Poul Henningsen developed the PH 5 in 1958 in response to constant changes in the shape and size of incandescent bulbs, creating a lamp that could be used with any light source.   The iconic design is based on the same principles as Henningsen’s three-shade system, which ensures that the light is soft, pleasant and completely glare-free, making it the perfect dining room table lamp.   Originally, the PH 5 was fitted with red and blue shades to improve the colour of the light, however these have been removed in later designs as modern light sources reproduce daylight much more effectively than they did in 1958.   Available in a number of different colour variations, the PH 5 is a much-loved and well-known pendant, that is found in many homes around the world.
