Poul Henningsen design for Louis Poulsen, 1926.
The PH 4 ½ - 3 ½ floor lamp, in white opal glass, is both modern and elegant.
The lamp’s design is based on a set of reflective lampshades which, together with its 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 300mm / H 1250mm.
Mouth-blown matt opal glass.
