Quick Summary
MLLAW4N-UNV34-S891-P-M2 is an LED linear light fixture engineered for hazardous locations and industrial facilities. Engineers often struggle with reliable, maintenance-heavy lighting in explosive atmospheres, which can drive downtime and safety risk. This fixture carries robust protections for hazardous areas, including IP66/IP67 ratings and NEMA 4X construction, enhancing durability and compliance. It delivers warm white illumination with high efficiency (8000 lumens at 135 lm/W) and a wide operating voltage range (347–480 VAC), enabling flexible integration across systems. By combining superior ingress protection with a compact, flush-ceiling design, it reduces lifecycle costs while meeting NEC/CEC standards and site-specific classifications. This makes it a strong fit for refineries, chemical plants, and other demanding environments while supporting long-term operational efficiency.
