The PH3/2 Glass Table Lamp - Aged Brass Limited Edition from Louis Poulsen showcases a heritage look based on an iconic design. It is based on the principle of the reflective three-shade system, developed in the 1920s by Poul Henningsen. The top shade is made from brass to direct the light downward, while the two shades below are mouth-blown glass, which diffuses the light, creating "an island of light on the table," as Henningsen once put it. The three shades are sandblasted on their undersides, aiding in the soft distribution of light.
