It is a flexible lighting system designed for modern work spaces. It is based on two different lighting elements interacting in space in smart compositions. Two different optical solutions are developed within the same profile. The first provides comfortable diffusing emission, illuminating non-operational spaces softly and efficiently. The second has a UGR controlled emission, ideal for work stations. Both are associated with non-prevalent indirect illumination. In linear configurations, maximum continuity of the individual modules is ensured, light runs uninterruptedly and both emission types can be combined. More traditional linear settings go hand in hand with more uneven compositions, unexpected open or closed geometries. The great new entry brought in Series Y is the possibility to develop on multiple levels to match different functional applications, also starting from a single power connection point.
