FAQs
When installing the DLLA4N-UNV1-S891-M2 in hazardous locations, ensure compliance with NEC/CEC standards and confirm Class I, Division 2 or Zone 2 ratings. Use the flush ceiling mounting method and 3/4 inch entry conduits for clean wiring approaches. The copper-free aluminum housing minimizes corrosion concerns in aggressive atmospheres, while IP66/IP67 protection guards against dust ingress and water exposure during routine maintenance.
The fixture outputs 8000 lumens at 59 watts, achieving approximately 135 lumens per watt. This combination delivers bright, high-quality cool-white (approximately 5000K class) illumination over a 4 ft length with a narrow optical distribution, reducing the number of fixtures needed and lowering energy consumption in demanding industrial settings.
Yes. The DLLA4N-UNV1-S891-M2 supports a wide input range of 120-277 VAC and 127/250 VDC, and operates at 50/60 Hz. This versatility simplifies retrofits and new installs across facilities with mixed electrical systems, reducing stock variety and installation time.
The luminaire is rated for Hazardous/Classified Locations with NEC/CEC compliance, including Class I, Division 2 and Zone 2 areas. It also carries a NEMA 4X enclosure rating and IP66/IP67 ingress protection, providing robust safety and regulatory alignment for challenging industrial environments.
Benefits include reduced maintenance downtime due to long LED life and rugged enclosure, lower energy costs from high lumens-per-watt efficiency, and fewer fixture replacements in harsh atmospheres. The flush-mount design simplifies servicing, while corrosion-resistant copper-free aluminum extends service intervals, contributing to favorable total cost of ownership in hazardous-location facilities.
