Quick Summary

MLLA4N-UNV34-S903D-WH-M2 LED linear light fixture provides high-output illumination for hazardous locations. Facilities often struggle to find luminaires that withstand dust, moisture, and explosive atmospheres while meeting strict safety standards. This unit supports Hazardous/Classified Locations with IP66/IP67 ratings and NEMA 4X protection, along with NEC/CEC compliance for global deployment. Operating on 347–480 VAC, it draws 59 W and delivers 8000 lumens at up to 135 lm/W, helping reduce maintenance intervals and energy costs while improving site visibility and worker safety. The copper-free aluminum housing, diffused polycarbonate lens, and painted white epoxy finish further enhance durability in harsh environments, enabling longer service life and lower total cost of ownership.
