FIELD OF APPLICATION: Thanks to the construction principles of the gasket, the closing system and the diffuser our LED fixtures ensure a high grade of protection (IP65, IP66) against dust, contamination and water permeation even at extremely low ambient temperature. In accordance with their IP grade they can be widely used to illumi- nate spaces with dusty, humid environment down to Ta -30°C. TECHNICAL DESCRIPTION AND BENEFITS: n Housing: It is made of flame retardant glass fibre reinforced polyester (on request suitable for 850°C glow wire test, too), in light grey (RAL 7035) colour. The glass fibre reinforced polyester has a very good temperature resistance and mechanical stability. Furthermore, it is a good electrical insulator resisting the impacts of several chemicals and weather conditions. Its stability of size and shape at changing temperatures is excellent. n Diffuser: Available in PC - injection moulded Polycarbonate . Main advantages: high mechanical strength and high heat and shock resistance Our LED luminaires with opal diffuser offer you: - very good light efficiency through high light permeability, (up to 90% light transmissivity) - the usual, well-known features of the diffuser such as chemical and heat resistance, mechanical features, UV stabilization etc. n In order to ensure maximum temperature, chemical and weather resistance even under tough conditions, the gasket between the diffuser and housing is made of silicone foam with enhanced durability. n Fixing of the diffuser to the body: with highly resistant stainless steel clips (standard or tamper-proof version).
