Feature → Business Impact → Application: The DLLA4-UNV1-S903-WH-M2 delivers 8000 lumens at 59W with a high 135 lm/W efficacy and cool-white color, providing bright, efficient illumination that lowers operating costs and improves visibility in hazardous environments such as chemical plants and refineries. This results in reduced maintenance cycles and safer worker conditions by eliminating frequent bulb replacements and ensuring consistent light levels across work zones. The IP66/IP67 ratings and NEMA 4X enclosure protect the fixture from dust, water ingress, and corrosion, delivering longer service life in washdown areas and outdoor installations, thereby lowering total cost of ownership. The 4 ft form factor with 3/4" entries and flush ceiling mounting simplifies retrofit projects and minimizes installation time while maintaining a clean ceiling profile for compliant facilities. Wide optical distribution reduces shadows, enabling accurate process inspection and safer material handling in warehouses and production lines. The universal voltage capability (120-277 VAC, 127/250 VDC) and 50/60 Hz operation support diverse electrical environments, ensuring compatibility with existing power systems and reducing the need for separate drivers or transformers.
