Lithonia Lighting MS Series LED Low Bay Luminaire

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 is available as a complete luminaire, utilizing the time-tested MS housing. The traditional fixture design offers time-saving installation options, making it a favorite for contractors. 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.

Environmental Considerations: Certain chemicals in end-user locations can release airborne contaminants affecting fixture components. Refer to the environmental compatibility chart in the Product Selection Guide or on the company website for chemical interactions. Consult an authorized factory representative for additional information. Certain airborne contaminants can diminish the integrity of acrylic and/or polycarbonate.

Construction: The full-body housing and optical assembly are precision-formed using 20-gauge steel. The optical assembly ships factory-installed into the housing and utilizes aircraft cable tethers to support it during wiring. The lensing integrates seamlessly into the optical housing, creating 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. A five-stage iron phosphate pretreatment ensures superior paint adhesion and rust resistance.

Optics: The optical design distributes light primarily in the 0-60 degree zone for better utilization of light on task. Each linear bar is outfitted with premium, anodized MIRO 5® aluminum to ensure the highest lumens per watt. A diffuse acrylic lens eliminates pixels to minimize glare and improve uniformity.

Electrical: The MSL luminaire offers 94% lumen maintenance at 60,000 hours with an expected life greater than 100,000 hours. It ships standard with a thermally protected dimming driver that dims down to 5% using 0-10V controls. An optional EldoLED driver allows for flicker-free dimming down to 1%. LEDs are driven for optimal lumens per watt and reduced 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. The fixtures are suitable for 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. Suitable for use in damp and dry locations with ambient temperatures ranging from -20°C (-4°F) to 30°C (86°F).

Government Procurement: BAA (Buy American Act) and BABA (Build America, Buy America) options are available, qualifying the product as a domestic end product and manufactured in the United States. Refer to www.acuitybrands.com/buy-american for additional information.
