Original PH 80 Middle Shade for the classic PH 80 lamp designed by Poul Henningsen.
The PH 80 emits a diffused light. The majority of the light is directed downwards by the acrylic shades, which also help to emit the light horizontally and upwards. The shade design is based on a logarithmic spiral, with the focal point of the light source located in the center of the spiral. The red color of the top reflector helps provide a warm light.
