The Nemalux MR Series is a high-performance industrial-grade LED light fixture engineered for installation in marine, harsh, and hazardous locations. Its rugged yet lightweight construction, combined with versatile mounting options, makes it an ideal solution for a broad range of industrial applications. Designed for maximum durability and efficiency, the MR features a low-profile aluminum housing that simplifies installation in tight spaces, while its high-efficiency optical system delivers reliable illumination in demanding environments.
Engineered for environments where safety and performance are critical, the MR is certified for use in general, marine, and hazardous locations. It meets stringent safety standards, including UL 1598, UL 1598A, UL 8750, UL 844, and CSA equivalents, and carries ratings for Class I Division 2 Groups ABCD (T4), Class II Division 2 Groups FG (T4A), Class III, as well as Class I Zone 2 Group IIC and Zone 22. The fixture supports input voltage options of 120–277 VAC or 347 VAC and is built to withstand ambient temperatures ranging from -40°C to +55°C. With ingress protection ratings of IP66/67 and an available IP68 variant, the MR is sealed against dust and water intrusion—even under submersion.
The MR provides an output range of 3,000 to 6,000 lumens, making it suitable for mounting heights between eight and fourteen feet. Its secondary optics offer a wide range of beam distributions that allow for optimized lighting design with fewer fixtures—resulting in potential reductions of up to 50% in fixture count when compared to some conventional solutions. Advanced optical engineering ensures not only precise illumination but also improved visual comfort by minimizing glare through impact-resistant polycarbonate lenses.
Durability and long service life are key advantages of the MR. Its copper-free aluminum housing serves as a heat sink, while optimized fin spacing improves airflow and prevents the accumulation of debris, keeping internal components cool. A multi-layer powder coating offers added protection against chemicals and UV exposure, ensuring long-term resilience in corrosive environments. Select MR models are designed with full cut-off light control and can be used in Dark Sky-sensitive projects.
The fixture’s ease of installation and maintenance further enhances its appeal for industrial environments. The MR includes a built-in junction area with three 3/4” NPT entries, supporting through-wiring to minimize the need for external junction boxes. Components such as the LED module and driver are field-serviceable and do not require soldering, allowing end-users to extend the life of the fixture with in-field replacements and upgrades.
Designed for a wide range of deployment scenarios, the MR is used in walkways, platforms, conveyor belts, modular buildings, and service equipment. The UL1598A marine rating also makes it suitable for saltwater-rich coastal and offshore environments. Nemalux offers an IP68 version of the MR—model MR-EN—featuring a permanently sealed, optically clear encapsulant that enables full operation while submerged in up to 25 feet of water, making it ideal for maritime, tunnel, and infrastructure applications.
To simplify retrofits and reduce labor time, Nemalux provides a retrofit adapter for upgrading legacy Eaton Crouse Hinds light fixture hoods. This solution allows customers to reuse existing mounts while benefiting from the advanced features of the MR, dramatically reducing installation complexity and cost.
For hard-to-reach installations, Nemalux also supports integration with the Maxis™ lowering pole system—an industry-leading, high-safety luminaire support solution that eliminates the need for ladders, scaffolds, or lifts. This makes the MR even more practical for environments where safe and efficient maintenance access is essential.
The MR Series stands out as a robust, flexible, and efficient LED luminaire. With Nemalux's commitment to quality and engineering excellence, the MR is an ideal choice for both new construction and retrofit projects across a broad range of industries.
