High efficacy and lumen output deliver 8000 lumens at 59 watts, equating to roughly 135 lumens per watt. This reduces energy consumption and cooling load, enabling lower operating costs in large manufacturing areas and warehouses. The narrow optical distribution provides focused illumination for task-critical zones, improving accuracy and reducing glare in control rooms, aisles, and workbenches. The luminaire employs a copper-free aluminum housing with a painted white epoxy finish and a polycarbonate lens, delivering superior corrosion resistance in harsh environments typical of chemical plants and refineries. Flush ceiling mounting with a 3/4 inch entry simplifies installation and aligns with existing industrial ceilings, while a 39 inch length minimizes fixture counts for long corridors and production lines. The unit supports universal voltage (120-277 VAC, 50/60 Hz) and 127/250 VDC, enabling straightforward retrofits and future-proofing across facilities. A high PF (>0.94) reduces reactive power and improves electrical efficiency in nearly any industrial distribution system. The product’s IP66/IP67 ratings and NEMA 4X enclosure ensure reliable operation against dust, water ingress, and corrosive atmospheres, addressing common compliance concerns and reducing unscheduled maintenance. By combining long life with robust mechanical protection and easy installation, it delivers a compelling total cost of ownership advantage for hazardous-location lighting deployments.
