LED efficiency and high output translate to lower energy costs and extended service life, helping facilities meet sustainability targets while keeping critical areas well lit. Feature → Business Impact → Application: 8000 lumens at 59W and 135 lm/W delivers bright, task-focused illumination, reducing electricity consumption and improving operator visibility in hazardous zones such as chemical processing lines and refineries. This supports compliance with NEC/CEC in Class I/II/III locations and minimizes re-lamping downtime across plant floors. Feature → Application alignment: narrow optical distribution with a diffused polycarbonate lens concentrates light along work cells and aisles, cutting glare and enhancing safety in machine shops and assembly lines. Feature → Compatibility: 347–480 VAC, 50/60 Hz operation enables seamless integration with existing power distributions, lowering retrofit costs and simplifying procurement for industrial facilities. Feature → Durability: copper-free aluminum and painted white epoxy finish resist corrosion and harsh environments, ensuring long service life in wet or dusty areas. Feature → Protection: IP66/IP67 and NEMA 4X ruggedness protect sensitive electrical components from dust, water, and impacts, enabling outdoor or hazardous-location installations with reduced maintenance. Feature → Compliance and installation: flush ceiling mounting simplifies retrofits and new-builds, delivering faster installs and predictable lighting layouts for code-compliant hazardous-area lighting.

FAQs

For hazardous locations, install the MLLAW4N-UNV34-S903D-WH-M2 with flush ceiling mounting to minimize clearance issues and maximize protection. Ensure 347-480 VAC supply is present and confirm Class I/II/III and Zone classifications match local codes. Use correct ingress protection (IP66/IP67) and verify that the 3/4" entry conduits are properly sealed to maintain hazardous-area integrity.
This LED fixture delivers 8000 lumens at 59 watts, achieving approximately 135 lumens per watt. It operates at 347–480 VAC, 50/60 Hz, and maintains a power factor greater than 0.98. These specs support energy savings, reduced cooling loads, and reliable performance in industrial power systems typically found in hazardous locations.
Yes. The fixture is designed for Hazardous/Classified Locations, including Class I Division 1 and Zone 2 configurations, with additional Class II and Class III coverage. This ensures compliance with NEC/CEC in diverse hazardous environments, enabling safe operation around flammable atmospheres and electrical equipment.
The luminaire carries NEMA 4X protection and IP66/IP67 ingress ratings, suitable for dusty, wet, and harsh industrial settings. It also aligns with NEC/CEC standards, providing hazardous-location approvals. These certifications support regulatory compliance, reduce risk during audits, and enable outdoor or washdown-ready installations.
Expect reduced maintenance due to long LED life and high-quality materials (copper-free aluminum, epoxy finish) that resist corrosion. The improved efficiency (8000 lm at 59W) lowers energy costs and cooling requirements, delivering a favorable ROI in plants with frequent staff-led maintenance and strict lighting uptime requirements in hazardous zones.
