A single ribbon of aluminum turned into a spiral, lit along its inner edge. The light follows the curve from the base to the tip, so the shape itself is what lights the desk. Key Features The form is the light. The lit edge runs the whole length of the spiral, which gives a line of light rather than a pool. Tone and brightness on the cord. One button moves it between warm, neutral and white, and takes the level up or down. Runs from a USB port. Plug it into a laptop, a wall adapter or a power bank. A small footprint. The coil sits within its own base, so it takes up little of a working desk.

It suits a modern room where the lamp is meant to be looked at as well as worked by.
