High lumen output with efficient performance drives tangible business results. The fixture delivers 8000 lumens at 59 watts, achieving approximately 135 lm/W with a power factor greater than 0.94. This combination reduces energy costs while maintaining bright, uniform illumination across large hazard zones, supporting safer, more productive work environments in plants and refineries. Universal voltage input simplifies procurement and enables a single luminaire to service multiple sites, cutting stocking complexity and installation time for contractors. The 4 ft length with a diffused polycarbonate lens reduces glare and hotspots, enabling consistent lighting along long aisles, workcells, and mezzanine levels. Ceiling and swivel mounting options provide installation flexibility and faster retrofit projects, minimizing downtime during upgrades. The durable copper-free aluminum housing resists corrosion in harsh processes and dusty conditions, extending service life and lowering maintenance cycles. Integrated surge protection up to 10 kV guards against transient events, preserving lumen output and reducing unexpected failures in power-heavy industrial environments. Together, these features translate into lower total cost of ownership, improved compliance, and safer, more reliable facility operations.

FAQs
The fixture supports ceiling mounting with a swivel option and a 4 ft form factor. It includes 3/4 entry and a diffused polycarbonate lens, enabling straightforward integration into standard industrial ceilings and retrofit projects. This design simplifies alignment, reduces installation time, and accommodates flexible layouts in constrained or retrofitted hazardous-area spaces.
Yes. It is rated for Hazardous/Classified Locations per NEC/CEC, including Class I Division 2 and Zone 2, Class II Division 1, and Class III. With IP66/IP67 and NEMA 4X protection, it supports safe, compliant operation in harsh industrial sites such as petrochemical plants, water treatment facilities, and offshore platforms.
The luminaire delivers 8000 lumens at 59 watts, achieving about 135 lm/W with a power factor greater than 0.94. It operates on 120–277 VAC or 127/250 VDC and supports 50/60 Hz. The 4 ft length and diffused lens provide broad, even illumination suitable for general area lighting in industrial settings.
It offers IP66/IP67 ingress protection, a NEMA 4X enclosure, and Hazardous/Classified Location certifications per NEC/CEC, including Zone 2 and Division 1. An integrated surge protection module rated at or above 10 kV guards against transients, enhancing reliability in dusty, wet, or power-unstable environments.
With 8000 lm output at 59 W and 135 lm/W efficiency, energy costs are reduced while delivering bright, steady lighting. The copper-free aluminum housing resists corrosion, and the sealed IP-rated design minimizes ingress. Longer service life, fewer replacements, and surge protection contribute to lower maintenance intervals and a favorable return on investment for hazardous-area facilities.
