The story behind the product: Louis Poulsen's PH 4/3 metal pendant was designed by Poul Henningsen. The pendant saw the light of day for the first time in 1966 and is part of Poul Henningsen's well-known 3 screen system. The system was designed to create a glare-free light that simultaneously cast a calm light and soft shadows. The pendant was originally designed in 1929 and the PH 4/3 is a simplified version of the original lamp. Poul Henningsen designed the 3-screen system in collaboration with Louis Poulsen and designed the first lamps for an exhibition in Paris. The collaboration with Louis Poulsen lasted until his death in 1967.
