The Coil Table Lamp is the result of Castor Design's ongoing attempts to re-contextualize materials. It is constructed of a single piece of machined aluminum with a copper base and custom spring, and uses Apple’s first-generation MagSafe laptop adapter as a power supply. Users recycle their own pre-existing power supply, which provides ecological and economical benefits.
The lamp incorporates a strip of LED bulbs to emit a warm directional light that is diffused by an acrylic lens. The power source is attached magnetically to the back of the lamp's adjustable head. Castor’s experiments with technologies that are approaching obsolescence resulted in the first product to use the MagSafe adapters as anything other than a laptop charger.
