Quick Summary

MLLA2-UNV1-S891-P-M2 is a linear LED light fixture for hazardous-location industrial facilities. In challenging environments, unreliable protection and maintenance complexity threaten uptime. It carries IP66/IP67 ingress protection, NEMA 4X corrosion resistance, and NEC/CEC hazardous-location ratings (Class I Division 2, Zone 2) to support safe, compliant operation. With 4000 lumens at 132 lm/W in a 2 ft form factor and a diffused glass lens, it delivers crisp, uniform illumination while reducing glare. The copper-free aluminum housing and gray epoxy finish resist harsh industrial conditions, while universal 120-277 VAC and 127/250 VDC input simplify installation and stocking. This combination delivers lower lifecycle costs and faster ROI for plant upgrades and retrofits.

FAQs

Installation should follow the IF 1932 instruction sheets and use the flush ceiling mounting configuration for a secure, aesthetic ceiling integration. The unit supports 2 ft length with 3/4 inch entry, and works on universal voltage (120-277 VAC, 127/250 VDC). Always de-energize circuits before mounting and verify enclosure integrity after installation in Class I Division 2 or Zone 2 environments.
The MLLA2-UNV1-S891-P-M2 delivers 4000 lumens at 132 lm/W, consumes 30 W, and accepts 120-277 VAC or 127/250 VDC with 50/60 Hz operation. The power factor is greater than 0.92, and the light uses a diffused glass lens with a wide optical distribution to ensure even coverage across the workspace.
Yes. It is certified for hazardous locations with NEC/CEC ratings including Class I Division 2 and Zone 2, plus a NEMA 4X rating and IP66/IP67 protection, making it appropriate for oil & gas, chemical processing, and other harsh industrial settings that demand compliant, durable lighting.
This fixture features IP66/IP67 ingress protection, NEMA 4X enclosure rating, and NEC/CEC hazardous-location certifications (Class I Division 2, Zone 2, Class II Division 1, Class III). These certifications support safe operation in demanding environments and simplify regulatory compliance during upgrades.
LED efficiency reduces energy costs and runs cooler than legacy luminaires, while long life and rugged housing lower replacement and maintenance needs. Universal voltage simplifies project scoping, lowering stocking complexity and enabling faster retrofits with predictable ROI in plants, refineries, and other duty-cycle environments.
