Quick decision summary: If you need a flush ceiling or wall line, choose a recessed plaster-in profile. If you want a visible trim under kitchen cabinets or shelving, a slim surface-mount channel works best. Corner profiles sit in 90-degree junctions for cove or display lighting. Floor profiles carry a walk-over rated diffuser for step and threshold lighting. Not sure which one? Call 01952 370028 and the ATOM LED technical team will match the profile to your project.

Who this is for: Electrical contractors fitting out kitchens, bathrooms, and commercial spaces. Interior designers specifying cove, pelmet, and display lighting. DIY installers who want a professional finish on COB or SMD strip runs. Shopfitters and hospitality fit-out teams needing consistent linear lighting across long runs.

Who this is NOT for: If you are looking for neon flex mounting channels, those are a different product category with a different cross-section. If you need a flexible silicone extrusion for curved surfaces, see our silicone profile range instead. Rigid aluminium strip profiles are designed for straight runs and fixed angles only.

Common buying mistakes to avoid:

• Ordering a profile narrower than the strip: A 12 mm-wide internal channel will not accept a 14 mm COB strip — always check the internal width against your strip specification before ordering.
• Ignoring depth in shallow ceiling voids: Recessed profiles range from 7 mm to 35 mm deep, and a deep profile will not fit a 10 mm ceiling recess without additional routing.
• Skipping the diffuser entirely: Without a diffuser, individual LED dots or COB segments are visible to the eye, especially on SMD strip, and the finished result looks unfinished rather than professional.
• Using the wrong diffuser for the task: A clear diffuser preserves maximum brightness but shows every LED chip; a frosted diffuser softens the light and hides hot spots but reduces output by approximately 10–15 percent.
• Forgetting thermal paste on high-wattage strip: Any strip above 14 W/m benefits from a thin layer of thermal compound between the strip PCB and the aluminium channel base to improve heat transfer.

What does an LED strip profile actually do?

An LED strip profile is a rigid aluminium channel that houses LED strip, protects it from physical damage, spreads heat away from the LEDs, and supports a diffuser that blends individual light points into a smooth, continuous line. In 2026, profiles are standard practice on any professional-grade LED strip installation in the UK, not an optional extra.

Strip lighting mounted directly onto a surface with only its self-adhesive backing will work short term, but it creates three problems that a profile solves permanently. First, the 3M VHB adhesive on most strip tape is rated for clean, smooth surfaces at moderate temperatures — once the strip warms up above approximately 50 degrees Celsius under sustained use, adhesion weakens and the strip begins to peel. An aluminium channel holds the strip mechanically regardless of temperature. Second, aluminium acts as a passive heatsink. LED junction temperatures above the manufacturer's rated maximum reduce light output and accelerate lumen depreciation. A 2026 study of COB strip lifespan data shows that strips mounted on aluminium profiles typically maintain over 90 percent of their initial output at the L70 threshold, compared to approximately 70–80 percent for strips on plasterboard alone. Third, the diffuser transforms a row of dots into an even wash that looks finished rather than temporary.

• Physical protection: The channel walls shield the strip from accidental contact, cleaning cloths, and minor impacts in kitchens and commercial environments.
• Heat management: 6063-T5 aluminium alloy — the standard extrusion grade used in most UK LED profiles — has a thermal conductivity of approximately 200 W/m-K, which draws heat away from the LED junction efficiently.
• Light diffusion: A frosted polycarbonate or PMMA diffuser typically reduces visible hot spots by over 95 percent on COB strip and completely eliminates dot visibility on most SMD strip.
• Aesthetic integration: Profiles can be recessed, surface-mounted, corner-mounted, or suspended to suit the architecture rather than forcing the lighting to sit awkwardly on the surface.

Which LED strip profile type do you need?

The five main LED strip profile types are surface-mount, recessed (plaster-in or routed), corner (45-degree), floor/walk-over, and pendant/suspended. Each type is designed for a specific mounting condition, and choosing the correct one depends on where the profile will sit, whether the installation is new-build or retrofit, and the visual effect you want to achieve.

