What is an LED ceiling profile?

An LED ceiling profile is an extruded aluminium channel that carries an LED strip and fixes into a ceiling — either into a pocket formed by a drop or shadow gap, or recessed into the plasterboard itself. The channel holds the strip, takes a diffuser, and sets the line the light reads as.

What is the difference between a ceiling profile and a cove profile?

Both are aluminium channels. A cove channel hides in a pocket above the sight line and throws its output across the ceiling, so the strip is never visible. A recessed ceiling profile sits in the board itself, so the diffuser stays in view as a defined line. The choice is about whether you want the source hidden or expressed.

How do I pick the right strip width?

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 7 mm to 63 mm. Filter by the strip you already buy, then check the outer height against the pocket you can build.

Can these profiles be used in a plasterboard or false ceiling?

Most of this range is recessed, and the majority of those are plaster-in bodies: 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.

Do the profiles come with a diffuser and end caps?

Diffuser and accessory options differ by model. What each channel ships with is listed on its specification sheet — use the PDF button on any card to check before you specify.

What if nothing in the list matches my ceiling detail?

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.

Under-Cabinet LED Profiles Channels for worktops, shelves and joinery

Light on the work surface, not in the eye. An under-cabinet channel hides under the carcass or inside a rebate, so what lands on the worktop is a wash and not a fitting. This range runs 6–21 mm strip over outer heights from 8.3 mm.

01 / WHY

Three decisions decide whether this detail works

The channel is only part of it. What the run looks like in service depends on what it is fixed into, the section you choose and how the output is aimed.

Shallow enough to disappear

Outer heights in this range start at 8.3 mm, so the body clears a shallow reveal under a carcass or behind a door line.

A wash, not a row of dots

The diffuser is what turns the strip into even light on the surface. Without it you are looking at individual LEDs.

Cut to the cabinet, not the other way round

Bodies come in 4 m lengths and are cut to the run. Corner and surface versions cover the returns where a straight run ends.

Four of the decisions that come up first, each answered from the live range above — by outer height, by the strip you already buy, and by how the body has to be fixed.

How to narrow this range down to one body

Three numbers decide it, in this order. Every figure below is this group, not the whole catalogue.

01 Measure the reveal first

Depth from the underside of the carcass to the door line is the number that limits you. Outer heights here run 8.3–30 mm.

02 Then check the strip width

This range accepts 6–21 mm strip. The channel has to take what you already buy.

03 Then decide the fixing

Screw-fixed, clip-on and corner bodies are all in this group — the fixing decides whether the strip can be serviced later.

07 / ORDER

What to send us, and what you get back

Most ceiling details are settled on the drawing, not on a phone call.

STEP 01 Send the ceiling detail
A section sketch, a photo of the reveal, or just the pocket depth and the strip you plan to use.
STEP 02 We match it to a section
We check the tooling we already run before proposing anything new — most details map onto an existing profile.
STEP 03 You get the drawing
The dimension drawing for the matched model, with W, H and the strip width it accepts, so you can check the cut-out.
STEP 04 Sample, then order
Cut lengths and finishing are confirmed against the drawing before anything goes to production.

08 / FAQ

What buyers ask before specifying this group

The questions that come up most often before a run is signed off.

Will it show when the cabinet door is open?

That is decided by outer height, not by the model. The bodies here run from 8.3 mm upwards; anything that stays below the door line disappears when the door is closed.

Can the same body be used under a shelf or in a wardrobe?

Yes. The bodies are used for shelf and wardrobe lines as well; the only constraint is the reveal you can form and the strip you are fitting.

Does it need a diffuser?

A diffuser is what makes the output read as a wash over the worktop. Diffuser and accessory options differ by model — the drawing on each card shows what the body takes.

What length does it come in?

4 m as standard, cut to the run. Custom lengths on request.

What if nothing matches the reveal I have?

Send the depth you are working with. We hold the tooling for the range, so it is usually a question of which existing section drops in.

Can the strip be replaced later if it fails?

Yes — the cover comes out and a new strip goes in, so the cabinet does not have to come apart. How it comes out differs by body: on some it is a push fit, on others it slides out of the end. The section drawing on each model shows which.

Retrofit, or does the cabinet have to be made for it?

Either. On a finished cabinet the body screws or clips to the underside and the cable runs along the back. Where the cabinet is being built, the recessed bodies in this group can be set into a rebate instead, so only the opening shows.
