Long-life LED with 8000 lumens at 59 W delivers high efficiency and reduced maintenance, translating to lower operating costs and fewer downtime events in 24/7 production lines. This translates to significant energy savings (about 135 lm/W) and dependable illumination across large work zones like warehouses, refineries, and assembly bays. Hazardous-location compliance (NEC/CEC) and ratings for Class I Division 2, Zone 2, Class II Division 1, and Class III, coupled with IP67/IP66 and NEMA 4X protection, deliver peace of mind for installations in wet, dusty, or chemically aggressive environments. The integral emergency battery backup ensures critical light during power outages, supporting safe evacuation and minimal disruption to operations. Copper-free aluminum housing provides superior corrosion resistance, while a natural aluminum finish and diffused polycarbonate lens optimize longevity without compromising light quality. The 4 ft form factor with 3/4" entries and ceiling/swivel mounting simplifies retrofits and new installs alike, reducing installation time and enabling flexible positioning across varied ceilings and enclosures. Designed for 120-277 Vac and 127/250 Vdc with 50/60 Hz operation, the MLLA4CS-UNV1-S903D-EM1-M2 supports diverse electrical infrastructures, enabling rapid deployment and scalable lighting upgrades in demanding environments.
