The Louis Poulsen PH 4 1/2 - 4 Glass Pendant Lamp has three reflecting shades and thus the main part of the light is directed downwards. The shades consist of hand-blown opalised three-layered glass. They are glossy from the outside while the inner side is matt sand-blasted. This leads to a soft and diffuse distribution of light.
Please note that the Louis Poulsen PH 4 1/2 - 4 Glass Pendant Lamp has a long durability. It is perfectly suitable for being installed in-line. The PH 4 1/2 - 4 Glass Pendant Lamp went on sale in 1980.
