Description
DL-CL2138 | 21x38mm Outdoor Contour Linear Lighting | IP67 Constructed from high thermal conductivity 6063 aluminum alloy profiles, the product delivers outstanding mechanical strength and superior heat dissipation performance. It effectively lowers the operating junction temperature of LED chips and greatly suppresses luminous decay of light sources. The surface of aluminum is treated with anodizing or outdoor electrostatic powder coating technology, which has strong resistance to salt spray, corrosion and acid rain, making it easy to cope with coastal or high humidity environments. Compared with traditional extruded PC tubes, injection molding technology can achieve more precise wall thickness control and complex internal tooth optical structure, with uniform and soft light output, seamless connection between lamps, achieving no dark areas or spots, and eliminating glare problems from the source. Equipped with IP67 waterproof connectors, the system enables fast installation and flexible expansion. Multiple fixtures can be linked together to form large-scale architectural outlining systems while reducing installation time on site. Suitable for outlining the edges or ridges of curtain walls in office buildings and high-end residences. The ultimate uniformity of its light output linearity can perfectly reproduce the geometric line design of architects, presenting a high-end architectural night vision.
