FAQs

Yes. The MLLAW4-UNV34-M2 is designed for flush ceiling mounting with 3/4" entry points, making it straightforward to retrofit into existing industrial ceilings. Its copper-free aluminum housing and glass lens sustain performance in hazardous locations, while the 39 inch length and 7.13 inch width help match standard mounting footprints. Ensure power supply is within 347–480 VAC and that the installation complies with NEC/CEC requirements for Class I, Division 2 or Zone 2 environments.
The fixture operates at 347–480 VAC, 50/60 Hz, with a wattage of 59W and a lumen output of 8000, delivering about 135 lm/W. The power factor is rated >0.98, supporting efficient power usage and reduced utility charges. These specifications enable scalable lighting design for large areas while maintaining high-quality illumination and energy performance in demanding facilities.
This model is certified for Hazardous/Classified Locations under NEC/CEC, with a NEMA 4X enclosure and IP66/IP67 protection. It supports Class I, Division 2 and Zone 2 classifications, ensuring safe operation in potentially explosive atmospheres. Compliance with these standards reduces risk and simplifies procurement for regulated industries such as oil, gas, and chemical processing.
The fixture uses copper-free aluminum with a natural finish for corrosion resistance and structural integrity, complemented by a glass lens for impact resistance and clarity. The IP66/IP67 rating protects against dust and water ingress, while the 4X enclosure provides robust protection in harsh environments. This combination extends service life and reduces maintenance cycles in marine, offshore, or chemical processing facilities.
With long-lumen maintenance and high energy efficiency, facilities can expect lower energy bills and fewer lamp replacements. The wide 4 ft form factor and 8000 lumen output reduce the number of fixtures needed for large spaces, cutting installation and ongoing maintenance labor. The robust certification and enclosure also minimize downtime due to environmental exposure, contributing to a favorable total cost of ownership.
