With 8000 lumens at 59W and an impressive 135 lm/W, this fixture delivers bright, consistent illumination while slashing energy use in open areas, process bays, and high-ceiling spaces. The result is lower operating costs and fewer replacements due to premature failures. Universal voltage 120-277 VAC and 127/250 VDC support global deployments, simplifying stocking and electrical design across sites. Engineers can specify a single luminaire for multi-region projects, speeding procurement and reducing installation risk. IP66 and IP67 ingress protection, along with NEMA 4X, protect against water, dust, and corrosive atmospheres in hazardous locations, enabling safe operation in chemical plants, offshore facilities, and mining environments with fewer enclosure changes. Copper-free aluminum housing with a gray epoxy finish resists corrosion in humid and coastal environments, extending service life in challenging facilities. Polycarbonate lens and a narrow optical distribution minimize glare and optimize foreground lighting for operator comfort and safety during critical tasks. Flush-ceiling mounting and a 4 ft form factor simplify installation and retrofit, reducing labor time and disruption during plant turnarounds.

FAQs

Install the luminaire using a flush ceiling mount with the 4 ft form factor. Use the 3/4 inch entry for conduit and follow local codes for hazardous locations. Ensure proper sealing with gaskets and weatherproofing, and verify the unit weight of 19.5 lb during handling and mounting. Wiring should comply with NEC/CEC requirements for Class I/II/III environments.
The MLLAW4N-UNV1-S903-P-M2 is certified for Hazardous/Classified Locations, including Class I Division 2, Class II Division 1, Class III and Zone 2, with IP66/IP67 protection and a NEMA 4X rating. These certifications support NEC/CEC compliance and safe operation in demanding environments such as chemical plants and offshore facilities.
The datasheet lists universal voltage operation (120-277 VAC, 127/250 VDC) but does not specify dimming capability. For projects requiring dimming, verify with the product spec sheet or consider a driver/controls option compatible with line-voltage LED luminaires and hazardous-location installations.
The fixture delivers 8000 lumens at 59W (approximately 135 lm/W), reducing energy consumption per area compared with legacy lighting. With IP66/IP67 and NEMA 4X protection, it withstands harsh environments, lowering cleaning and maintenance needs. The long-life copper-free aluminum housing minimizes corrosion-related outages, supporting longer maintenance intervals and predictable lifecycle costs.
Ideal for oil and gas, chemical processing, mining, and offshore or marine facilities, the MLLAW4N-UNV1-S903-P-M2 excels in hazardous locations requiring robust IP66/IP67 protection and Class I/II/III approvals. It suits high-bay, Enclosed process areas, and retrofit projects where reliable, compliant illumination with a narrow distribution is essential for safety and productivity.
