771-EXTREME -30°C Industrial dust and waterproof luminaires with LED modules for ambient temperature down to Ta -30 °C With a new, opalised diffuser with unique light transmissivity! Specially developed for LED applications
YOUR MAIN BENEFITS: The shape of 771-Favourite adapted for extremely low (-30°C) ambient temperatures.
FIELD OF APPLICATION: Thanks to the construction principles of gasket, closing system and 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 illuminate 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 (RAL7035) colour. Glass fibre reinforced polyester has 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: 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. Available in PC - injection moulded Polycarbonate . Main advantages: high mechanical strength and high heat and shock resistance 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-based foam with enhanced durability. n Fixing of the diffuser to the body: with highly resistant stainless steel clips (standard or tamper-proof version).
n Gear tray (reflector): White powder coated steel sheet according to Zhaga standards or customised.
n Electrical components: in accordance with the requested specification suitable for LED technology. For more details please see technical data.
