Inspired by old tube amplifiers from the 1960s, designer Simon Legald shapes a sophisticated wall lamp from a mix of luxe elements. Amp finds a glass shade slipped over a marble fitting, with a curved arm and wall plate in powder-coated metal. A decorative LED bulb emits a stunning dimmable glow filtered through the smoked or golden glass. Normann Copenhagen's light can be installed as a hardwired fixture or as a plug-in with the included power cord.
