The Sonneman torus pendant is one of the brand's architectural collections. The precisely curved shape rotates around a central axis, creating a torus of reflected LED light that appears to float in the air with open ease. Suspended high or low in space, its delicate presence glows with warm reflected light.
Dimensions, mm: lampshade Ø 600 x 50
