Eaton Specification Sheet - HPS44570
Hazardous-area protection is built in with an IP66-rated enclosure and NEMA 4X construction, delivering reliable performance in Class I, Division 2, Class II, Division 1 and Class III environments. The business impact is clear: extended service life and reduced failure-related downtime in harsh facilities. This is ideal for applications such as chemical processing or offshore operations where ingress protection directly translates to lower maintenance costs and fewer unscheduled outages. The 4-lamp 54W T5HO mini bi-pin configuration provides high light output per fixture while maintaining energy efficiency, reducing energy spend and cooling load in large interiors like washrooms, labs, and warehouses. The quick-release design minimizes relamping time, improving maintenance crew productivity and equipment uptime in overhead installations. Compatibility with 120-277 VAC and 50/60 Hz ensures seamless integration with existing electrical systems, supporting faster project timelines and predictable lifecycle costs. The 304 stainless steel housing and acrylic lens resist corrosion and impact, supporting long-term performance in challenging environments and simplifying inspection routines for facilities managers.
