Lumens and efficiency drive cost savings. The fixture delivers 4000 lumens at 132 lm/W, enabling lower wattage for the same light level and reducing energy costs across maintenance cycles. The cool white output supports accurate work and reduced eye fatigue in industrial environments while maintaining compact form with a 2 ft length. The consistent performance helps facilities meet productivity targets without compromise on illumination quality. Rugged certifications and protection drive compliance. Rated for Hazardous/Classified Locations with Class I Division 2, Zone 2, plus IP66/IP67 and NEMA 4X, it withstands dust, moisture, and washdowns in demanding settings. This reduces compliance risk and downtime in oil, gas, chemical, and maritime facilities while aligning with NEC/CEC standards. Corrosion resistance and durable materials improve lifecycle costs. Copper-free aluminum with a natural finish resists corrosion in harsh atmospheres, supporting longer service life in offshore, chemical, and litoral environments. Installation versatility and ease. Flush ceiling mounting and 3/4" entries simplify wiring and mounting, enabling faster retrofits and neater deployments in constrained spaces, with predictable installation footprint across regions. Electrical flexibility supporting global deployment. Operating from 120–277 VAC and 50/60 Hz, with 127/250 VDC options, this luminaire adapts to regional power systems, reducing the need for multiple SKUs and streamlining procurement. Optical design for broad visibility. A polycarbonate lens with wide distribution ensures uniform illumination across open work zones, improving safety and reducing hotspots in industrial environments.
