Quick Summary

MLLA linear LED light fixture delivers efficient hazardous-location illumination for industrial facilities. Users frequently contend with corrosive environments, limited space, and stringent certifications in hazardous areas. This luminaire meets NEC/CEC requirements and maintains NEMA 4X durability while delivering IP66/IP67 ingress protection for reliable performance in wet, dusty, or explosive-prone settings. By combining 4000 lumens, 132 lm/W efficiency, and a neutral white output, it provides consistent visibility on production lines and during maintenance tasks. The flush ceiling mount, diffused glass lens, and copper-free aluminum housing simplify installation in retrofit projects and new builds alike. Compatibility with 347-480 Vac power and 2 ft length enables modular layouts that reduce wiring complexity and total installed cost.

FAQs

This model supports 347-480 Vac, a 2 ft length, and 3/4 inch entries with a flush ceiling mount, designed for Class I and II hazardous locations. For installation, ensure compliant wiring methods, proper conduit routing, and secure mounting with appropriate sealing to maintain IP66/IP67 protection. It is suitable for retrofit or new-construction projects in chemical plants, refineries, and other harsh environments.
The fixture operates at 347-480 Vac, 50/60 Hz, consuming 30W and delivering 4000 lumens with a efficacy of 132 lm/W. It features a high power factor (>0.95) and neutral white output. This combination supports energy efficiency, reduced operating costs, and reliable performance across typical industrial power distributions.
Yes. It is certified for hazardous/classified locations, including Class I, Division 1 and 2, Class II and III, with NEC/CEC alignment, IP66/IP67 ingress protection, and NEMA 4X durability. These certifications and protections are specifically designed for chemical processing, refining, and related environments where robust, compliant lighting is critical.
Key installation advantages include 3/4 inch entry points and a flush ceiling mount that minimizes fixture protrusion and simplifies wiring. The copper-free aluminum housing and diffused glass lens reduce corrosion and glare, extending service life. Maintenance intervals are extended by LED longevity and rugged construction, resulting in lower total cost of ownership in washdown-heavy facilities.
The 4000 lumen output with 132 lm/W efficiency delivers meaningful energy savings, while the NEMA 4X and IP66/IP67 ratings minimize downtime due to corrosion or washdowns. The long life of LED technology reduces relamping, and the rugged enclosure lowers replacement costs in demanding facilities, contributing to a favorable ROI over the fixture’s lifecycle.
