The fixture provides uniform, general and diffuse illumination. The opening at the bottom of the glass produces downwards directed light. The quality of the glass ensures that the fixture is evenly lit.

In 2016 Louis Poulsen has relaunched the original Radiohus Pendant from the 1940s under the name of VL45 Radiohus Pendant. The Radiohus Pendant was originally created for the Radiohuset building on Frederiksberg in Copenhagen, which was designed by the architect Vilhelm Lauritzen (1894-1984)– one of the leading proponents of modernism and functionalism. Vilhelm Lauritzen also designed all the lights for the Radiohuset building in partnership with Louis Poulsen. The Radiohus Pendant has since become a cherished design icon that is in great demand at antique markets and auctions.

The fixture features the original design, updated to accommodate modern advances in light technology and energy efficiency. The Radiohus Pendant consists of three layers of mouth-blown glass. The innermost and outermost layers are made of transparent polished glass, while white glass is used for the intermediate layer.

The VL45 Radiohus pendant comes in 2 sizes: Ø 25 cm and Ø 37 cm.
