Quick Summary

MLLAW4-UNV1-P-M2 is a high-efficiency LED light fixture designed for hazardous-location illumination in industrial facilities. Engineers often struggle with reliable performance in extreme environments, frequent maintenance cycles, and complex regulatory reporting. The unit carries IP66 protection, NEC/CEC compliance for Class I, II, III locations, and a NEMA 4X enclosure to defend against washdowns and corrosion. With a 4 ft length, flush ceiling mount, warm white light, and 8000 lumens at 59 W, it delivers broad coverage and energy efficiency. This combination supports lower total cost of ownership through longer service intervals, reduced energy use, and simpler regulatory documentation across chemical processing, oil and gas, and heavy manufacturing facilities.

Hazardous-location compliance is built into the MLLAW4-UNV1-P-M2 with NEC/CEC certification and a Class I, II, III rating in a rugged NEMA 4X enclosure. This dedicated protection reduces ignition risk and simplifies regulatory audits, supporting safer operations across demanding sites. It is ideally suited for chemical processing plants, oil and gas facilities, and other environments where robust enclosure performance is non-negotiable. High lumen output of 8000 lumens at 59 watts provides broad, uniform illumination with a wide optical distribution. The combination lowers the number of fixtures required and minimizes shadowed areas, reducing maintenance cycles and energy spend. It’s particularly effective on large production floors, warehouses, and process areas where consistent visibility drives productivity. Efficiency of 135 lumens per watt translates to lower operating costs and cooler operation, supporting sustainability initiatives. The warm white light enhances color rendering for safety-critical tasks while maintaining comfortable work environments. This performance remains reliable under 50/60 Hz supply, ensuring stable brightness in most global facilities. Flex inputs of 120-277 Vac and 127/250 Vdc simplify integration with varied electrical distributions and site retrofits. The 4 ft fixture length and flush ceiling mounting streamline installation in low-clearance ceilings, cutting down commissioning time. The glass lens and copper-free aluminum housing resist washdowns and corrosion, extending service life in harsh environments. Copper-free aluminum with painted gray epoxy finish provides ruggedness in demanding locations and helps meet washdown and corrosion resistance requirements. The NEMA 4X protection, IP66 rating, and hazardous-location certifications support compliance across many industries, including marine, chemical, and refining operations.

FAQs

Yes. The MLLAW4-UNV1-P-M2 is designed for hazardous locations with NEC/CEC compliance and a Class I, II, III rating, including Division 1 suitability when used within its NEMA 4X enclosure. For retrofits, verify wiring compatibility with 120-277 Vac or 127/250 Vdc supplies and confirm ceiling clearance for a 4 ft flush-mount installation.
Key specs include 8000 lumens at 59 W, yielding about 135 lm/W, warm white color (approx. 3000–3500 K), 120-277 Vac and 127/250 Vdc voltage range, 50/60 Hz, and a 4X NEMA enclosure with IP66 protection. The fixture is designed for wide optical distribution with a 4 ft length and glass lens.
Yes. The combination of hazardous-location certifications, NEMA 4X enclosure, and IP66 protection make it appropriate for marine and offshore environments, where washdowns and corrosion resistance are critical. When used in conjunction with approved marine/industrial electrical practices, it supports reliable operation in harsh duty cycles.
The fixture carries NEC/CEC compliance for Class I, II, III locations, NEC hazardous ratings (Class III, II Division 1, Class I Division 2, and Zone 2), IP66/IP67 protection, and a NEMA 4X enclosure, enabling safe operation in many hazardous and washdown-prone environments.
The 8000-lumen, 59W LED design with long life and low maintenance reduces replacement cycles and energy costs compared with legacy lighting. Its rugged housing, IP66/IP67 protection, and washdown-ready finish further minimize downtime, delivering favorable total cost of ownership across chemical, oil & gas, and heavy manufacturing facilities.
