What is a Plaster-In LED Profile?
A plaster-in LED profile (sometimes called recessed or trimless) is a clever aluminium housing designed to sit flush within your wall or ceiling. Once plastered over, only the glowing LED strip remains visible—no bulky fittings, just a soft, clean line of light, perfect for modern and minimalist interiors.
Planning Your Install: When and Where
The ideal time to install plaster-in profiles is during new builds or renovations—before plastering begins. Think of them as architectural features, not just decorative lights. Use them to define walkways, illuminate ceiling beams, or create ambient backlighting on a kitchen backsplash or TV unit.
How to Install: Practical Steps
Start by marking your profile path. Cut your profile to fit, insert into drywall or ceiling board, screw securely, and feed your LED strip through. Once wired and tested, plaster over the wings of the profile until seamless. Once it’s smooth, paint and admire the magic!
Why Choose LED For This?
LED strips are highly energy-efficient, flexible, long-lasting, and produce virtually no heat—making them perfect for embedded setups. At Future Light, our CCT and COB strip lights deliver gorgeous smooth illumination with no visible dots, ideal for recessed profile installs.
Always test all electrics before plastering—you don’t want to go fishing inside a ceiling later!
