Spider Fixed Arms wall lamp is a wall lamp from the French brand Serge Mouille. Designed by Serge Mouille in 1955, it belongs to the “Formes Noires” series, which defines his contribution to twentieth-century lighting design. The structure is based on a wall-mounted half sphere supporting fixed arms of varying lengths, creating an asymmetrical composition. Aluminum reflectors are positioned at the end of each arm and are adjustable through brass ball joints, allowing for directional light. The body is made of steel with brass details and is available in black or white finishes. Spider Fixed Arms wall lamp serves as adaptable wall lighting in living rooms, bedrooms, or workspaces where focused illumination is required. The model is available in configurations with three, five, or seven arms, enabling adjustment of the light distribution depending on the setting. Each piece is numbered and includes a certificate of authenticity.
