COSMO LENSES are Low Profile Lenses for COB LEDs with LES from 6mm to 22mm Ø. They are available in 3 sizes - 50/70/90 mm Ø – and meet MR16, PAR30, AR111 standards. The typical TIR-Fresnel design reduces the lens height, resulting in a unique "Low Profile" design. Each size delivers three beam angles: Narrow, Medium, Wide. Both viewing and field beam angles depend on the LES of the COB LED you will use. The FROSTED FINISH of the NARROW BEAM VERSIONs makes the light flux smooth and diffused. They are perfect for lighting in different environments, in commercial and residential living spaces. A holder, available in clear and black colour, enables easy mounting on the heatsink. However, they can also be mounted alone by leveraging the mechanical parts of the lighting fixture.
