Story
A glass table lamp from 1928
The PH 3½-2½ Glass Table lamp was designed in 1928 as one of Poul Henningsen's projects in developing the three-shade system.
Shape and light
The shades follow a logarithmic spiral to make the most of the light source, and the lamp was designed to be glare-free. Underneath, the glass is sandblasted matte while the top stays glossy, giving soft and uniform light distribution.
