The shades are made of hand-blown opal three-layer glass, which is glossy on top and sandblasted matte on the underside, giving a soft and uniform light distribution.

Poul Henningsen designed the three-shade system during 1925/1926. The first lights using the system were designed for an exhibition in Paris. His work with Louis Poulsen continued until his death in 1967. Throughout his life, PH sought to create glare-free lighting; aiming to direct light where it was most needed. The PH 4.5-4 Glass Pendant is a member of the three-shade family and is one of 19 versions available today. Approximately one thousand models have been produced over the years and consisted of table, floor and wall lamps, as well as a number of chandeliers, which were popular in the 30s for lighting private homes with high ceilings.
