U3 links a pure and simple design with high performance and comfort. This series of recessed luminaires uses Shielded Lens technology, which screens off the LED light and prevents glare. U3 is therefore suitable for diverse applications such as in offices, classrooms, public spaces, etc. The lenses are countersunk and screened off by the shielding units so that the light source is barely visible at eye level, resulting in a highly uniform, quiet image. U3 is available with different light distributions and several luminous fluxes.
