Material and enclosure durability drive long-term value in harsh environments. The 304 stainless steel housing resists corrosion in washdown areas, offshore facilities, and chemical plants, reducing maintenance frequency and total cost of ownership. This translates to fewer replacements and downtime, improving line productivity in critical operations. Hazardous-location certifications provide immediate compliance confidence. With NEC/CEC classifications, Class I, Division 2, Class II, Division 1 and 2, and Class III ratings, combined with IP66 and NEMA 4X enclosures, users can deploy this fixture where ignition risks and harsh conditions are present, avoiding costly retrofits and ensuring worker safety. Electrical versatility supports site-to-site deployment. The 120–277 VAC, 50/60 Hz supply and 4 ft, 2-lamp T5HO mini bi-pin configuration deliver consistent lumen output while simplifying stock needs and maintenance planning across plants, refineries, and processing facilities. Installation efficiency and ease of maintenance are enhanced by design choices. A pendant mounting option, bolted door, through-feed capability, and 1/2" entry hubs (4 NPT) streamline wiring, reduce install time, and enable fast lamp replacement with lamps included in the package. Lifecycle performance and operational reliability matter in demanding industries. The acrylic lens provides clear, impact-resistant illumination, while 54 W per fixture delivers adequate light with lower energy consumption, helping facilities meet sustainability targets without compromising visibility.
