A collaboration with Foster + Partners, Artemide’s Ixa floor lamp interprets the “elegant balance” of Alexander Calder’s sculptures through a system of counterweights and pivot points that allow for rotation and inclination. Further, the spherical head welcomes interaction: Attached to its extension bar with a magnet, it can be rotated freely 360 degrees, directing light where it’s needed. Also available in table and wall versions, Ixa comes in Charcoal, Crane (yellow), Ink (blue) and Slip (light grey).
