FEATURES & SPECIFICATIONS

INTENDED USE -- The RTLED combines digital LED lighting and controls technologies with patented highperformance 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. CONSTRUCTION -- Rugged, one-piece cold-rolled steel reflector assembly with embossed facets. Coated polyester powder-paint after fabrication. Rigid structure with ballast box and end plates. End plates include integral T-bar clips. Impact-modified acrylic prismatic refractor with polymer light-diffusing film. Luminaires may be mounted end-to-end and continuously wired. OPTICS -- 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. Regressed two-piece refractor system obscures and integrates individual LED images and uniformly washes the reflector cavity with light. Sloped end plates provide a smooth, luminous transition between fixture and ceiling while enhancing the perception of fixture depth. ELECTRICAL -- Long-life LEDs, coupled with high-efficiency drivers, provide superior quantity and quality of illumination for extended service life. RTLED is rated to deliver L80 performance for 50,000 hours. Standard nLight® embedded controls make each luminaire addressable - allowing it to digitally communicate with other nLight enabled controls such as dimmers, switches, occupancy sensors and photocontrols. Simply connect all the nLight enabled control devices and the RTLED luminaires using standard Cat-5 cabling. Unique plug-and-play convenience as devices and luminaires automatically discover each other and self-commission. Lumen Management: Unique lumen management system (option N80) provides onboard intelligence that actively manages the LED light source so that constant lumen output is maintained over the system life, preventing the energy waste created by the traditional practice of over-lighting. Bi-level dimming option allows system to be switched to 50% power for compliance with common energy codes while maintaining fixture appearance. LED AccuDrive TM driver delivers full-range dimming from 0-10V control signal. Ballast disconnect provided where required to comply with US and Canadian codes. INSTALLATION -- Drivers and internal components accessed via plenum. Driver tray may be removed from fixture during service. Suitable for damp location. Maintenance: LED boards include plug-in connectors for easy replacement or servicing.

Constant Lumen Management

Enabled by the embedded nLight control, the RTLED actively tracks its run-time and manages its light source such that constant lumen output is maintained over the system life. Referred to as lumen management, theis feature eliminates the energy waste created by the traditional practice of over-lighting.
