Rugged housing and corrosion resistance deliver real business value. The fixture uses copper-free aluminum with a natural finish and dual IP ratings (IP66/IP67) plus NEMA 4X construction, which translates to fewer field failures in washdown and offshore environments. In hazardous locations across mining, chemical plants, and power generation, this durability keeps maintenance windows short and uptime high. Integral emergency battery creates a safety-critical backup that keeps exit paths illuminated during outages. This capability meets life-safety requirements without adding external battery packs, reducing installation complexity and total cost of ownership. Flush ceiling mounting and a 4 ft length simplify installation and alignment across long runs. The 3/4" entry size supports common conduit fittings, while a wide optical distribution reduces the number of fixtures required for uniform coverage. High efficacy at 135 lm/W and 8000 lumens at 59W minimizes energy use and heat load. With voltage tolerance of 120-277 Vac and 127/250 Vdc and 50/60 Hz, it adapts to site power conditions, reducing stocking and commissioning time. Maintenance benefits include a polycarbonate lens that resists impact and UV exposure, and the natural aluminum finish with copper-free construction supports long service life in mixed-metal systems. The result is a reliable, cost-effective solution for industrial facilities seeking consistent illumination, regulatory compliance, and predictable budgeting.

FAQs

The fixture includes NEC/CEC compliant hazardous-location approvals with Class I, Division 2 and Zone 2 ratings, plus Class II Division 2 and Class III where applicable. It carries IP66/IP67 ingress protection and a NEMA 4X enclosure for rugged washdown environments, supporting compliance in industrial plants and marine settings. These certifications help ensure safe operation in hazardous areas while aligning with typical project specifications.
Yes. The DLLA4-UNV1-S903-EM1-M2 is designed for flush ceiling mounting and measures 4 ft in length with a 3/4" entry. This configuration minimizes protrusion, simplifies installation along long runs, and reduces mounting complexity in constrained ceilings commonly found in processing facilities, chemical plants, and offshore modules.
The fixture operates at 120-277 Vac or 127/250 Vdc, with a 50/60 Hz frequency, and consumes 59W while delivering 8000 lumens. Its efficacy is 135 lm/W, enabling lower energy use compared with legacy luminaires. The wide voltage tolerance supports variable power environments and reduces voltage-related commissioning time.
Yes, this model includes an integral emergency battery back-up. The built-in emergency function maintains illumination during power interruptions, supporting safe egress and compliance with life-safety requirements in hazardous locations without the need for external backup modules.
Key benefits include IP66/IP67 protection and a NEMA 4X enclosure, which resist water, dust, and corrosion in harsh washdown conditions. Copper-free aluminum construction reduces galvanic corrosion, and a long 4 ft form factor reduces fixture counts. The polycarbonate lens withstands impact, while the integral emergency battery minimizes maintenance scheduling and total cost of ownership.
