This PH 5-4½ Charlottenborg lamp is designed by the designer Poul Henningsen. Poul Henningsen has reached worldwide fame after at first showing his PH selection on the Exposition Internationale des Arts Décoratifs in 1925- which is an Industriel Modern show in Paris. This reproduction of Poul Henningsen's original design are in the same style as Poul Henningsen's original PH assortment. The unique 4-shade design of the PH lamp is designed with the purpose of reducing
the reflection without sacrifacing the level of the created light.
