Built around 8000 lumens at 59 watts with an efficient 135 lm/W rating, this fixture delivers bright, uniform illumination over large areas while keeping energy use low. In a manufacturing or processing plant, that efficiency translates to measurable reductions in electricity cost and cooling load, while maintaining compliance with lighting standards. With a wide voltage range of 347-480 VAC at 50/60 Hz and a 4 ft form factor, it integrates into standard industrial power distributions without complex transformers. The flush ceiling mounting and 3/4" entries simplify installation in existing ceilings, reducing retrofit time and operational disruption. Rugged construction uses copper-free aluminum with a natural finish and a diffused glass lens, delivering IP66/IP67 ingress protection and NEMA 4X durability for washdown environments and corrosive settings. This combination safeguards against dust, water jets, and harsh chemicals, ensuring long service life in challenging sites. Designed to meet NEC/CEC requirements and hazardous-location classifications such as Class I Division 2; Zone 2; Class II Division 1; Class III, the luminaire minimizes regulatory risk while supporting compliant upgrades. With PF > 0.98 and 8000 lumens, the fixture maintains stable performance and reduces maintenance cycles, contributing to a favorable return on investment for retrofit programs and new installs.

FAQs

This luminaire is designed for flush ceiling mounting with 3/4" entry points and a 4 ft length. It operates on 347-480 VAC at 50/60 Hz and weighs about 23.5 lb, which influences ceiling support and mounting hardware choices. Ensure enclosure sections and wiring pathways are rated for Class I, Division 2 / Zone 2 environments and that the installation complies with NEC/CEC requirements for hazardous locations.
The fixture delivers 8000 lumens with a high efficacy of 135 lm/W and a power factor greater than 0.98, providing bright, uniform illumination with minimal energy wasted. The neutral white light enhances visibility for detailed inspection tasks, while the wide optical distribution reduces shadows in large work areas, improving operator safety and productivity.
Yes. The MLLAN4-UNV34-S891-M2 is rated for Hazardous/Classified Locations with NEC/CEC compliance, including Class I Division 2 and Zone 2, and additional ratings for Class II Division 1 and Class III. It also features NEMA 4X and IP66/IP67 protection, making it suitable for challenging industrial environments and washdown conditions.
The IP66/IP67 and NEMA 4X protection reduce ingress and corrosion risks, extending service life in harsh environments. NEC/CEC compliance and hazardous-location certifications minimize regulatory risk, simplify asset management, and support facility-wide safety programs. Long life and high reliability translate to lower maintenance frequency and fewer replacements compared with traditional lighting.
Energy efficiency (59W) and high lumen output (8000 lm) yield significant energy savings versus older luminaires, while the sturdy construction reduces replacement and maintenance costs. The combination of low maintenance and improved lighting quality enhances productivity and safety, delivering a favorable total cost of ownership over the life of the installation.
