A striking example of Poul Henningsen's pioneering approach to lighting design, this early desk lamp features a tiered shade system constructed from brass and painted copper, mounted on a sleek tubular brass stem. The 4/3 shade configuration reflects Henningsen's meticulous mathematical principles, engineered to diffuse light evenly while eliminating harsh glare. The warm metallic tones of the brass and copper are grounded by the deep, lustrous quality of the Bakelite components, blending functional innovation with an elegant modernist aesthetic.
