Slim direct/indirect LED pendant luminaire for continuous row mounting with highly specular cell optics. Luminaire wattage: 78.8 W LED, electronic ballast with LED converter. LED service life is 50,000 hours with a reduction in luminous flux to 90% of the initial value. Luminaire luminous flux: 10,060 lm, luminaire luminous efficacy: 128 lm/W. Colour rendering Ra > 80, colour temperature 4000 K. Direct light control with highly efficient LED cell technology combined with primary optics for light point resolution. Cell modules are made of high-quality composite material, evenly vacuum-vapour-deposited with ultra-pure aluminium and protected with a SiO2 coating. Beam characteristics feature a high direct component for energy-saving lighting, with glare limitation in accordance with EN 12464-1:2011, L65 < 1500 cd/m² at 65° all round and UGR < 19 for VDU workstations. Indirect light control utilizes a continuous light guide profile for homogeneous light point resolution on the ceiling. The closed optical system provides contact protection for the LED modules against damage caused by electrostatic discharge. The powder-coated luminaire housing is made of angular extruded aluminium profile with a visible square cross-section, and features invisible screwed die-cast aluminium end caps coated in luminaire colour, which is silver anodised. The luminaire is wired halogen-free and includes one pre-assembled cable (1000 mm) with a cross cable. One feed module and one feed cable per strip light must be ordered separately. The suspension is infinitely height-adjustable and infinitely adjustable in the longitudinal direction. Dimensions: 2407 x 63 x 64 mm. Weight: 5.4 kg.
