PH 2/1 pendant  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 brass base, stem and top plate. 9 foot long black power cord with in-line on/off switch and 120V plug.
