The knife-edge aluminum LED channels are designed to be integrated into 1/2-inch plasterboards at the ceiling-to-wall junction, providing a clean and minimalist finish. They feature an inclined lighting design that conceals the LED strips, with the light reflected upwards along the perimeter of the ceiling, providing a soft, indirect wall wash lighting effect. Ideal for living rooms, hotels, lobbies, corridors, and upscale retail interiors. The indirect light channels are made from 6063-T5 aluminum material and feature a powder-coated surface treatment, providing anti-oxidation resistance and a longer lifespan. The standard lengths are 1 m and 2 m, and allow for easy cutting to any desired length. Two types of diffused covers are available: PC diffused covers and PC semi-clear covers. They are made of imported-brand material, anti-yellowing, and with perfect light distribution. The inner width is 18.9 mm, allowing for a maximum width of light strips of 18 mm. We recommend using our 15mm high-power COB strip lights as the light source to create continuous linear lighting, with no visible light dots or dark areas. The 90°, 90° vertical, and 180° connectors are sold separately and can be used for angled or straight connections. The end caps are included.
