High-lumen efficiency: 8000 lumens at 59 watts with 135 lm/W reduces the number of fixtures needed for large areas, delivering lower energy costs and simpler maintenance in long-run installations. This translates to faster ROI in process areas and walkways where consistent, bright illumination is critical for safety and productivity. Hazardous-location readiness: IP66/IP67 protection and NEMA 4X enclosure ensure reliable operation in corrosive or explosive environments, enabling safer compliance in oil, gas, and chemical facilities while minimizing unscheduled maintenance. Integrated surge protection: ≥10kV protection guards against transient events common in industrial power networks, reducing fixture downtime and extending life in facilities near heavy equipment or power drops. Robust construction: copper-free aluminum housing with a glass lens withstands corrosion and thermal cycling, supporting durable service in outdoor or harsh indoor spaces. Compatibility and installation: 39 in length with 4 ft lamp length, 3/4" entry, and universal voltage (120–277 VAC, 50/60 Hz) streamline retrofits and new builds, with installation sheets and photometric data readily available to accelerate commissioning.
