FAQs

The MLLA2-UNV1-S903D-P-M2 is designed for flush ceiling mounting with 3/4" entries and a 2 ft form factor. It supports universal voltage (120-277 VAC) and 127/250 VDC, enabling a single fixture family to cover most sites. For retrofit projects, verify conduit and mounting hardware compatibility, ensure the location is permitted for Class I, Division 2/Zone 2 installations, and follow the Eaton installation sheets for proper wiring and grounding.
Key specs include 4000 lumens with a 132 lm/W efficacy, 30W power consumption, PF > 0.92, and a cool white LED color. The fixture operates at 50/60 Hz with a wide optical distribution (Wide), and uses a diffused polycarbonate lens. This combination delivers uniform illumination across industrial spaces while minimizing energy costs and heat generation.
Yes. The luminaire is certified for Hazardous/Classified Locations and carries NEC/CEC compliance. It lists Class I, Division 2 and Zone 2 ratings, alongside NEMA 4X protection and IP66/IP67 ingress protection, making it appropriate for petrochemical, oil & gas, and similar hazardous environments requiring robust lighting and safety standards.
The MLLA2-UNV1-S903D-P-M2 uses copper-free aluminum with a durable epoxy finish, reducing corrosion risks in wash-down areas. Its LED technology delivers long life with low heat output and high PF, lowering replacement frequency and energy-related costs. The 2 ft length and flush-mount design simplify installation and alignment, improving uptime and reducing maintenance labor over time.
Refer to NEC/CEC standards for hazardous locations, IP66/IP67 protection for ingress control, and NEMA 4X for exterior and corrosion resistance.
