PH 3½ - 2½ Floor 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. The PH 3½ - 2½ Floor is ideal for applications where general up lighting of a room is necessary.

White opal handblown glass shades which have been sandblasted on the undersides for uniform light distribution. High-luster chrome-plated brass base and top plate. High luster chrome-plated steel stem. 12 foot long black power cord with in-line on/off foot switch and 120V plug.
