a standard recessed body?<\/summary>\n          <p>Trimless means no flange is left showing once the plaster goes on, so the opening is the only thing you\n          see. A standard recessed body keeps a flange that covers the cut edge. Both are in this range &mdash; the\n          installation tag on each card says which one that model is.<\/p>\n        <\/details>\n        <details>\n          <summary>Can the strip be replaced later if it fails?<\/summary>\n          <p>Yes &mdash; the diffuser comes out and a new strip goes in, so the ceiling does not have to be opened up.\n          How it comes out differs by body: on some it is a push fit, on others it slides from the end. The section\n          drawing on each model shows which.<\/p>\n        <\/details>\n        <details open>\n          <summary>What is an LED ceiling profile?<\/summary>\n          <p>It is an extruded aluminium channel that carries an LED strip and fixes into a ceiling \u2014 either into a pocket formed by a drop or shadow gap, or recessed into the plasterboard itself. The channel holds the strip and takes a diffuser; the pocket and the section decide how the light reads once it is up.<\/p>\n        <\/details>\n        <details>\n          <summary>What is the difference between a ceiling profile and a cove profile?<\/summary>\n          <p>Both are aluminium channels. A <a href=\"\/de\/led-aluminum-profile\/recessed\/\" style=\"color:var(--cl-amber)\" target=\"_blank\">vertieft<\/a> ceiling profile sits in the board itself, so the diffuser stays in view as a defined line. A cove channel hides in a pocket above the sight line and throws its output across the ceiling, so the strip is never visible. The choice is whether you want the source expressed or hidden.<\/p>\n        <\/details>\n        <details>\n          <summary>How do I pick the right strip width?<\/summary>\n          <p>The channel is tooled for a band of strip widths, and that number is the first hard limit. In this range the accepted strip width runs from <b id=\"clFaqStrip\">7 to 63<\/b> mm. Filter by the strip you already buy, then check the outer height against the pocket you can build.<\/p>\n        <\/details>\n        <details>\n          <summary>Can these profiles be used in a plasterboard or false ceiling?<\/summary>\n          <p>Most of this range is recessed, and the majority of those are plaster-in bodies \u2014 the flange is buried in the board and only the opening remains visible. The drawing for each model gives the outer dimensions the cut-out has to clear.<\/p>\n        <\/details>\n        <details>\n          <summary>Do the profiles come with a diffuser and end caps?<\/summary>\n          <p>Diffuser and accessory options differ by model. What each channel ships with is listed on its specification sheet \u2014 use the PDF button on any card above to check before you specify.<\/p>\n        <\/details>\n        <details>\n          <summary>What if nothing here matches my ceiling detail?<\/summary>\n          <p>Send us the section you are working to. We hold the tooling for the range, so matching an unusual reveal or strip width is usually a question of which existing section it maps onto.
