High luminous output and efficiency translate to measurable energy savings. The MLLAW4-UNV1-S903-M2 delivers 8000 lumens at 59 W, achieving 135 lumens per watt and a power factor greater than 0.94. For plants operating around the clock, this performance reduces annual energy costs while maintaining bright, uniform illumination across work zones. In hazardous locations, improved efficiency also reduces heat generation, easing cooling loads and strengthening overall plant thermal management. This combination supports faster return on investment and better lighting quality for operators in assembly, maintenance, and quality control areas. Rugged enclosure and certifications drive compliance and uptime. IP66/IP67 ingress protection and a NEMA 4X rated enclosure protect against water, dust, and corrosive exposure in chemical processing and offshore facilities. Copper-free aluminum housing plus a polycarbonate lens resist corrosion and impact, shrinking replacement cycles. The 3/4 entry capability simplifies cable routing in limited spaces, while the flush ceiling mounting accelerates retrofits and reduces installation time for new builds. Wide optical distribution ensures consistent lighting with fewer fixtures, cutting both material and labor costs on large-scale projects. Flexible power and mounting options enhance project versatility. The fixture supports 120-277 Vac and 127/250 Vdc, enabling seamless integration with diverse electrical systems and control schemes. Its 4 ft length, 39 in housing, and warm white color suit industrial aesthetics and worker comfort. The sturdy finish and copper-free aluminum construction withstand demanding environments. When paired with Eaton's installation resources and catalogs, procurement teams gain confidence through standardized components and verified performance data across hazardous location deployments. Operational reliability and service life. The Champ MLLA is built for long life in harsh environments, with low maintenance requirements and consistent lumen output. By combining high efficacy with robust protection, the fixture supports reduced maintenance intervals and minimized outage risk, contributing to safer operations and better asset uptime across facilities such as petrochemical plants, mining operations, and water treatment facilities.
