Quick Summary

MLLAW4N-UNV1-S891-M2 is a high-output linear LED light fixture for hazardous industrial locations. In demanding environments, outages from aging fixtures interrupt production; this design reduces downtime with rugged housing and long-life LEDs. It meets NEC/CEC requirements and hazardous location ratings such as Class I, Division 2; Zone 2, and IP66/IP67 with a NEMA 4X enclosure. Designed for 120-277 VAC and 127/250 VDC with 50/60 Hz operation, it enables flexible retrofits across facilities. For engineers, the 4 ft length, narrow optical distribution, and diffused glass lens support uniform lighting on wide shop floors while minimizing glare and hot spots, improving safety and productivity.

The fixture delivers 8000 lumens at 59 W, achieving 135 lm/W to cut energy consumption while maintaining bright, consistent illumination across work areas. This efficiency translates to tangible operating-cost reductions, especially in multi-shift operations common in manufacturing and process facilities. With IP66/IP67 protection and a NEMA 4X enclosure, the unit withstands dust, moisture, and chemical exposure, reducing maintenance cycles and extending service life in coastal or chemical environments. Copper-free aluminum housing and a diffused glass lens provide durable performance without corrosion risk, while a narrow optical distribution concentrates light on critical surfaces, decreasing glare and boosting task accuracy. Flush ceiling mounting and a 39 in overall length simplify retrofits in constrained spaces, accelerating installation timelines. Electrical compatibility covers 120-277 VAC and 127/250 VDC at 50/60 Hz, enabling cross-region deployments and standardized maintenance routines. NEC/CEC compliance and hazardous-location ratings support safe operation across plant sectors, delivering a strong ROI through reliability, safety, and reduced downtime.
