A single polyvalent fixture for use either as a projector or a louvre, combining design, sturdiness and superlative technical lighting features. The dual possibility of symmetrical and asymmetrical light diffusion is embodied in the same product and is achieved thanks to a louvre with divisible modules. A single fixture to achieve total coverage in outdoor lighting, solving the most varied technical lighting problems thanks to an innovative optical project based on efficiency and glare control. The small dimensions of the housing contrast with the depth of the beam of light which has no limits of use.
