Alba is an award-winning wall lamp that provides a diffuse light, optionally adjustable by rotating the disk, from which the shape has been conceived. A lamp that invites users to interact with it and discover the hidden affordance or action possibility to operate it. Alba is also the Catalan word for the twilight in the morning, when the sun is not directly visible because it is below the horizon, and the sunlight, scattering in the upper atmosphere, illuminates the sky with a charming soft light.
