The fixture is designed based on the principle of a reflective three-shade system, which directs the majority of the light downwards. The shades are made of mouth-blown opal three-layer glass, which is glossy on top and sandblasted matt on the underside, giving a soft and diffuse light distribution.
Born in Copenhagen, Poul Henningsen was an influential character not just as a designer, but as a critic, writer and politician. His ideas were focused on functionality and it was in one of the cold and dark nights of winter that he came up with his signature PH lamp for Louis Poulsen. His designs are characterised by their detailed functionality embedded in culture and societal needs, lending them a timeless aspect.
