Weighing in at 12 kg (26 lbs.), Unit-Berlin’s hefty Concrete Lamp was originally handmade from cast-in-place concrete for a Berlin restaurant. A limited number of lamps are now available to the public. The design celebrates the relationship between concrete and reinforcing steel: A steel ring supports the 25cm-diameter shell in a tabletop fixture, while a customized rebar supports the pendant version. The lamp can be fixed at three different angles in the pendant.
