Poul Henningsen designed the three-shade system back in 1925-1926. The first lights using the system were designed by PH in cooperation with Louis Poulsen for an exhibition in Paris. This partnership continued up until his death in 1967. Throughout his life, PH sought to create glare-free light, direct light where it was most needed, and create soft shadows, using incandescent bulbs as a light source.