Profile type	Typical depth	Mounting method	Best application	Diffuser position
Surface-mount	7–12 mm	Screw or adhesive	Under-cabinet, shelving, display cases	Top-facing flush
Recessed (routed)	12–20 mm	Routed channel in timber or plasterboard	Ceilings, walls, joinery, fitted furniture	Flush with surface
Recessed (plaster-in)	20–35 mm	Fixed into plasterboard with flanges	New-build ceiling coves, wall washes	Flush with plaster finish
Corner (45-degree)	15–18 mm per side	Screw into internal 90-degree junction	Cove lighting, display cabinets, kickboard junctions	Angled 45 degrees
Floor / walk-over	10–15 mm	Recessed into floor or threshold	Hallways, stair nosing, commercial thresholds	Top-facing, impact-rated
Pendant / suspended	20–50 mm	Wire or rod suspension from ceiling	Office desks, retail counters, kitchen islands	Downward or dual-emission

For most residential kitchen under-cabinet projects in 2026, a slim surface-mount profile between 7 mm and 9 mm deep is the standard choice. It sits flat against the underside of wall units and is barely visible from normal standing height. For ceiling coves in new-build properties, a plaster-in recessed channel with flanges allows the plasterer to finish the ceiling right up to the diffuser edge, creating an invisible light slot that appears to glow from within the ceiling itself.

• Retrofit tip: Surface-mount profiles are the fastest to install because they screw or adhesive-mount directly onto existing surfaces with no routing or chasing required.
• New-build tip: Recessed plaster-in profiles should be fixed before the first coat of plaster, with the diffuser removed and masked during plastering to keep the channel clear.
• Corner-mount note: The 45-degree angle throws light across the ceiling or down a wall at an angle that a flat surface profile cannot replicate — ideal for creating indirect ambient lighting in bedrooms and living rooms.

How do you choose the right profile width for your strip?

Measure the total width of your LED strip — including any Waterproof coating or sleeving — and select a profile with an internal channel width at least 1 mm wider. Most standard COB strips are 8 mm, 10 mm, or 12 mm wide. RGBW COB strip and some high-density SMD strips are 12–14 mm wide. The ATOM LED range includes profiles with internal widths from 10 mm up to 20 mm to cover every strip type in stock.

The most frequent sizing error on profile orders is assuming that the external profile width equals the internal channel width. A profile that measures 17 mm across the outside may only have a 12 mm internal channel once you subtract the wall thickness on each side. Always check the internal dimension, not the external.

Strip type	Typical strip width	Minimum internal channel width	Recommended ATOM LED profile width
24 V single-colour COB	8 mm	9 mm	10 mm internal
48 V single-colour COB	10 mm	11 mm	12 mm internal
RGBW COB strip	12–14 mm	14 mm	15 mm internal
Addressable digital RGB COB	10–12 mm	12 mm	12 mm internal
High-density SMD 2835 (double row)	12–15 mm	15 mm	17 mm internal
IP67 sleeved strip	Original width + 2–3 mm	Strip width + 3 mm	Check with ATOM LED team

If you are installing IP67-rated outdoor COB strip inside a profile for additional mechanical protection, remember that the silicone sleeve adds approximately 1.5 mm to each side of the strip. A strip that measures 10 mm bare will measure approximately 13 mm with its IP67 sleeve, which means you need a minimum 14 mm internal channel.

• Tight fit warning: Forcing strip into a channel that is too narrow risks damaging the solder connections and can create intermittent faults that are extremely difficult to diagnose after installation.
• Too-loose fit note: A channel that is significantly wider than the strip is not harmful electrically, but the strip may shift sideways and create an uneven light line if not secured with thermal adhesive tape or additional clips.

---

What profile depth and mounting style suit each application?

Profile depth determines how far the channel sits below or protrudes from the mounting surface. Shallow surface profiles at 7–9 mm are almost invisible under cabinets. Medium-depth recessed profiles at 12–20 mm sit flush within routed timber or plasterboard channels. Deep plaster-in profiles at 25–35 mm accommodate higher-wattage strips that need more heatsinking mass and are designed for new-build or major renovation projects where ceiling voids allow the depth.

In 2026, the trend in UK residential and commercial lighting design is toward fully recessed profiles that create a "line of light" effect with no visible hardware. This requires planning the recess before the surface is finished. For retrofit projects where cutting into ceilings or walls is not practical, a slim surface-mount profile remains the most efficient solution and can be painted to match the mounting surface after installation.

