Lithonia Lighting MSL LED Low Bay
Features & Specifications
Intended Use: The MS Series LED is a linear solution ideal for open-ceiling or suspended applications with mounting heights from 14 to 20 feet. It can be mounted in a continuous row or as a stand-alone unit. Its full-body construction and multiple mounting options adapt to a wide variety of suspended and open-ceiling applications.
Construction: The full-body housing and optical assembly is precision-formed using 20-gauge steel. The optical assembly ships factory-installed into the housing and utilizes aircraft cable tethers to support the optical assembly during wiring. The lensing integrates seamlessly into the optical housing to provide a sealed chamber to mitigate dust and insect collection. A convenient access plate is located on the back of the channel for access to the wiring compartment.
Finish: High-gloss, baked white enamel finish. Five-stage iron phosphate pretreatment ensures superior paint adhesion and rust resistance.
Optics: Optical design distributes light in the 0-60 degree zone, providing better utilization of light on task. Each linear bar is outfitted with premium, anodized MIRO 5® aluminum to ensure the highest lumens per watt can be achieved. A diffuse acrylic lens eliminates pixels to minimize glare and improve uniformity.
Electrical: The MSL luminaire has 94% lumen maintenance at 60,000 hours with an expected life of greater than 100,000 hours. The MSL ships standard with a thermally protected dimming driver that dims down to 5% using 0-10V controls. Optional EldoLED driver allows for flicker-free dimming down to 1%. LEDs are driven to provide optimal lumens per watt and less heat to extend component life. The driver and optical housing are connected with a mating plug for easy removal or future upgrade. Optional PLR through-wire harnesses are available for continuous-row installations.
Installation: A variety of mounting arrangements are available including tong hangers, aircraft cables, and stems. Suitable for mounting in continuous-row or individual mounting. End caps include knockouts for through wiring and fixture attachment in row-mounting applications.
Listings: UL and cUL listed to US and Canadian standards. For use in damp and dry locations with ambient temperatures ranging from -20°C (-4°F) to 30°C (86°F).
Buy American Act: Product with the BAA option is assembled in the USA and meets the Buy America(n) government procurement requirements under FAR, DFARS and DOT regulations. Refer to www.acuitybrands.com/buy-american for additional information.
