High-output LED technology delivers 8000 lumens at 59W, achieving about 135 lm/W. This reduces energy costs and electrical load on aging distribution systems, critical in continuous industrial processes where uptime matters. Cool white light and a diffused glass lens provide uniform illumination and reduced glare in tight, high-heat environments, improving operator visibility and safety. The luminaire's IP66/IP67 and NEMA 4X ratings guard against water, dust, and corrosive atmospheres, lowering maintenance frequency and extending service intervals. Certification for NEC/CEC, Class I Division 2, and Zone 2 confirms regulatory compliance in hazardous locations, enabling faster project approval and downstream procurement. Copper-free aluminum with a painted white epoxy finish delivers rugged durability and corrosion resistance in harsh environments. Flush ceiling mounting and 3/4 inch entries simplify installation and enable rapid retrofits, while 347–480 Vac operation and 50/60 Hz support global facilities. With PF > 0.98 and cool-white tone, the fixture preserves lighting quality and reduces glow-related complaints, delivering consistent performance across shifts and seasons.