• Under-cabinet (surface): Use a 7–9 mm deep profile mounted with screws or adhesive to the underside of kitchen wall units, set back approximately 30 mm from the front edge to keep the profile hidden from the standing eye line.
• Ceiling cove (recessed): Route a channel into a timber pelmet or bulkhead before finishing, or use a plaster-in profile with flanges that allow the plasterboard to butt up against the channel edges.
• Display shelving (surface or recessed): Recessed into the underside of each shelf for invisible lighting, or surface-mounted at the rear of the shelf for indirect upward wash onto the displayed items.
• Staircase nosing (recessed floor): A walk-over rated floor profile recessed into the front edge of each tread provides both safety marking and ambient stairwell lighting in one fitting.
• Kitchen island pendant: A suspended pendant profile hung on adjustable steel cables from the ceiling gives direct task lighting over a work surface, replacing traditional pendant fixtures with a continuous light line.

Does an LED strip channel improve heat dissipation?

Yes — mounting LED strip inside an aluminium profile typically reduces LED junction temperature by 10 to 20 degrees Celsius compared to direct mounting on timber, plasterboard, or MDF. Lower junction temperatures extend LED lifespan, maintain higher lumen output over time, and reduce the risk of adhesive failure. For any strip rated above 10 W/m, ATOM LED recommends profile mounting as standard practice, not as an upgrade.

The thermal performance of an LED strip profile depends on three factors: the mass of the aluminium extrusion, the surface area exposed to air, and the quality of the thermal bond between the strip PCB and the channel base. A heavier profile with thicker walls dissipates more heat. A profile mounted with airflow around it (such as a suspended pendant) dissipates more than one sealed into a tight ceiling recess with no ventilation.

• Strip below 10 W/m: A standard-weight surface profile provides adequate cooling for most residential runs at this wattage, and no additional thermal compound is usually needed.
• Strip at 10–20 W/m: Use a medium-weight profile and apply a thin, even layer of thermal paste or thermal adhesive tape between the strip PCB and the aluminium base for reliable thermal transfer.
• Strip above 20 W/m: Use the deepest available profile with the greatest aluminium mass, apply thermal compound, and ensure the mounting location allows at least partial airflow around the profile body.
• Strips must never be powered while coiled on a reel: Even with a profile, a coiled strip concentrates heat at the centre of the coil and can reach temperatures that damage the PCB, the adhesive, and — in extreme cases — present a fire risk.
• Bare metal mounting warning: If mounting a profile directly onto a conductive metal surface (such as a steel shelf bracket or aluminium structural member), ensure the LED strip PCB does not make direct electrical contact with the mounting surface — use the profile's insulating diffuser and end caps to maintain isolation.

On high-output commercial projects — retail display, hospitality bars, architectural cove lighting — the profile is not optional. It is part of the electrical specification, and most UK lighting designers in 2026 include the profile as a line item in their tender documentation rather than leaving it as a contractor decision.

Which diffuser should you pick — frosted, clear, or opal?

For most 2026 LED strip installations, a frosted (also called semi-diffused or semi-opal) diffuser is the default choice because it eliminates visible LED dots and hot spots while reducing light output by only approximately 10–15 percent. A clear diffuser preserves maximum brightness but leaves individual LEDs visible, making it suitable only for applications where the profile is hidden from direct view. A full opal diffuser provides the smoothest light line but reduces output by approximately 20–30 percent.

COB LED strip — which ATOM LED stocks across 24 V and 48 V dot-free ranges — already produces a far more uniform light line than traditional SMD strip because the phosphor layer is continuous rather than segmented into individual chips. When paired with a frosted diffuser in a profile, COB strip produces a light line that is virtually indistinguishable from high-end commercial fluorescent strip at a fraction of the energy consumption.

• Frosted / semi-opal diffuser: Best all-round choice for kitchens, bathrooms, coves, display lighting, and any location where the profile is visible to occupants.
• Clear diffuser: Use where maximum lumen output is critical and the profile is hidden inside a pelmet, coffer, or behind a fascia board where occupants cannot see the strip directly.
• Full opal diffuser: Use where the smoothest possible light line is required and a 20–30 percent brightness reduction is acceptable — typically high-end residential or boutique retail.
• No diffuser (open channel): Only appropriate for indirect lighting where the strip faces a wall or ceiling and no one can see the LED surface — for example, inside a wall-wash cove where the light bounces off a surface before entering the room.

