4545 Corner Ceiling LED Profile
The Effortless Cove — 45°×45° Aluminium Corner Channel That Turns Any Ceiling-Wall Junction Into Architectural Lighting
What Is the 4545 Corner LED Profile?
The 4545 Corner Ceiling LED Profile is a 45×45mm right-angle aluminium extrusion that sits in the 90° junction between a ceiling and wall. Its defining feature is the 45° angled diffuser face — oriented to project diffused LED light at a 45° angle downward and into the room. The LED strip is completely concealed inside the corner channel; only the soft, uniform glow from the angled face is visible.
4545 Profile vs. Built Plaster Cove
Why the 4545 corner profile is the smarter specification for most cove lighting projects.
✅ Nucleo 4545 Corner Profile
- Fix in corner and insert strip — done in under an hour
- No plastering, no formwork, no drying time
- Perfect alignment every time — aluminium is precise
- Remove and reuse if space is reconfigured
- Consistent diffuser quality along the full run
- Same visual result as a built cove from 3m+ away

🏗️ Built Plaster / GRC Cove
- Requires carpenter + plasterer + painter
- 7–14 days from start to LED installation ready
- Quality varies with tradesperson skill
- Permanent — expensive to change later
- Variable gap and edge quality along run
- Visually superior at very close viewing distances
- Limited colour/finish options without paint
- Complex to retrofit CCT or dimming upgrades
- Higher labour cost — specialist trades required
Lighting Effects with the 4545 Profile
Six distinct visual outcomes from one profile — all from the same 45° corner installation.
Ceiling Border Wash
Warm white COB strip in the 4545 profile washes the upper wall below the ceiling line with a soft gradient — the signature of premium Indian false-ceiling interior design.
Sunrise / Sunset Glow
RGB or CCT tuneable strip in the profile — dial from warm amber (sunset) to cool blue-white (morning). The 45° angle spreads the colour wash beautifully down the wall.
Ceiling Plane Definition
In rooms with flat ceilings, the 4545 profile creates a visual "float" effect — the ceiling appears to hover above the wall because the light line marks its boundary definitively.
Feature Wall Accent
Install only on the wall behind a bed, sofa, or TV unit — a single-wall ceiling border creates a focal frame that draws the eye and defines the room's centrepiece.
Full Perimeter Ambient
Run the 4545 profile along all four walls of a room — the ceiling perimeter glows uniformly, eliminating harsh overhead direct lighting for a deeply comfortable ambient environment.
Office / Retail Border
In commercial spaces with suspended ceilings, the 4545 profile on the ceiling border visually raises the perceived height of the room and adds architectural quality without major works.
Three Finish Options
Choose the finish that disappears into your ceiling corner — or makes a deliberate design statement.
Silver Anodised
Brushed aluminium appearance. Suits contemporary and industrial interiors. Visible against both light and dark walls — works as a deliberate metallic detail.
Black Anodised
Most popular for premium interiors. Disappears against dark feature walls and dark false ceilings — only the light line is seen, not the hardware.
White Powder Coat
Blends seamlessly with white plasterboard ceilings and white walls — appears as a subtle shadow gap detail until illuminated. Ideal for residential and hospitality spaces.
Why Choose the Nucleo 4545 Profile?
Install in Hours
No building works, no trades coordination, no drying time. Fix the profile in the corner, insert the strip, snap on the diffuser — a full room perimeter is done in a single working day.
Built-In Heatsink
6063 aluminium body conducts heat away from the LED strip through the ceiling and wall contact surfaces — extending strip lifespan to 50,000+ hours in the corner installation.
Cut to Any Length
Standard 2-metre pieces cut to any shorter length with an aluminium mitre saw. Mitre-cut at 45° for perfect internal and external room corner joints — no visible gap at corners.
45° Optimised Beam
The angled face is specifically positioned to project light at the ideal angle for wall washing — light spreads evenly from ceiling to mid-wall height for maximum visual impact.
COB Compatible
12mm channel accepts COB LED strip — the seamless glow on the 45° diffuser face looks dramatically better than individual-chip SMD strip at any viewing distance.
Full Accessories
Matching end caps, internal corner joiners, external corner joiners, and mounting clips — every accessory needed for a professional, mitre-free corner finish is available.
