The functionality of Optunia lies in the possibility of rotating the two discs that make up the nearly 360-degree head, opening up an extraordinary number of lighting combinations.  The lower disc rotates on one axis, while the upper disk simultaneously rotates on a second axis, perpendicular to the first. This double movement gives Optunia to the advantages of both direct and indirect light emission, which exploits the surface of the wall or ceiling to produce a soft light. Opuntia ficus indica, which the lamp takes its name. A family of exceptional technical sophistication.
