Duo 4874 LED ceiling light made of wood and aluminium The Duo 4874 ceiling light has the shape of a bowl and consists of two layers: Inside is a layer of oak wood and the outside is made of matt aluminium. The light's warm light is achieved using the latest LED technology, which is embedded in the shell. A diffuser made of polycarbonate dims the light and also reflects it off the wood, creating a cosy ambience. Duo 4874 was created by the designer duo Ramos & Bassols for the manufacturer Vibia. They deliberately chose wood as the material, as it is a natural, high-quality material and radiates a warmth that forms an interesting contrast to the cool aluminium.
