The DLLA4N-UNV34-S903D-M2 uses a diffused polycarbonate lens to deliver uniform illumination with minimal glare, improving operator visibility and reducing eye strain in hazardous environments. This translates to higher productivity on long runs and safer work practices on the factory floor. The fixture delivers 8000 lumens at 135 lm/W while drawing only 59 watts, enabling meaningful energy savings and brighter coverage across expansive spaces like warehouses and processing lines. Its wide 347–480 VAC supply and 50/60 Hz compatibility simplify system design and reduce a dedicated sub-feed requirement, streamlining installation and commissioning. With IP66/IP67 protection and NEMA 4X enclosure, it withstands dust, moisture, and corrosive environments, reducing maintenance cycles in chemical plants and offshore facilities. Copper-free aluminum construction further enhances corrosion resistance in challenging environments, supporting longer service life. The flush ceiling mounting and 4 ft length optimize sightlines, reduce dirt build-up, and simplify retrofits in existing catwalks and ceilings, making it a practical upgrade for hazardous-location lighting programs.
