Feature → Business Impact → Application: The DLLA4N-UNV34-S903-M2 uses a copper-free aluminum housing with a polycarbonate lens, delivering corrosion resistance and durable performance in corrosive industrial environments, reducing replacement cycles for offshore and chemical plants. Feature → High lumens at 8000 and efficiency of 135 lm/W translates to lower total installed power for the same illumination level, cutting energy costs and easing heat management in crowded electrical rooms. Feature → 347-480 VAC voltage with 50/60 Hz compatibility supports global facilities and reduces the need for multiple transformers, enabling simpler procurement and faster installations at multi-site operations. Feature → Narrow optical distribution and 4 ft length provide focused lighting along aisles and work benches, improving worker safety and inspection accuracy. Feature → 3/4" entry options and flush ceiling mounting streamline installation in drop-ceiling or open-frame layouts, reducing labor time and disturbance to ongoing production. Feature → IP66/IP67, NEMA 4X, and hazardous-location ratings ensure compliance with industrial safety standards, minimizing risk and avoiding retrofits during audits. Feature → 59W power draw and a PF > 0.98 help meet efficiency targets and utility incentives, supporting sustainability reporting and lifecycle cost reductions. Feature → 39 in length and 7.13 in width enable installation in long runs, providing consistent lighting with fewer fixtures and better maintenance planning. Feature → Cool white color temperature improves visual clarity for maintenance tasks and quality control, boosting productivity and reducing operator error. Feature → Copper-free aluminum and natural aluminum finish offer robust durability while maintaining a lightweight footprint for retrofit projects and new builds.
