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, and creating soft shadows while using incandescent bulbs as a light source. The PH 4½-4 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.

The PH 4½-4 Glass Pendant consists of an approximately 45 cm top shade, but uses lower shades from the 4/4 model. These hybrid models were introduced due to the desire to hang the pendants at lower heights. The system was also used for wall, table and floor lamps. The 4½-4 Pendant in its current form was introduced in 1980.
