In the catalog from the years 1928/1929 of the Schwintzer & Gräfe company, various lights designed by Marianne Brandt are exactly described, dimensioned and illustrated. These lights were already mass-produced at that time. Due to the precise information, we were able to restore some of these lights true to the original. Ceiling lamp made of nickel-plated metal, opal glass, outside frosted. Each lamp is numbered consecutively and bears this symbol:TECNOLUMEN / BAUHAUS.
