The W2 wall lamp is part of the Lederam collection from Catellani Smith, created by Enzo Catellani. The design is pared down yet decorative and comprises two components, a simple linear metal arm and a circular disk in aluminum. Light is reflected off the disk, creating a soft, indirect diffusion of light in the room. The lightbulbs consist of integrated LED lights that are dimmable. Lederam W2 is the model of the wall lamp with two fixtures. It is available in several color combinations of powder-coated metal in black or white in contrast to gold leaf, copper, or silver. Like all Catellani Smith lighting, this collection is handmade in Italy, just outside Bergamo on the banks of the Serio River.
