This 45mm inner width LED channel S5418mm is a great choice for flush-mount drywall and plaster projects, giving you that polished, trimless look. While the exterior measures 54mm wide and 18mm high, the S5418 surprisingly offers a generous 45.2mm internal width. This makes it a great house for substantial LED strips like the Philips Hue Lightstrip, and it works just as well with high-density LED tapes. Plus, its shallow design makes installation a breeze, even in tight ceiling cavities.
Installation is both secure and simple thanks to our unique recessed buckle system, which locks the profile firmly into the wall or ceiling. It’s the best choice for architectural projects that need a clean, steady light source and a seamless, built-in look.
