Poul Henningsen design for Louis Poulsen, 1926.
The PH 3 ½ - 2 ½ floor lamp’s design is based on its set of reflective lampshades which, together with its light anti-glare disk, create pleasant glare-free light.
The system is based on a logarithmic spiral, with the focal point of the light source situated at the center.
The 3 layers of hand blown opal glass, polished on the upper side and sandblasted on the inner side, let out soft and diffuse light.
The dimensions of the lampshade have a ratio of 3:2:1, thus homogeneously reducing the quantity of light emitted.
Ø 330mm / H 1300mm.
Matt white opal glass. High lustre chrome plated.
