Its functionality 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. Design - Claesson Koivisto Rune , 2017. 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. Finish in white, dark bronze or glossy black.
