High luminous efficacy and output deliver bright, energy-efficient illumination that reduces energy costs and improves visibility on hazardous work surfaces. The 8000 lumens at 59W (approximately 135 lm/W) supports safer operation and higher productivity in open factory floor spaces and around critical processes. Wide voltage compatibility for 347–480 VAC and 50/60 Hz enables rapid deployment across global facilities without extensive electrical rework. Rugged, copper-free aluminum housing with a natural finish and glass lens resists corrosion in damp or chemically aggressive environments, extending service life and lowering maintenance intervals. The IP66 and IP67 ingress protection along with a NEMA 4X rating ensure reliable performance in wash-down and offshore conditions, reducing downtime and replacement costs. Narrow optical distribution minimizes glare and concentrates light where it’s needed, improving eye safety and asset illumination in confined areas. Ceiling or swivel mounting provides flexible alignment and simplifies retrofits, speeding installation and minimizing downtime during upgrades.
