It’s ideal for chemical plants, refineries, and offshore facilities where certified protection is required. Its IP66/IP67 ratings and NEMA 4X housing provide robust protection against dust, water, and corrosive environments, improving uptime in demanding installations.
The fixture operates across a broad voltage range of 120–277 VAC and 127/250 VDC, with a 50/60 Hz frequency rating. This flexibility simplifies electrical design, enables cross-site deployment, and reduces the number of SKUs needed for regional projects, supporting quicker installations and lower inventory costs.
The MLLA M2 measures 39 inches in length with a width of 7.13 inches and a height of 4.42 inches, and it weighs 23.5 pounds. This size and weight support straightforward overhead mounting in standard ceiling spaces and align with typical 4 ft linear lighting layouts used in industrial retrofit projects.
It provides Hazardous/Classified Location ratings per NEC, NEC/CEC standards, NEMA 4X protection, and IP66/IP67 ingress protection. These certifications ensure safe operation in hazardous environments, protect against dust and water ingress, and support regulatory compliance for industrial and marine applications.
With flush ceiling mounting, 3/4" entry, and a 4 ft form factor, installation is faster and neater, reducing labor time. The LED technology delivers high lumens at low wattage (8000 lm / 59 W) and a long life, which lowers maintenance cycles and energy costs, delivering a favorable return on investment over the fixture’s lifetime.
