RTLED

RT Series Volumetric LED Luminaires

The RTL 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.

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. 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

Longlife LEDs, coupled with high efficiency drivers, provide superior quantity and quality of illumination for extended service life. RTL is rated to deliver L90 performance for 60,000 hours.

Optional integrated nLight®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 RTL 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.

Step level dimming option allows system to be switched to 50% power for compliance with common energy codes while maintaining fixture appearance.

eldoLED driver options deliver choice of dimming range, and choice of control, while assuring flicker-free, low current inrush, 89% efficiency and low EMI.

Driver 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. Maintenance: LED boards include plug-in connectors for easy replacement or servicing.
