Quick Summary

MLLA4-UNV34-P-M2 is a high-efficiency LED light fixture for hazardous-location industrial illumination in chemical plants and refineries. Design challenges like corrosive atmospheres and frequent washdowns are addressed with IP66/IP67 protection and a glass lens. Key certifications include NEC/CEC compliance, Hazardous/Classified Locations ratings, NEMA 4X enclosure, and IP66/IP67 ingress protection. This combination supports longer service life and reduced maintenance, while enabling rapid installation across 347–480 VAC networks. Beyond compliance, the fixture delivers 8000 lumens at 135 lm/W for reliable, energy-efficient site illumination. Its flush ceiling mounting and 4 ft length simplify routing and reduce field labor during retrofits. Copper-free aluminum housing and painted gray epoxy finish resist corrosion in harsh environments, while a glass lens protects performance in tough industrial spaces.

FAQs

Installers should use flush ceiling mounting with the 4 ft fixture length and 3/4" entry as specified, ensuring all terminations and wiring stay within the rated enclosure. Follow NEC/CEC guidelines and the IF1932/IF1946 installation sheets for wiring practices, conduit entries, and mounting hardware appropriate to Class I, Division 1/Zone 2 environments to maintain compliance and safety.
The MLLA4-UNV34-P-M2 operates at 347–480 VAC with a 50/60 Hz frequency rating and consumes 59 W while delivering 8000 lumens (approximately 135 lm/W). It supports direct integration with standard industrial power systems, reducing the need for transformers and simplifying panel design during upgrades or retrofits.
Yes. It is rated for Hazardous/Classified Locations with NEC/CEC compliance and Class I, Zone 2 (as well as Class II/Division 1 and related classifications). The unit also carries NEMA 4X enclosure protection and IP66/IP67 ingress protection, making it appropriate for demanding industrial and marine environments with rigorous safety standards.
IP66/IP67 protection provides robust ingress resistance against dust and powerful water jets, while NEMA 4X enclosures add corrosion protection. This combination minimizes washdown-related wear, reduces cleaning-related downtime, and extends service life in wet, dusty, or chemical environments common in oil, gas, and chemical processing facilities.
Expect faster payback due to lower energy use (8000 lm at 59 W), reduced maintenance from durable Copper-free aluminum housing, glass lens protection, and long service life under harsh conditions. The 347–480 VAC compatibility also lowers retrofit costs, while the wide distribution and high PF (>0.98) reduce lighting-related energy waste and improve worker productivity.
