FAQs

The MLLAN4N-UNV34-S903D-WH-M2 is designed for universal compatibility within the 347–480 VAC range, simplifying electrical installations across sites with varying supply voltages. This reduces the need for multiple variants and lowers stocking requirements, while maintaining steady lumen output and color quality in demanding environments.
This fixture carries NEC/CEC compliance and hazardous-location ratings, including Class I Division 2 and Zone 2, along with a NEMA 4X enclosure and IP66/IP67 protection. These certifications ensure safe operation in potentially explosive atmospheres and harsh outdoor or wash-down environments, reducing regulatory risk and enabling compliant installations.
Yes. The unit is designed for flush ceiling mounting with a 4 ft form factor, which supports clean integration in spaces with limited headroom or modular ceilings. The 3/4" entry size also facilitates flexible wiring options, making retrofits and new-builds faster and more straightforward.
The fixture meets NEC/CEC standards and is certified for Hazardous/Classified Locations (Class I Division 2; Zone 2; Class II Division 1; Class III). It also carries NEMA 4X and IP66/IP67 ratings. These certifications verify safe operation in hazardous environments, protect against environmental ingress, and support industrial facility compliance programs.
The combination of 8000 lm output at 59 W (135 lm/W) and a long service life reduces energy spend and maintenance visits. The robust enclosure minimizes corrosion and moisture ingress, lowering replacement frequency. For plants with hazardous locations, this translates to lower downtime, improved uptime, and a faster payback on retrofit projects.
