The RTLX series surface mount combines digital LED lighting and controls technologies with patented high-performance optical design to offer the most advanced luminaire for general-ambient lighting applications. High-efficacy light engine delivers long life and excellent color, ensuring a superior quality lighting installation that is highly efficient and sustainable. Rugged, steel reflector with embossed facets. Painted after fabrication. Housing formed from cold-rolled steel. Plasma seam welded corners provide a clean finish and eliminate light leaks. Housing formed from cold-rolled steel. Housing is painted after fabrication for superior finish. Smooth hemmed sides and smooth inward-formed end flanges for easy handling. Volumetric illumination is delivered by creating an optimal mix of light to walls, partitions, vertical and horizontal work surfaces rendering the interior space, objects and occupants in a more balanced, complementary luminous environment. Light distribution is carefully controlled at high angles, providing just enough luminous flux to create the volumetric effect. Linear faceted reflector cavity softens and distributes light into the space while minimizing luminous contrast between the fixture and ceiling. Sloped end plates provide a smooth, luminous transition between fixture and ceiling while enhancing the perception of fixture depth.
