Rectangular and square anodized aluminum body IP20 LED ceiling luminaire with TR95% optical white matt aluminum sight blocking light distribution and glare control angled cubic louver without underlay diffusing elements. Suitable for recessing in T24 600 x 600 and 625 x 625 mm grid ceilings as well as plaster & clip-in system ceilings and pendant, surface and rail track mounting with accessories to be ordered separately. Precise light distribution control over 42.0° ensures low glare (UGR<15) visual comfort and photometric performance guaranteeing average +84,9% (TM5 utilization factors table average) of generated light to be conveyed directly to working plane. Eco-friendly construction enables easy disassembly & re-cycling of components and easy replacement of lamp unit as required by ecodesign. Energy efficacy level ranging between 145 to 156 lm/w coupled with high UF values enable driving luminaires at low current which in turn provides low LED junction temperature promising luminaire efficient service life / L80B10 (t_q 25°C) >50.000h. and chromatic stability / color consistency over the entire luminaire life. Luminaire body of 10 µm anodized aluminum. Further color anodized and RAL colors painted finishes on request. Control gear unit is open-circuit proof and protected against faulty connection, short circuit, overload and over-temperature. The control gear and PCB lamp unit are replaceable. Output ripple of the control gear unit <5% – PSTLM ≤1 – SVM ≤0.4 for effective control of the LED system and for flicker-free light.  The luminaire complies with fundamental requirements of applicable EU regulations and product safety legislation and bears the CE symbol. The luminaire is part of a range of recessed, surface-mounted and suspended luminaires with a harmonized appearance. Project-specific versions with varying luminaire characteristics are possible on request.
