FAQs

Installation is streamlined for hazardous locations thanks to a pole-mount design with a 1.50 inch diameter mount compatible with standard industrial poles. The fixture length is 39 inches with a compact footprint that fits walkways and process areas. The assembly supports safe wiring within the voltage range of 120-277 VAC and 127/250 VDC, reducing field modifications and enabling quicker commissioning in new or retrofit projects.
Yes. The MLLA4P15-UNV1-S903-M2 operates on 120-277 VAC and can handle 127/250 VDC, with a wide 50/60 Hz frequency range. It delivers 8000 lumens at 59 watts, equating to about 135 lumens per watt, and a power factor better than 0.94, supporting stable performance and grid compliance across diverse facilities.
The fixture is rated for Hazardous/Classified Locations per NEC/CEC, including Class I, Division 2 and Zone 2, plus Class II and III equivalents. It carries NEMA 4X as well as IP66 and IP67 protections, making it suitable for washdowns, dust, and harsh environments typical of chemical plants, offshore facilities, and mining sites, with robust safety and compliance assurances.
The 8000 lumen output at 59 W delivers bright, uniform illumination with a high efficacy of 135 lm/W, improving visibility for inspections, maintenance, and safety-critical tasks. The high PF (>0.94) ensures efficient power conversion and lower electrical stress, while the wide distribution minimizes shadows and reduces the need for additional fixtures in large industrial spaces.
Yes. Copper-free aluminum construction with a natural finish provides corrosion resistance, while IP66/IP67 ratings protect against water and dust ingress. The 39 inch length and 1.50 inch pole mount simplify retrofits on existing poles, and the robust NEMA 4X rating supports outdoor and marine installations. Plan for appropriate mounting height and orientation to maximize the wide distribution and ensure cable routing remains compliant with local electrical codes.
