Model: DL-CL2138
Overview
The DENO DL-CL2138 21x38mm outdoor contour linear lighting is a robust solution designed for architectural and landscape illumination. Featuring a 24V DC input, it delivers up to 10W/m with a high CRI >90 and 1 SDCM binning for consistent color. Its IP67 rating ensures durability in outdoor environments. Constructed with 2oz copper FPCB and 99.99% gold wire bonding, this fixture is suitable for facade accents, pathway lighting, and other exterior linear applications requiring precise and reliable illumination.
Description
Constructed from 6063 aluminum alloy profiles, this outdoor contour linear lighting fixture delivers superior thermal dissipation to effectively suppress luminous decay. Anodized or powder-coated aluminum surfaces provide exceptional resistance against salt spray, acid rain, and corrosion across demanding coastal outdoor environments. Precision injection-molded optical structures deliver uniform, glare-free illumination with seamless connection and dimmable control for wholesale project supply. Integrated with IP67 waterproof connectors, continuous fixtures up to 3m quickly interconnect to form scalable architectural lighting contour systems. Ideal for commercial facades and curtain walls, the system highlights geometric building lines with continuous illumination and zero dark spots.