All ATOM LED profiles ship with at least one diffuser option included in the box. If your project requires a different diffuser type, contact operations@atomled.co.uk or call 01952 370028 and the technical team can advise on compatible diffuser swaps across the range.

How do you install an LED strip profile step by step?

Installing an LED strip profile takes approximately 30–60 minutes per 2.5-metre length for an experienced installer. The process covers surface preparation, profile fixing, strip mounting, wiring, diffuser fitting, and end cap installation. Following these steps in order avoids the most common errors that lead to uneven light lines, poor thermal contact, and premature strip failure.

1. Step 1 — Measure and plan the run: Measure the total length required and determine how many profile lengths you need, allowing for any mitred joints at corners. Mark the mounting position on the surface with a pencil line, checking for level with a spirit level over the full run length. For recessed profiles, mark the routing depth and width at both ends and at 500 mm intervals along the run.
2. Step 2 — Cut the profile to length: Use a fine-tooth hacksaw or a mitre saw with a non-ferrous metal blade to cut the aluminium profile to your measured length. File or deburr the cut end to remove any sharp edges that could damage the strip during insertion. Cut the diffuser separately with the same tool — do not attempt to cut the diffuser while it is clipped into the profile, as it will crack.
3. Step 3 — Fix the profile to the surface: For surface-mount profiles, use the supplied mounting clips or drill through the profile base at 300–400 mm intervals and fix with appropriate screws for the substrate. For recessed profiles, route the channel with a router or Dremel to the required width and depth, then press-fit or screw the profile into the channel. Check alignment before final fixing.
4. Step 4 — Apply thermal compound (high-wattage strip only): For strip rated above 14 W/m, apply a thin continuous line of thermal paste along the centre of the profile base before inserting the strip. This fills microscopic air gaps between the strip PCB and the aluminium, improving thermal conductivity by up to 40 percent compared to the self-adhesive tape alone.
5. Step 5 — Mount the LED strip into the profile: Peel the 3M backing from the strip and press it firmly onto the profile base, starting at one end and working along the length. Apply even, firm pressure — do not stretch the strip. Ensure the strip sits centrally in the channel with equal clearance on both sides. Do not power the strip until it is fully mounted and straight.
6. Step 6 — Wire the strip to the driver: Connect the strip to the appropriate LED driver using soldered connections or push-fit COB strip connectors. Use parallel wiring for runs over 5 metres to minimise voltage drop. Confirm polarity before powering on. Test the full run at full brightness for at least 5 minutes before fitting the diffuser.
7. Step 7 — Fit the diffuser and end caps: Snap or slide the diffuser into the profile channels along the full length. Press end caps onto both open ends — use the supplied end caps with cable exit holes at the feed end, and solid end caps at the opposite end. The diffuser should click firmly into place without bowing or lifting.

For projects requiring more than 20 metres of continuous single-colour strip, ATOM LED's 48 V COB range allows a single feed up to 30 m, which means fewer driver locations and fewer wiring terminations. That reduces installation time and the number of potential fault points. Call the ATOM LED technical team on 01952 370028 to discuss long-run profile and strip combinations for your project.

What are the most common LED strip profile mistakes?

The five most common mistakes are selecting a profile that is too narrow for the strip, failing to account for diffuser light loss in the lumen calculation, mounting profiles without checking level over the full run, skipping thermal compound on high-wattage strips, and cutting the diffuser while it is clipped into the profile. Each of these is avoidable with 60 seconds of preparation before installation begins.

• Mistake 1 — Wrong internal width: Measuring the external profile dimension instead of the internal channel width is the single most common return reason on profile orders in the UK. Always check the product datasheet for internal width before ordering.
• Mistake 2 — Ignoring diffuser light loss: If a lighting plan specifies 800 lumens per metre at the work surface and you fit a frosted diffuser that reduces output by 12 percent, you are delivering approximately 704 lumens per metre. Factor the diffuser loss into your specification at the design stage, not after installation.
• Mistake 3 — Not checking level: A 2.5-metre profile fitted 3 mm higher at one end than the other creates a visible slope on the light line that draws the eye. Use a spirit level and packing shims on uneven surfaces to ensure the profile runs dead level or follows the intended architectural line precisely.
• Mistake 4 — Skipping thermal compound: On strip rated at 14 W/m and above, the self-adhesive backing alone does not provide sufficient thermal transfer to the aluminium. A thin layer of thermal paste between the PCB and the profile base can reduce junction temperature by 8–12 degrees Celsius.
• Mistake 5 — Cutting diffuser inside the profile: Polycarbonate diffusers crack under saw pressure if they are constrained. Always remove the diffuser, cut it separately, and re-fit after cutting. Use a fine-tooth blade and support the diffuser on both sides of the cut line.

