Feature → Business Impact → Application: The Champ MLLA LED fixture is built with a diffused polycarbonate lens and copper-free aluminum housing, delivering high durability and reduced corrosion in demanding environments; this translates to longer service life and lower replacement costs for critical lighting. The wide optical distribution and 4 ft form factor provide broad coverage with fewer fixtures, reducing installation time and material costs on large industrial rigs. With a 59W power draw and 8000 lumens, efficiency is boosted to about 135 lm/W, supporting lower energy bills and cooler operation in hot plant spaces, while maintaining a PF > 0.94 for compliant power quality. The ceiling/swivel mounting and 3/4" entry capabilities simplify retrofits and new installs in constrained ceilings, enabling flexible layouts. The device meets NEC/CEC standards and hazardous-location classifications (Class I Zone 2, Division 2; Class II Division 1; Class III) with IP66/IP67 and NEMA 4X protection, ensuring reliable performance in oil, gas, chemical, and mining environments. This combination of rugged build, optical efficiency, and installation versatility supports measurable reductions in maintenance rounds, energy usage, and downtime during plant outages.
