Thanks to the construction principles of gasket, closing system and diffuser our LED fixtures ensure a high grade of protection (IP 65) against dust, contamination and water permeation. In accordance with their IP grade they can be widely used to illuminate spaces with dusty, humid environment. Diffuser with extremely high light efficiency through high light permeability, unique on the market, (up to 93% light transmissivity), an excellent light uniformity through well-balanced light dispersing (no shadows), elimination of the dazzling effect (no glaring), aesthetical appearance (no dots of the single LEDs), keeping the usual, well known features of the diffuser such as chemical and heat resistance, mechanical features, UV-stabilization etc. Housing is made of flame retardant glass-fibre reinforced polyester (on request suitable for 850°C glow wire test too), in light grey (RAL7035) colour. Glass-fibre reinforced polyester has very good temperature resistance, mechanical stability, furthermore it is a good electrical insulator, it resists the impacts of several chemicals and the impacts of weather conditions. Its stability of size and shape at changing temperatures is excellent. Parking places, warehouses, terminals, industrial refrigerators, shops, shops on processing, the furniture industry, car-care centers – most frequently used applications.
