The PH 3½-2½ table lamp from Louis Poulsen is a classic reading lamp with a timeless design by Poul Henningsen. The reflections from the three shades spread over a logarithmic spiral and direct the majority of the light downward. The shades are made of opal glass which gives a soft and diffuse light. The table lamp is part of the three-screen family that Poul Henningsen designed in a collaboration with Louis Poulsen between 1925-1926. A light source is not included.
