Feature → Business Impact → Application: High-output LED performance delivers 8000 lumens at 59W with an efficiency of 135 lm/W, reducing energy costs while maintaining bright, consistent illumination across large industrial spaces such as production lines and warehouses. This translates to lower operating expenses and fewer re-lamped cycles in demanding environments. Application: hazardous zones needing reliable, energy-efficient lighting. Feature → Business Impact → Application: Wide optical distribution and a glass lens provide uniform light with minimal hotspots, improving worker visibility and reducing glare-related fatigue on crowded shop floors and maintenance corridors. Application: areas requiring clear line-of-sight and safety-critical illumination. Feature → Business Impact → Application: Robust hazardous-location ratings (Class I Division 2, Zone 2; Class II Division 1; Class III), IP66/IP67, and NEMA 4X enclosure ensure code-compliant, corrosion-resistant operation in chemical plants, marine facilities, and mining sites. Application: harsh, damp environments with strict safety standards. Feature → Business Impact → Application: Universal voltage support (120–277 VAC, 127/250 VDC) simplifies multi-site installation and retrofits, reducing inventory diversification and sparing procurement delays. Application: multi-site facilities seeking flexible power options. Feature → Business Impact → Application: Copper-free aluminum construction with natural aluminum finish and a glass lens delivers durable, corrosion-resistant performance, extending service life in aggressive environments. Application: coastal, chemical, and heavy-industry settings. Feature → Business Impact → Application: Flush ceiling mounting and a 4 ft (39 in) length with 3/4 inch entry simplify installation in ceilings and tight retrofit projects, lowering labor costs and downtime. Application: spaces with ceiling constraints or retrofits requiring minimal structural modification. Feature → Business Impact → Application: Optional emergency battery-backup options documented (IF 1946) enable compliant egress lighting without additional retrofits, enhancing safety and ROI. Application: safety-critical zones requiring backup illumination during power outages.

FAQs

The MLLA4-UNV1-M2 supports flush ceiling mounting, 3/4 inch entries, and universal voltage 120-277 VAC (and 127/250 VDC), enabling straightforward installation in Class I, Division 2 or Zone 2 environments without specialized retrofits. Confirm enclosure rating (IP66/IP67) and respect distance to any flammable materials; follow the installation instructions (IF 1946) for backup configurations.
It delivers 8000 lumens at 59 watts with a high efficacy of 135 lm/W and a power factor greater than 0.94. The fixture operates on 50/60 Hz with a glass lens for visible-light quality, and supports both AC mains (120-277 VAC) and DC options (127/250 VDC) for versatile site installations.
Yes. With IP66/IP67 ingress protection, NEMA 4X enclosure, and hazardous-location certifications (Class I Division 2, Zone 2; Class II Division 1; Class III), the luminaire is designed for corrosive, wet environments typical of offshore rigs and marine facilities, meeting stringent safety standards.
The MLLA4-UNV1-M2 aligns with NEC/CEC requirements and is certified for Hazardous/Classified Locations, with IP66/IP67 protection and a NEMA 4X rating. This combination supports compliance in industrial plants, chemical processing facilities, and mining operations, simplifying regulatory documentation.
LED longevity and sealed construction reduce maintenance cycles and lamp replacement costs in harsh environments. The 8000 lumens output at 59W, high lumens-per-watt, and robust IP/NEMA ratings help lower energy consumption and downtime, delivering favorable total cost of ownership over multi-year operations.
