ACUITY/LITHONIA 212L9N LED Troffer LED 40 W, 120 - 277 V, 4 ft L x 610 mm W x 111 mm H Direct, Symmetric, Dimmable

Intended use: The VT Volumetric Troffer combines the aesthetics and high performance with intelligent LED engines for applications - offices, schools, retail locations and hospitals. High-efficacy light engine delivers long life and excellent color, ensuring a superior quality lighting installation that is highly efficient and sustainable. Featured nLight controls system provides design flexibility and ease of installation and optimum energy savings. Construction: Rugged, one-piece cold-rolled steel coated polyester, painted after fabrication with embossed facets. Impact-modified, single clear acrylic diffuser provides excellent shielding and wide distribution. End plates include integral T-bar clips. Fixture may be mounted and wired in continuous rows. Total fixture height is only 4-3/8. Optics: Volumetric illumination is achieved 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. 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. Advanced optical film provides superior LED concealment and even illumination across the diffuser. Electrical: Long-life LEDs, coupled with high-efficiency drivers, provide superior quantity and quality of illumination for extended service life. VTLED 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 VTLED 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 ™ driver delivers full-range dimming from 0-10V control signal. Driver disconnect provided where required to comply with US and Canadian codes. Installation: Unique grid interfacing arrangement provides mounting into standard 1 and 9/16 tee bar or screw slot grids. 9/16 allows fixture trim to hang level with architectural ceiling tiles. Drywall ceiling adaptors available. Suitable for damp location. Listings: CSA Certified to meet U.S. and Canadian standards. Patents pending.
