MLLAN4-UNV1-S891-M2 uses a high-efficiency LED source to deliver 8000 lumens at 59 W, achieving 135 lm/W and a PF > 0.94. This translates to lower energy consumption and reduced cooling loads in demanding facilities, while maintaining consistent color and brightness for critical work areas. The wide optical distribution (Wide) and diffused glass lens minimize glare and ensure uniform illumination across large planes, which improves worker safety and reduces eye strain in maintenance bays and process floors. Copper-free aluminum construction with a natural finish delivers corrosion resistance in humid or chemical environments, supporting longer life in hazardous locations. The unit’s 4 ft length, 39 in overall depth, and 3/4" entry capability enable straightforward flush-ceiling installation and easy daisy-chaining with existing luminaire runs. Rated IP66/IP67 and NEMA 4X, it remains sealed against dust and water ingress, meeting Class I, Division 2, Zone 2, and Class II, Division 1 requirements for compliant industrial lighting. Its broad voltage range, 120–277 VAC and 127/250 VDC, plus 50/60 Hz capability, supports global deployments and reduces inventory complexity for multinational facilities. This fixtures’ robust performance contributes to measurable cost reductions through lower maintenance frequency, fewer replacements, and predictable illumination in hazardous-area operations. In short, it combines reliability, compliance, and energy efficiency to support safer, more productive industrial environments.
