Poul Henningsen's shade sizes

Shade size gives each PH light its model numbers. For the PH 4½-3½ Glass Table the top shade measures approximately 45 cm, and the lower shades come from the 3½ model. The current form of this table lamp was introduced in 1990.

Glass that diffuses

In the reflective three-shade system most of the light goes down. Each shade is glossy above and matte sandblasted below, so the light comes out soft and diffused.