Technical Features
📐 45° × 45° Equal Legs
Both legs equal at 45mm — perfect symmetry for a 90° corner. Neither the ceiling nor wall leg dominates visually. Balanced, clean installation geometry.
🔲 12mm Channel Width
Accepts 8mm, 10mm, and 12mm LED strips. LED strip presses flat against the aluminium channel base for maximum thermal contact — heatsinking effect from two surfaces simultaneously.
🔗 Corner Joiners
Dedicated 90° internal corner joiner and 90° external corner joiner accessories — maintain perfect profile alignment at room corners without visible butt joints or gaps.
🎚️ Diffuser Options
Opal (maximum dot-concealment), frosted (semi-diffused, more lumen output), and clear (maximum output, no diffusion). All snap into the angled face channel.
📏 2m Standard Length
Two-metre pieces cut with any aluminium-rated fine-tooth saw. Internal and external 45° mitre cuts achievable on a standard mitre saw for perfect room corner joins.
🏗️ Plasterboard Integration
Profile installed before final skim — plasterboard can be filled up to the profile edge for a flush, built-in appearance with no visible screw heads or fixing clips.

Installation Guide
📐 Standard Corner Install
- Mark the profile line around the room perimeter using a laser level set to the desired height below the ceiling. The profile sits in the corner — the mark indicates where the bottom edge of the wall leg will sit, confirming the profile position before fixing.
- Cut the profile to the required wall lengths. For room corners: cut each piece at 45° mitre angles so adjacent pieces join cleanly — a standard mitre saw with an aluminium-rated fine-tooth blade achieves this easily. Deburr all cut ends with a fine file.
- Dry-fit all pieces including corner joints before applying adhesive. Verify each piece sits flush in the corner with the ceiling and wall legs in full contact. For plasterboard ceilings, check no bow in the plasterboard pushes the profile away from the corner.
- Apply a continuous bead of construction adhesive (CT1 or Stixall) to the back surface of both the ceiling leg and the wall leg. Press the profile firmly into the corner — the adhesive should squeeze out slightly at both edges. Wipe excess immediately.
- For larger profiles or high-ceiling installations, add countersunk 3mm × 30mm screws through the ceiling leg at 400mm intervals as temporary support while adhesive cures. Once cured (24 hours), the adhesive alone provides permanent fixing strength.
- Insert COB or SMD LED strip into the channel. Route the strip connection cable along the profile back toward the driver position. Snap the diffuser into the angled face channel. Connect to driver, power on, and verify uniform brightness along the full perimeter.
🏗️ False Ceiling Integration Install
- For new false ceiling builds: fix the 4545 profile to the main wall at the intended ceiling border line before plasterboard is fitted. The profile acts as the ceiling edge trim — the plasterboard meets the profile's ceiling leg.
- Mark the profile height on the wall all around the room. Fix profile to wall only at this stage using appropriate wall fixings — Rawlbolts for masonry, drywall anchors for stud walls — at 400mm intervals through the wall leg.
- Install the plasterboard false ceiling up to the profile's ceiling leg. The plasterboard edge butts against or slightly under the ceiling leg — the profile conceals the raw plasterboard edge and creates the cove reveal simultaneously.
- Skim coat the ceiling up to the profile face. For a flush-integrated look, the plaster skim can cover the outer face of the ceiling leg — leaving only the angled diffuser face visible. Fill the join between plaster and profile with flexible decorator's caulk.
- Once all plastering and painting is complete, insert the LED strip from one end. Route the cable to the driver location (typically in the ceiling void above the false ceiling). Connect and test before installing the diffuser cover.
- Snap the diffuser into the angled face as the final step — after all wet trades are complete. This protects the diffuser from plaster splash and paint overspray, and allows easy access to the strip for any changes before handover.
📐 The Corner That Changes the Room
Every ceiling has four corners. In most rooms, those corners are the most ignored surfaces — a line where two planes meet and nothing happens. The 4545 profile changes that. It takes the most overlooked detail in a room and makes it the source of the room's most compelling light. The ceiling border glows softly, the wall washes gently upward, and the room acquires a quality it has never had before — depth, warmth, and the sense that it was designed by someone who understood light.
The Nucleo 4545 is used by interior designers who understand that indirect lighting is not an upgrade — it is the foundation of how a space feels. And it is used by homeowners who discovered what a corner can do when it has something to say. Available in silver, black, and white. Cut to any length. Compatible with any LED strip.
