The S3518 flangeless recessed LED channel is a good choice for many LED strips, offering a generous 21mm inner width for a professional look. Designed to fit perfectly into ceilings or walls, it delivers a clean, trimless finish that can elevate any space.
Thanks to its recessed buckle mounting system, the profile stays perfectly flush with the plasterboard. This smart design completely hides the aluminum channel inside the groove, leaving nothing but bright, pure light that feels like a natural part of the architecture.
Crafted from high-quality 6063-T5 anodized aluminum, the S3518 ensures excellent heat dissipation to help your LEDs last longer. It’s the best way to have perfect architectural lighting in modern houses, businesses, stores, and hotels where a clean look is important.
