Louis Poulsen PH 5 / PH 50 pendant The Louis Poulsen PH 5 and PH 50 pendant light is designed by Poul Henningsen in 1958. The lamp is a very famous and timeless design object. The lamp was created because of the ever-changing shapes and sizes of bulbs by different manufacturers. The layered aluminum design ensures that the light is split evenly and do not seem to shine in the eyes. In 2008, the PH 50 was introduced as a anniversary model for the 50th anniversary of the design that is characterized by 5 colors in high gloss lacquer. The PH 5 is matt lacquered.
