The RTLR Relight assembly combines digital LED lighting and controls technology capabilities with patented high-performance optical design to offer the most advanced retrofit solution available 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. The RTLR is suitable for quick, simple retrofit into nearly any existing deep-cell parabolic or lensed troffer fluorescent fixtures (see dimensional requirements).
The relight assembly consists of four basic component parts that easily install into the host fixture.
End brackets are heavy-gauge powder-painted steel and are attached securely to the host fixture with included hardware. These brackets provide all of the support and attachment points for the light engine and trim assemblies. End bracket flanges have black finish to match reveals of most deep-cell parabolics.
The light engine serves as the reflector system and heat-sink and is finished in high-reflectance white powder paint. To reduce time and labor for installation, all electrical components are shipped installed and prewired on the light engine for simple electrical connection via the installed driver quick disconnect. A unitized trim assembly provides reflector and refractors for volumetric performance and architectural aesthetics. Molded and recyclable PETE (polyethylene) reflector is firmly attached to the universal bracket via hinge and latch assembly. Included in this assembly are two prismatic acrylic refractors with light-diffusing finish for even illumination and LED obscuration.
A steel splice box accessory is included with the kit for use when required by non-standard retrofit wiring conditions.
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 refractor system obscures and integrates individual LED images and uniformly washes the reflector cavity with light. Sloped end panels provide a smooth, luminous transition between fixture and ceiling while enhancing the perception of fixture depth.
Long-life LEDs, coupled with high-efficiency drivers, provide superior quantity and quality of illumination for extended service life. RTLR is rated to deliver L80 performance for 50,000 hours.
eldoLED driver options deliver choice of dimming range and choices for control, while assuring flicker-free, low-current inrush, 89% efficiency and low EMI. 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 RTLR 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.
Driver disconnect provided where required to comply with US and Canadian codes.
Trim hinges from either side and latches securely with cam-action latches. LED access by hinging trim down to 90º, providing tool-less access to light engine. For tool-less access to driver, twist 1/4-turn latches and hinge light engine down. LED boards include plug-in connectors for easy replacement or servicing.
Suitable for use in host fixtures rated for static or many air-handling functions. (Consult factory for details on air-handling compatibility).
