Quick Summary

MLLAN4-UNV34-S903-WH-M2 linear LED light fixture from Eaton Crouse-Hinds is designed to deliver reliable hazardous-location illumination for industrial facilities. In harsh environments, maintenance downtime and corrosion exposure drive costs and risk, so a rugged, long-life luminaire is essential. This fixture meets hazardous-location requirements including Class I Zone 2 and related NEC/CEC ratings, with IP66/IP67 protection and a NEMA 4X enclosure to withstand washdowns and contamination. Its 4 ft form factor, neutral white output, and 8000 lumens at 59 watts enable high-visibility lighting with fewer fixtures. With 347–480 VAC operation and flush-ceiling mounting, it supports scalable deployments while reducing wiring complexity and total ownership costs. Secondary benefits include compatibility with emergency-backup configurations and wide distribution for plant-wide coverage.

High lumen output meets demanding industrial spaces while preserving energy efficiency, reducing fixture count and lowering operating costs. Feature → Business Impact → Application: 8000 lumens at 59W delivers 135 lm/W efficiency, enabling brighter work areas in chemical plants and refineries without scale-up in power consumption; apply this in long corridors or open-process areas to improve safety and productivity. Feature → Business Impact → Application: 4 ft length with flush ceiling mounting simplifies installation in constrained ceilings and minimizes interference with equipment; ideal for retrofits in existing industrial mezzanines or maintenance corridors. Feature → Business Impact → Application: 347–480 VAC input broadens electrical compatibility across facilities, reducing the need for local transformers and enabling quick, cost-efficient deployments in mixed-voltage sites. Feature → Business Impact → Application: IP66 IP67 and NEMA 4X protection provide reliable operation in washdown zones and dusty environments; use in chemical processing, mining, and offshore applications to extend service life and compliance. Feature → Business Impact → Application: Copper-free aluminum and a polycarbonate lens resist corrosion and impact, lowering maintenance costs in harsh environments and extending fixture longevity. Feature → Business Impact → Application: Optional emergency battery-backup via the MLLA-M2 installation path supports critical lighting during power interruptions, improving safety and uptime in safety-critical zones.
