Special features
Integral emergency battery back-up
Integral emergency battery back-up ensures continuous illumination during outages, reducing downtime in hazardous locations. This improves personnel safety and maintains visibility for critical operations during power interruptions. Applications include Class I, II, Division 1 environments in petrochemical plants, refineries, and offshore facilities.\n\nWith 8000 lumens at 59 watts and 135 lumens per watt, the MLLA delivers bright, efficient lighting with lower operating costs. The diffused polycarbonate lens provides wide distribution, ensuring uniform coverage across long runs and reducing the need for additional fixtures. This combination supports retrofit projects and new builds where consistent brightness is essential.\n\nCopper-free aluminum construction with a natural aluminum finish resists corrosion in harsh environments. A flush ceiling mounting method reduces fixture protrusion and facilitates fast, safe installation in crowded industrial ceilings. The 3/4-inch entry size simplifies conduit connections and maintenance access.\n\nIP66/IP67 protection and a NEMA 4X enclosure guard against dust, water, and impact in demanding settings. NEC/CEC compliance and hazardous-location ratings ensure readiness for Class I/II, Division 1 and Zone 2 scenarios. The 50/60 Hz operation and wide voltage range support global installations.\n\nCompatibility with 120-277 VAC and 127/250 VDC enables flexible power sourcing, while the 4 ft length and 39-inch depth suit long runs in industrial spaces. The 59W rating paired with a high PF (>0.94) reduces energy waste, contributing to lower operating costs over the fixture's life.
