Quick Summary
MLLA4-UNV1-S891-M2 is a high-output LED linear light fixture for hazardous-area industrial facilities. Engineers often struggle to meet strict safety codes while maintaining reliable illumination in Class I/Division 2, Class II/Division 1, and Zone 2 locations. This luminaire carries Hazardous/Classified Locations ratings, IP66/IP67 protection, and a NEMA 4X enclosure for rugged environments. It operates on universal voltage (120-277 VAC or 127/250 VDC) with PF > 0.94 and 50/60 Hz. The 8000 lumens at 59 watts yields 135 lm/W efficiency, delivering energy savings and predictable brightness. Featuring flush ceiling mounting, diffused glass, copper-free aluminum, and 3/4" entries, it provides long-life, corrosion resistance, and uniform coverage in refineries, chemical plants, and other demanding facilities.