A sixth error specific to 2026 projects: ordering incompatible end caps. Many profile manufacturers sell end caps and diffusers as separate SKUs, and cross-brand compatibility is not guaranteed. ATOM LED profiles ship with matched end caps and diffusers in the box to eliminate this problem entirely.

How do surface-mount profiles compare to recessed channels?

Surface-mount profiles fix onto the face of an existing surface with screws or adhesive and protrude by 7–12 mm. Recessed channels sit inside a routed or pre-formed groove so that the diffuser finishes flush with the surrounding surface. Surface profiles are faster to install and suit retrofit projects. Recessed profiles produce a cleaner, more integrated finish and are standard on new-build and high-specification fit-outs in the UK.

Factor	Surface-mount profile	Recessed profile
Installation time (per 2.5 m)	15–25 minutes	30–60 minutes
Surface preparation	Clean and level only	Routing or chasing required
Visible profile body	Yes — profile edges visible	No — only diffuser face visible
Retrofit suitability	Excellent — no structural modification	Limited — needs accessible substrate for routing
New-build suitability	Adequate	Preferred — planned into construction sequence
Typical applications	Under-cabinet, shelving, display, signage	Ceiling coves, wall washes, joinery, stair treads
Diffuser finish line	Raised above surface	Flush with surface
Cost per metre (profile only)	Lower	Higher (plus routing labour)

On many projects, both types are used in different areas. A 2026 residential kitchen might use surface-mount profiles under the wall cabinets (retrofit, fast, hidden by the cabinet overhang) and recessed plaster-in profiles in the ceiling above the island (new ceiling, plastered flush, invisible hardware). The ATOM LED range covers both mounting types across all channel widths, so the strip and diffuser specifications remain consistent regardless of how the profile is mounted.

Can you use LED strip profiles outdoors or in bathrooms?

Standard aluminium LED strip profiles are not inherently Waterproof, but they can be used in damp or outdoor locations when combined with IP-rated strip, sealed end caps, and — where required — a silicone gasket between the diffuser and the channel body. For fully exposed outdoor installations or bathroom wet zones under BS7671, use IP67 or IP68 rated strip inside the profile and seal every joint and end cap with neutral-cure silicone to prevent moisture ingress.

Note on IP ratings: IP65-rated strip provides surface-splash protection only and is not considered suitable for permanent outdoor use in UK weather conditions or for use in bathroom zones 1 and 2 under BS7671. For outdoor garden paths, decking edges, or building facades, use a minimum of IP67-rated products or IP68-rated products if the installation will be exposed to standing water or continuous submersion.

• Bathroom Zone 2 (beyond 600 mm from shower/bath): IP67 strip inside a sealed profile with silicone gaskets on end caps is typically acceptable under BS7671, provided the circuit is on a 30 mA RCD.
• Bathroom Zone 1 (directly above bath/shower to 2.25 m height): IP67 strip minimum, fully sealed profile, and the driver must be located outside the bathroom zones.
• Outdoor — sheltered (under eaves, canopy): IP67 strip in a sealed profile provides adequate protection where direct rainfall is blocked but humidity and condensation are present.
• Outdoor — fully exposed: IP67 or IP68 strip is required, and all electrical connections must use IP-rated junction boxes. Consider LED neon flex as an alternative for fully exposed runs, as the entire unit is factory-sealed.
• Decking and floor-level outdoor: Walk-over floor profiles with sealed diffusers and IP67 strip are used for decking edge and step lighting, but the profile must be installed with drainage clearance to prevent standing water pooling inside the channel.

For any outdoor or bathroom profile project, contact the ATOM LED technical team on 01952 370028 or email operations@atomled.co.uk before ordering. The team will confirm the correct combination of profile, strip IP rating, driver placement, and sealing method for your specific installation in 2026.

