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.

Black Anodized LED Profiles Channels that stop reading as a fitting

A black channel is a different design decision, not a colour option. On a dark ceiling, dark joinery or a black reveal, an anodised black body reads as a shadow gap instead of a line of metal. 10 profiles in this finish, strip widths 10–25 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.

The line stops reading as a fitting

A black anodised surface takes the bright edge off the extrusion. Against a dark background the channel reads as a shadow rather than an object.

It is chosen where a silver body would fight the design

On dark joinery, stone or a black window reveal, the black version is the one that stays out of the composition.

The finish is the only difference in how you specify it

Strip width, mounting and outer dimensions are chosen exactly as for the rest of the range — you are picking a finish, not a different system.

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 Check the finish against the surface it sits on

Black on black reads as a shadow. Black on a light surface reads as a deliberate line — both are useful, but they are different details.

02 Then the strip width

This group accepts 10–25 mm strip.

03 Then the mounting

All four mounting types appear in this group: recessed, surface, suspended and corner.

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.

Is the finish anodising or paint?

The bodies in this group are black-finished and come from the black range; the exact surface treatment for a given model is stated on its datasheet, which is linked from every card.

Will the black fade outdoors?

That depends on the surface treatment rather than the colour, and exterior duty is a different question from finish. For outside work start from the waterproof and outdoor range.

Can I mix black and silver in one run?

Physically yes, but the join will read. Where a run continues from one to the other, that junction is worth drawing before you order.

Are the sections the same as the silver range?

The sections are chosen the same way — by strip width, mounting and outer dimensions. Not every silver section has a black counterpart, so check the list on this page.

Do you also do other colours?

The finish field on each model states what is available. Painting is offered alongside anodising on much of the range.

Anodised or painted — which should I pick?

They behave differently at the edges and at the joints. What a given model carries is stated on its datasheet, which is linked from every card, so check that before you commit the run.

Will the black read the same along the whole run?

Do not assume it. Finishing is done in batches, so on a long run it is worth confirming that the lengths come from one batch. Tell us the total length and we will check it against the order.
