Hans Bergström's Struten (Model 181) is a celebrated pendant lamp that epitomises mid-20th-century Scandinavian design. Introduced in the 1950s and produced by Ateljé Lyktan, the lamp features a distinctive conical shape crafted from white acrylic plastic, reflecting Bergström's commitment to modern, minimalist aesthetics. Struten, commonly known as "the cone," was awarded a gold medal at the 1950 Milan Triennale and is regarded by many as one of Bergström’s most simple yet stylish designs.
