FAQs

For hazardous locations, plan flush-ceiling mounting with 2 ft length and 3/4 inch entry points. Ensure supply is within 120-277 VAC or 127/250 VDC, and verify compliance with NEC/CEC for Class I Division 2, Zone 2 and related hazardous classifications. Use proper wiring methods, seal connections against dust and moisture, and follow UL/CSA installation sheets to minimize downtime and maximize safety.
The MLLA2-UNV1-S903-EM1-M2 delivers 4000 lumens at 132 lm/W from a 30 W input. It operates at 50/60 Hz with a voltage range of 120-277 VAC or 127/250 VDC. The optical distribution is Wide, with a polycarbonate lens, and the fixture uses copper-free aluminum in a natural aluminum finish, providing robust environmental resistance.
Yes, there are UL and certification resources specific to marine use for Champ MLLA fixtures. While the core hazardous-location ratings apply on land, the marine certification documents indicate suitability for offshore and maritime environments when installed per guidance. Always consult the marine-certified sheets and UL/CSA documentation when deploying in saltwater or corrosive atmospheres.
Key advantages include flush ceiling mounting for a clean look, 2 ft form factor for compact layouts, and 3/4 inch entry points that simplify conduit connections. The universal voltage (120-277 VAC or 127/250 VDC) and 50/60 Hz support make retrofits straightforward, reducing downtime and enabling rapid deployment across mixed electrical systems in industrial facilities.
The fixture combines energy efficiency (4000 lm at 132 lm/W) with an integral emergency battery, reducing energy costs and eliminating the need for separate emergency units. Its robust IP67/IP66 protection, NEMA 4X sealing, and hazardous-location compliance minimize maintenance, extend service life in harsh environments, and support safer, compliant operations with faster installation.
