FAQs

Installation supports ceiling or wall offset mounting with a 3/4" entry and a 39 in housing, enabling seamless 4 ft row configurations. For hazardous locations, follow Class I Division 2 or Zone 2 requirements, using approved conduits, gaskets and seals to preserve IP67/NEMA 4X integrity and maintain certification compliance.
The fixture operates on 120–277 VAC or 127/250 VDC with 50/60 Hz, drawing 59 W to produce 8000 lumens, equating to about 135 lm/W. It maintains a power factor greater than 0.94 and uses a diffused polycarbonate lens for wide light distribution, suitable for general-area industrial illumination.
Yes. It is designed for hazardous/classified locations, with NEC/CEC compliance for Class I Division 2 and Zone 2, plus Class II Division 1 and Class III ratings. The IP67/IP66 protection and NEMA 4X enclosure provide robust ingress protection required in chemical processing and other demanding environments.
The luminaire aligns with NEC/CEC hazardous-location standards and ANSI/NEMA requirements, with UL-related Canadian certifications available. Documentation includes installation instructions, a specification sheet, and catalog pages validating construction, IP/NEMA ratings, and emergency-battery features to support audit trails and compliance.
LED reliability, integrated emergency battery, and long-life components reduce maintenance cycles and downtime. Energy efficiency lowers operating costs, while the rugged enclosure minimizes replacement intervals in harsh sites. Warranty coverage typically follows manufacturer terms, and the emergency-backup feature supports compliance with life-safety codes, delivering clear ROI in uptime-critical operations.
