Honouring the legacy of Poul Henningsen, the PH 3½-2½ Floor Lamp Centenary Edition is based on the iconic three-shade system, the System PH, invented by Poul Henningsen in 1926.Based on this system, Poul Henningsen developed hundreds of lamps as the mathematical principle behind it, made it possible to enable excellent lighting quality for a great variety of purposes. The PH 3½-2½ Floor Lamp Centenary Edition is crafted in aged brass carefully lacquered to preserve the patina, and three shades in an interesting combination of a mouth-blown, four-layered Amber upper glass shade and mouth-blown, three-layered White Opal lower glass shades, all glossy on the outside and sandblasted matte white on the inner side. A great way to provide both a warm, ambient upward light to the surroundings while maintaining a soft diffused and glare-free downward directed light. Combined with a dark brown textile cord, the PH 3½-2½ Floor Lamp Centenary Edition brings a distinct vintage feel to any setting.A contemporary interpretation of the 100-year heritage of the ingenious System PH.
