Eaton HBA44571HRGEM1 Linear Fluorescent Light - IP66
Part Number: HBA44571HRGEM1
Quick Summary
HBA44571HRGEM1 is an Eaton Crouse-Hinds Pauluhn Apex linear fluorescent light fixture designed for harsh industrial environments. Facilities operating in chemical plants, refineries, and offshore installations struggle with unreliable luminaires that fail under vibration, moisture, or dust. This fixture delivers NEC/CEC compliance, IP66 ingress protection, and hazardous-location approvals (Class I, Division 2; Class II, Division 1; Class III), reducing compliance risk and downtime. With through-feed mounting, a 54W four-lamp configuration, and a flexible 120–277 VAC range, it supports scalable retrofits and energy-efficient operation in hazardous locations. Engineered with a tempered glass lens and a high-reflectance aluminum reflector, it minimizes maintenance and extends service life while maintaining robust performance in extreme environments.
