Coil Lamp is the distillation of a lamp to its most essential elements: cord, socket, and bulb. The power cord appears to create the lamp's iconic shape by itself, elevating a humble extension cord from the toolbox to the realm of domestic design. Learn more here.

Originally designed by Manual founder Craighton Berman in 2009, Coil Lamp became part of the per­manent collection of the Art Institute of Chicago in 2012.

Coil Lamp is now in ''open source'' edition—available for download as a digital cutting file and a set of instructions. The user is encouraged to have their parts laser cut from cardboard, yielding a less expensive product, lowering environmental impact by avoiding plastics, and reinforcing the ''temporary'' nature of design: If the Coil Lamp is no longer wanted, the card­board can be recycled and the cord reused.

Coil Lamp is made via two laser-cut profiles that brace against each other to create a framework for wrapping the cord. The profile files can be uploaded to a laser cutting service, and for around $35 in materials, an extension cord, and 30 minutes of your time you too can create your own.
