High efficiency and dense illumination drive lower operating costs: the DLLA4N-UNV1-S903D-M2 delivers 8000 lumens at 135 lm/W, enabling brighter work environments while consuming only 59 watts. This translates to meaningful energy savings and reduced cooling loads in manufacturing and processing plants. The business impact is improved uptime and safer worker visibility in hazardous locations, supported by UL NEC/CEC compliance, and IP67/IP66 protection alongside a NEMA 4X rating for rugged environments. The product’s 4 ft length, 3/4" entry, and flush ceiling mounting design streamline retrofit projects and new installations, minimizing downtime and enabling compliant conduit routing in tight spaces. Copper-free aluminum construction enhances corrosion resistance in harsh industrial atmospheres, reducing maintenance costs over the asset lifecycle. The lens is diffused polycarbonate for uniform light with low glare, improving process accuracy without increasing glare or shadows in critical zones. Thermally-efficient design and a high PF (>0.94) ensure stable performance across 50/60 Hz and broad voltage ranges, enabling multi-site deployment and simplifying procurement across global operations.0
