High-output LED performance delivers 8000 lumens at 59 watts, providing bright, uniform illumination with an efficiency of 135 lm/W. The lower power draw reduces energy costs and cooling requirements, improving overall facility efficiency. Ideal for long runs and large hazardous-area spaces where consistent visibility matters for safety and productivity. Protection you can trust translates to fewer field failures. IP67 and IP66 ratings, plus NEMA 4X housing, guard against dust, water, and corrosion in tough environments. The hazardous location certifications—Class I, Division 2 and Zone 2—align with NEC/CEC requirements, simplifying compliance during audits and installations. Flexible power options simplify retrofits. The DLLA4-UNV1 supports 120-277 Vac and 127/250 Vdc with 50/60 Hz operation, while the 4 ft flush-ceiling installation, 3/4" entry, and diffused polycarbonate lens ease mounting in cramped ceilings and congested electrical spaces. Copper-free aluminum construction with a natural finish reduces corrosion risk and extends service life in aggressive environments. Integral emergency battery back-up adds safeguarding for critical operations, supporting safety protocols and code compliance during power interruptions, which translates into reduced downtime and potential ROI in process-critical areas.
