High lumen output with 8000 lumens and 135 lm/W provides bright, uniform illumination across large workspaces, enabling safer, faster task execution and reducing the need for multiple fixtures. This translates to tangible energy savings per installation and improved visibility for critical operations such as mixing, grading, and inspection in chemical plants and mining sites. Application: long runs of lighting in process areas, storage floors, and maintenance bays where clear visibility accelerates work and lowers operating costs. Rugged IP66/IP67 rated enclosure with NEMA 4X protection guards against dust, water jets, and corrosive exposure, delivering sustained performance in harsh environments. This reduces maintenance cycles and extends service life in offshore platforms, refineries, and waste-water facilities. Application: hazardous locations with harsh washdown or spray zones. Integral emergency battery back-up maintains essential lighting during power outages, supporting safe egress and compliance with life-safety requirements. Application: emergency lighting in facilities where shutdowns pose safety risks. Copper-free aluminum construction with epoxy finish and a polycarbonate lens provides corrosion resistance and impact protection, lowering replacement costs over the fixture’s life. Application: outdoor or damp industrial settings, chemical processing, and grain-handling facilities. Universal voltage compatibility 120-277 Vac and 127/250 Vdc simplifies stocking and integration with existing electrical systems, reducing logistic complexity. Application: retrofit projects and new installations across multi-voltage sites. Flush ceiling mounting with a 39 in long housing and 3/4 in entry sizes ensures a clean, space-efficient install with flexible wiring options. Application: ceiling runs in constrained spaces and retrofit programs where appearance and reliability matter.

FAQs
The fixture supports universal voltage operation from 120 to 277 VAC and 127/250 VDC, enabling straightforward integration with common industrial power distribution. This compatibility reduces the need for multiple variants and simplifies procurement. For retrofits, consider ensuring the control gear is rated for the same voltage band and verify wiring routes accommodate the 3/4 inch entry size.
The MLLA4-UNV1-S903-EM1-P-M2 carries NEC/CEC compliance for hazardous locations, Class I Division 2, Zone 2, Class II Division 1, and Class III, along with a NEMA 4X enclosure rating and IP66/IP67 protection. These certifications support compliance with global and regional codes, enabling installation in chemical plants, mining, offshore facilities, and other classified environments.
This LED fixture delivers 8000 lumens at approximately 135 lumens per watt, consuming 59 watts. The high efficacy reduces energy consumption compared with traditional lighting while maintaining strong visibility. For facilities with long operating hours, this translates to meaningful annual energy savings and lower total cost of ownership.
The unit includes an integral emergency battery back-up, ensuring lighting remains available during power interruptions and meeting safety and egress requirements. This is critical in hazardous environments where outages can pose significant safety risks and downtime costs, helping to maintain visibility during critical transitions or evacuations.
With a 39 in length, flush ceiling mounting, and 3/4 in entry sizes, installation is clean and adaptable to existing runs, reducing downtime during retrofits and new installs. The copper-free aluminum chassis and epoxy finish minimize corrosion-related maintenance, while wide optical distribution improves coverage, decreasing the number of fixtures required for the same area.
