High efficiency and brightness drive lower operating costs and improved visibility in large industrial spaces; 8000 lumens at 59W yields about 135 lm/W, reducing energy consumption while maintaining ample illumination for critical tasks. This is especially valuable in hazardous locations where reliable lighting reduces safety incidents and downtime; the IP66/IP67 rating and NEMA 4X enclosure ensure weather and chemical exposure resistance, simplifying compliance and reducing maintenance calls. The wide optical distribution and polycarbonate lens deliver uniform coverage across work zones, enhancing operator awareness and reducing glare-related errors in process plants. Copper-free aluminum construction plus a natural aluminum finish delivers corrosion resistance and longevity in challenging environments, supporting longer service intervals and a lower total cost of ownership. The 4 ft length with a 2 in pole-mount option enables straightforward retrofits and retrofit-ready installations, saving time and labor during upgrades or new installations. The fixture’s voltage flexibility—120-277 Vac and 127/250 Vdc—and PF > 0.94 improve power quality, minimize stray currents, and reduce the need for additional power conditioning.
