High lumen output paired with impressive efficiency (8000 lm at 135 lm/W) translates into fewer fixtures required for large areas, delivering immediate energy savings and reduced maintenance visits in demanding facilities. This directly supports lower total cost of ownership while meeting stringent illumination standards for safety-critical environments. The fixture’s IP66/IP67 and NEMA 4X ratings provide robust protection against dust, water jets, and corrosive exposure, which means longer intervals between replacements in chemical plants and offshore settings. With a universal 120-277 VAC and 127/250 VDC input and 50/60 Hz operation, it integrates smoothly with existing power systems and control schemes, minimizing wiring changes and commissioning time. The copper-free aluminum housing, diffused polycarbonate lens, and 4 ft form factor offer a compact, durable solution that reduces mounting complexity and supports flush-ceiling installations. Optional emergency-backup configurations (IF 1946 series) enable continued operation during outages, enhancing plant resiliency and safety compliance. Overall, the Champ MLLA line balances rugged construction with efficient, dependable lighting for hazardous locations.
