Hazardous-location certification and IP66 protection mitigate risk in demanding environments, delivering compliant operation for oil and gas, chemical, and mining facilities while reducing downtime. The rugged aluminum housing paired with a NEMA 4 rating resists corrosion and weathering, extending service life in washdown zones and outdoor installations, which lowers lifecycle costs. Through-feed wiring with two 1/2" hubs enables flexible routing and minimizes field splices, accelerating installation and future upgrades in retrofit projects. The 54W two-lamp configuration using T5HO mini bi-pin lamps provides efficient lighting output for 4 ft fixtures, delivering consistent brightness with minimal energy use across 50/60 Hz systems. The emergency battery back-up ballast ensures safe egress lighting during power outages, enhancing safety compliance without additional equipment. Overall durability, simple maintenance access via bolted doors, and a compact 50.59 in length fit tight plant spaces while supporting scalable deployments in large facilities.
