Product Description
Elegant and classic. The VL Ring Crown Wall Sconce by Louis Poulsen comes from a design Danish architect Vilhelm Lauritzen composed in the 1940s for the Danish Broadcasting Corporation headquarters. Designed as an alternative to the classical spherical pendant, this piece was created to be attractive, glare-free, and practical. A single, glossy white, triple-layered, mouth-blown opal glass piece has a shapely and organic form that complements the curved metal arm supporting it, adding a sophisticated touch and layer of light to living spaces.
