Eaton MLLA4-UNV34-M2 LED Light Fixture - IP66/IP67 Hazardous Locations
Part Number: MLLA4-UNV34-M2
Quick Summary
Eaton MLLA4-UNV34-M2 LED light fixture provides rugged, efficient illumination for hazardous-location facilities. In harsh environments, traditional lighting often suffers from moisture ingress, corrosion, and costly maintenance downtime. The fixture delivers dependable operation with IP66/IP67 ingress protection, NEMA 4X enclosure, and NEC/CEC compliance for Hazardous and Classified Locations. Its 59W consumption yields about 8000 lumens at 135 lm/W, helping facilities cut energy bills without sacrificing brightness. The universal 347–480 VAC supply, glass lens, and flush-ceiling mounting simplify installation in tight spaces while delivering wide optical distribution for consistent coverage. Copper-free aluminum construction with a natural finish provides corrosion resistance in challenging environments, supporting longer service life and lower lifecycle costs. This combination helps uptime targets and safety requirements while reducing maintenance overhead and total cost of ownership.

Energy efficiency drives real business value. With 8000 lumens at 59 watts (135 lm/W), this fixture lowers energy consumption and reduces cooling load, translating to lower operating costs on long-running production lines and continuous processes. In practice, facilities see meaningful ROI when upgrading from legacy fixtures in areas like processing, batching, and washdown zones. Compatibility and installation are streamlined by a universal 347–480 VAC supply, 50/60 Hz operation, 3/4" entry points, and a flush ceiling mounting that fits tight ceilings and confined spaces, speeding project timelines and minimizing retrofit risk. The long-life LED solution also reduces maintenance cycles in hazardous environments, where ladder work and frequent replacements are costly and risky. The 4 ft form factor, glass lens, and wide optical distribution ensure uniform coverage across workstations, eliminating hotspots and improving operator comfort. Durability is reinforced by copper-free aluminum and a natural aluminum finish that resist corrosion in aggressive atmospheres, lowering replacement frequency and lifecycle costs. Finally, the fixture’s robust enclosure—NEMA 4X and IP66/IP67 rated—meets NEC/CEC standards for Hazardous and Classified Locations, providing peace of mind for compliance-heavy installations and long-term reliability.
