Design by Poul Henningsen, 1926.
By Louis Poulsen.

PH 3/2 is a member of the PH 3-shade family originally conceived in the winter of 1925-26 for a large exhibition hall in Copenhagen, Denmark called "Forum" and is based on the principle of a reflecting multi-shade system, creating a harmonious and glare-free illumination. The shades are drawn over a logarithmic spiral, with the center of the light source placed in the spiral's focal point.

White opal handblown glass shades which have been sandblasted on the undersides for uniform light distribution. Black chrome or high-luster chrome-plated spun brass suspension. White ceiling canopy which mounts to a 4" octagonal junction box. 12 foot long 3-conductor, 18 AWG black PVC covered power cord.
