High-output, efficient performance drives lower operating costs. Feature → Business Impact → Application: The MLLA4CS-UNV1-M2 delivers 8000 lumens at 59 watts (approximately 135 lm/W), enabling broader light coverage with fewer fixtures. This reduces energy spend and maintenance downtime while ensuring consistent illumination across long runs in manufacturing floors and processing plants. The result is improved productivity and safer work environments where high visibility is essential. The wide optical distribution supports uniform lighting in open areas and reads clearly in high-ceiling spaces, making it ideal for retrofits and new builds in industrial automation facilities. For operators, fewer lamps mean lower replacement cycles and simpler inventory management, especially in critical service zones.
