The PH 3/2 is a beautiful lamp from lighting company Louis Poulsen and designer Poul Henningsen. As so often with Poul Henningsen's lamps, the PH 2/1 consists of the familiar three-shade system, which was designed back in 1925-1926. It is reflective, sending the majority of the lamp's light downwards. The lampshades are made of mouth-blown opalised three-layer glass, which is glossy on the outside but sandblasted and matt on the inside. The result is a soft and diffused light that works well in living rooms, hallways, kitchens and offices. See more Louis Poulsen wall lights here
