By Louis Poulsen.

PH 4½ - 3½ Glass Table 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 4½ - 3½ Glass Table provides soft illumination.

White opal handblown glass shades which have been sandblasted on the undersides for uniform light distribution. High luster chrome-plated brass top plate and socket compartment. Purple spun aluminum anti-glare ring. High luster chrome-plated steel stem. High luster chrome-plated brass base with on/off switch. 9 foot long black power cord with 120V plug.
