Lithonia Lighting 122731 LED Relighting for Lensed Troffers VTLRT LED
The 2VTL4RT and 2VTL2RT LED Relight assembly is the ideal solution for renovating existing fluorescent lensed troffer systems, delivering improved quality of light and refreshing the space. VTLRT volumetric lighting eliminates the Òcave effectÓ by delivering the ideal amount of light to walls, work surfaces, and people. The 2VTL4RT and 2VTL2RT Relight assembly is recommended for offices, schools, hospitals, and other general lighting applications where existing 2x4 or 2x2 lensed troffer fluorescent fixtures are currently in use Construction Universal end brackets are constructed of 20-gauge powder-painted steel and are secured to the host fixture with provided tek screws. End brackets are painted white to match existing lensed troffer doorframe surround. White molded trim strips are included with kit to complete the installation and cover hinge gaps left by removal of the lensed doorframe (if required). The LED light engine is 20-gauge powder painted steel. A steel wiring connection cover is provided for use if required. The doorframe and reflector assembly is vaulted cold-rolled steel with embossed facets and is painted after fabrication. Impact-modified, single clear acrylic diffuser provides excellent shielding and wide distribution. Optics Volumetric illumination is delivered by creating an optimal mix of light to walls, partitions, vertical and horizontal work surfaces Ñ rendering the interior space, objects and occupants in a more balanced, complementary luminous environment. 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. Electrical Long-life LEDs, coupled with high-efficiency drivers, provide superior quantity and quality of illumination for extended service life. 2VTL4RT is rated to deliver L80 performance for 50,000 hours. LED AccuDrive ª driver delivers full-range dimming from 0-10V control signal. Installation After existing fluorescent components are removed from housing, universal end brackets are fastened in place with tek screws. The LED light engine assembly mounts to the end brackets and hangs securely. The light engine then swings up into position and is secured in place with a captive screw at each end. The doorframe is then inserted via a sliding hinge into the end bracket and secured in the closed position with a rotating cam latch. Light engine may be removed from fixture during service. LED boards include plug-in connectors for easy replacement or servicing. Installation of Relight assembly does not significantly reduce air-handling functions. Suitable for damp location and air-handling installations.
