Betwo came about from the idea of using an innovative and spatial relationship to stage Opti Diamond technology, capable of changing the perception of space by animating it. Direct as well as direct/indirect emission, with general lighting versions, u UGR<19 and luminous fluxes from 1300lm up to 6600lm. It was decided to add an element to the simple, circular shape capable of capturing and narrating light. The two elements can also be combined with different finishes to create decorative details that fit into and characterize the setting.
