The DL4 Down Light is a precision-machined aluminum or brass LED fixture engineered for performance, flexibility, and long-term serviceability across a wide range of architectural applications. Available with either a 120–277V integral driver COB LED or a remote driver option, it features modular, industry-standard components that simplify maintenance, allow field replacement of optics, COB, and driver, and support future upgrades. Offered in round and square profiles with multiple mounting, cap, and stem configurations, it is built for durability with a thick-walled cap, optimized high-temperature silicone O-ring placement, and a molded silicone lead seal to prevent moisture intrusion. Certified for wet or dry locations and approved for ceiling-mount installation, the DL4 is ideal for interior and exterior residential, commercial, retail, and hospitality environments.
