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.

Mini LED Profiles The smallest channels in the range

When the reveal is 12 mm, the channel has already chosen itself. Seven bodies with an outer width of 10–12.3 mm, for the places where nothing larger will go.

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.

Sized by the reveal, not by preference

Outer width is 10–12.3 mm. That is the whole point of the group: it fits where a standard body physically cannot.

Narrow strip, short runs

Six to ten millimetre strip. These are detail lines — an edge, a shelf, a recess — not the main lighting of a room.

Four different fixings in seven bodies

Surface, recessed, suspended and corner all appear here, so the small size does not lock you into one detail.

Pick the constraint you actually have

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 gap you actually have

Outer width 10–12.3 mm is the hard limit. Measure the reveal, not the drawing.

02 Then the strip

This range takes 6–10 mm strip only.

03 Then how it is held

At this size the fixing detail is the part that decides whether it can be serviced, so check it before you specify.

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.

How small is small?

Outer width from 10 mm and outer height from 8.3 mm. Below that you are looking at a different class of product.

Will a mini body take a standard strip?

No — this group accepts 6–10 mm strip. If your strip is wider, look at the standard range instead.

Is it bright enough to light a room?

These are detail bodies. Output is set by the strip you put in them and the run length, not by the channel; where a room needs general light, a larger section is the right answer.

What are they normally used for?

Shelf edges, cabinet returns, narrow recesses and architectural shadow lines — anywhere the detail is small enough that a standard body would show.

What if even this is too big?

Send the dimension you have. At that point it is a tooling question rather than a catalogue question, and we will say so.

What strip width will a body this small take?

Six to ten millimetres only. A wider strip will not go in, so check the strip before the profile.

How does it differ from the ultra-slim range?

Different constraint. Mini is about outer width — for a narrow reveal. Ultra-slim is about outer height — for a shallow depth. Some details are limited by one and not the other.
