High reflectance reflector
Feature through-feed design with two 3/4 inch NPT hubs and bolted door enables fast, secure wiring and rapid servicing in tough environments. Business impact: reduces installation time, minimizes fault risks, and lowers maintenance costs, especially in facilities with limited access or strict safety protocols. Application: hazardous locations in oil & gas, chemical processing, and power generation sites benefit from a robust, serviceable luminaire that stays sealed under demanding conditions. Feature six-lamp 54W configuration with 4 ft lamp length and T5HO mini bi-pin lamps delivers high lumen output with fewer fixtures than smaller luminaires. Business impact: lowers total installed cost and simplifies inventory management while maintaining consistent illumination in long aisles or work cells. Application: manufacturing floors, warehouses, and outdoor-rated corridors where space and efficiency matter. Feature aluminum housing, polycarbonate lens, and a high reflectance reflector maximize durability and light efficacy. Business impact: improved resilience to impact and chemical exposure with enhanced light distribution, reducing energy waste. Application: environments with dust, splash zones, or chemical vapors where long service life matters. Feature ingress protection and hazardous area ratings including IP66, NEMA 4, and Hazardous/Classified Locations area classification. Business impact: proven protection against dust, water ingress, and corrosive atmospheres, enabling compliance with stringent standards. Application: outdoor or semi-enclosed industrial installations and plant exteriors. Feature wide voltage compatibility 120-277 VAC and 50/60 Hz. Business impact: supports mixed electrical infrastructure without rewiring or additional equipment, enabling phased upgrades. Application: multi-building facilities with diverse power footprints or retrofit projects where downtime must be minimized.

It operates on 120-277 VAC at 50/60 Hz, providing flexible power options for mixed plant footprints while maintaining a sealed, compliant housing.
Key specs include a six-lamp, 54W T5HO mini bi-pin configuration, 4 ft lamp length, 120-277 VAC input, 50/60 Hz frequency, aluminum housing, polycarbonate lens, and an IP66/NEMA 4 rated enclosure. This combination supports high lumen output with durable protection in challenging industrial environments.
Yes. The fixture is certified for Hazardous/Classified Locations with NEC/CEC alignment and rated IP66 for dust and water ingress protection, plus NEMA 4 structural protection. This makes it appropriate for Class I, Division 2 areas found in chemical plants, refineries, and similar facilities requiring robust safety compliance.
HBAB46574HRP carries Hazardous/Classified Locations area classification, NEC/CEC standards compliance, NEC hazardous ratings (Class I, Division 2; Class II, Division 1; Class III), IP66 ingress protection, and NEMA 4 enclosure. These certifications ensure safe operation in harsh industrial environments and ease regulatory alignment.
The 54W, 4 ft, six-lamp design reduces the number of fixtures required, lowering installation and maintenance costs. A high reflectance reflector and polycarbonate lens improve lumen delivery, reducing energy waste. Through-feed wiring and bolted-door access simplify servicing, contributing to shorter downtime, easier replacements, and a favorable total cost of ownership in hazardous locations.
