Called Chipperfield w102, the design consists of a cylindrical lamp head and base joined by an L-shaped arm.
The lamp features LEDs that can be dimmed, and rotates at the base and head joints.

Wästberg and David Chipperfield in collaboration Press Release
At the Stockholm Furniture Fair 2010, Wästberg will launch a lighting fixture developed in collaboration with British architect David Chipperfield.
The product references an archetypal personal desk lamp for home or office use, and seeks to offer a fresh interpretation of the familiar on a domestic scale. The lamp is predominantly made from brass - a material commonly associated with lights, though not so widely used today - with details in rubber. The intention was to create a simple form with a clear distinction between a base, a single arm and a lamp head. The lamp has no visible joints and minimal directional movement, without compromising its function.
Launched in 2008, Wästberg’s lamps are now sold globally and have been honoured with more than 20 awards for design excellence, including 6 Good Design Awards, 3 red dot awards, Design Award of the Federal Republic of Germany and Elle Interiör Design Prize. Wästberg is based in Helsingborg, Skåne, the southernmost part of Sweden.
