OPTIMA (USO) LED luminaires are to be suspended by cord of diameter from 4 to 10 mm. The luminaires housing is made of aluminium, structural elements are of stainless steel. These luminaires are resistant to environmental effects. Thought-out heat dissipation guarantees continuous operation according to claimed specifications and without failures during the lifetime of a luminaire. Wide range of LEDIL optics (Finland) makes OPTIMA (USO) luminaires be adopted for illumination of various objects such as squares and streets, public transport stops, pedestrians, tram ways. High ingress protection rating IP 67.



  • High efficacy, over 110 lm/ W;
