About the Symmetric Linear Collection
HARMONY AND GEOMETRY OF SPACES. Symmetrical linear profiles are designed to ensure uniform distribution of light, ideal for enhancing the geometry and surfaces of an environment. These luminaires are perfect for creating balanced and harmonious atmospheres, highlighting the volumes and recesses of walls while playing with light and shadows to enrich and amplify the perception of space.
REDEFINING SPACES. Extraordinarily slim solutions, such as Cometa Q4 and Cometa Q8, combine high performance with excellent quality diffused light. The use of these symmetrical linear profiles makes it possible to create light installations capable of infusing rhythm and character into spaces, making the design of light the true protagonist of the environment.
