Feature → Business Impact → Application. The HPA43775L uses a 3-lamp, 4 ft T8HO RDC configuration delivering 48W of efficient lighting, reducing energy consumption while maintaining high lumen output for critical zones in chemical plants and refineries. This translates to lower operating costs and improved visibility for operators in hazardous environments. Installation benefits include pendant mounting, through-feed wiring, and 3/4" NPT hubs with quick-release access, enabling rapid retrofit and simplified maintenance in constrained spaces such as pump rooms and outdoor enclosures. The aluminum housing with an acrylic lens provides robust ingress protection (IP66) and NEMA 4 protection, ensuring reliable operation during washdown cycles and in dusty or corrosive atmospheres. Compliance with NEC/CEC standards and hazardous-area classifications reduces regulatory risk and accelerates commissioning across multiple site facilities. The fixture’s universal 120–277 VAC supply and 50/60 Hz compatibility supports fleet-wide standardization, lowering spare-part inventories and procurement complexity.
