Starting from the necessity of illuminating the faces reflected in the mirror of a cabinet designed for the famous French glassworks Boussois, in 1965 Charlotte Perriand designed the wall-mounted version of the Lampe de Bureau. The body features grey tones, while the translucid pressed glass diffuser is available in the finishes green, red, blue mare, blue grey, yellow and matte white outside. On the inside the white finish preserves the natural colour of the light. For flexible positioning of the light, a 120-degree rotation of the body is provided.
