for bedside use, seating areas, or smaller workspaces where an adjustable light source is required. The straight arm provides controlled light output. Each piece is manufactured in France according to the original drawings and issued as a numbered edition with a certificate of authenticity.