LED strip profile FAQ

1. What is the difference between an LED strip profile and an LED strip channel?

• No functional difference: "Profile," "channel," "extrusion," and "housing" are interchangeable terms used across the UK LED industry for the same product — an aluminium enclosure that holds LED strip and supports a diffuser.
• Naming varies by supplier: Some UK suppliers use "channel" for shallow surface-mount products and "profile" for deeper recessed extrusions, but there is no formal industry standard for this distinction in 2026.

2. How long are LED strip profiles?

• Standard lengths: Most profiles are supplied in 1 m, 1.5 m, or 2.5 m lengths, depending on the manufacturer and profile type.
• Joining longer runs: For runs longer than the profile length, use inline joining connectors or butt the profiles end-to-end with a straight coupler to maintain a continuous light line.

3. Can I cut an LED strip profile to a custom length?

• Yes: Aluminium profiles cut easily with a fine-tooth hacksaw or mitre saw with a non-ferrous blade.
• Cut the diffuser separately: Remove the diffuser before cutting the aluminium channel, then cut the diffuser to match and re-fit after deburring both cut ends.

4. Do I need thermal paste between the strip and the profile?

• Below 14 W/m: The strip's self-adhesive backing provides adequate thermal transfer for most residential applications at this power level.
• Above 14 W/m: Apply a thin layer of thermal compound to the profile base before mounting the strip — this improves heat transfer and extends LED lifespan.

5. What material are LED strip profiles made from?

• Body: 6063-T5 anodised aluminium alloy is the industry standard for LED strip profiles in 2026 — it combines good thermal conductivity (approximately 200 W/m-K) with corrosion resistance and a clean surface finish.
• Diffuser: Polycarbonate (PC) or polymethyl methacrylate (PMMA), depending on the profile model — both are UV-stable and impact-resistant.

6. Will a frosted diffuser reduce brightness noticeably?

• Typical reduction: A frosted diffuser reduces light output by approximately 10–15 percent compared to a clear diffuser.
• In practice: Most installations compensate by specifying strip with 10–15 percent higher lumen output, or the slight reduction is imperceptible against the improved visual uniformity.

7. Can I paint an LED strip profile to match my ceiling or wall?

• Yes: Anodised aluminium accepts spray paint well after a light scuff with fine abrasive (240-grit) to key the surface.
• Mask the diffuser channel: Use painter's tape inside the diffuser slot before painting to prevent paint buildup that could prevent the diffuser from clipping in correctly.

8. How do I join two LED strip profiles end to end?

• Inline connector: A small aluminium or plastic coupler slides inside both profile ends to align them and create a continuous channel.
• Alignment is critical: Any step or gap between joined profiles creates a visible break in the light line, so dry-fit and check alignment before fixing permanently.

9. What profile do I need for COB strip lights?

• Standard COB strip (8–10 mm wide): Any profile with a 10 mm or wider internal channel will accept standard COB strip from the ATOM LED range.
• RGBW COB strip (12–14 mm wide): Use a profile with a minimum 14 mm internal channel — check the ATOM LED product listing for confirmed compatibility.

10. Are LED strip profiles fireproof?

• Aluminium is non-combustible: 6063-T5 aluminium does not burn and has a melting point of approximately 615 degrees Celsius, far above any temperature an LED strip will produce.
• Diffusers are self-extinguishing: Polycarbonate diffusers are rated UL94 V-2 or better, meaning they will stop burning within seconds of the ignition source being removed.

11. Can I use LED strip profiles for indirect ceiling lighting?

• Yes — this is one of the most common applications: A recessed or surface-mount profile fitted inside a ceiling pelmet or shadow gap, aimed upward, bounces light off the ceiling to create soft ambient illumination without any visible hardware.
• Profile position: Set the profile 50–100 mm from the wall to allow the light to spread across the ceiling before hitting the wall surface.

12. Do ATOM LED profiles work with other brands of strip?

• Compatibility is based on strip width: If the strip measures within the internal channel width of the profile, it will physically fit regardless of brand.
• Best results with matched products: ATOM LED profiles are tested with ATOM LED strip for optimal fit, thermal contact, and diffuser clearance — using third-party strip may introduce fit tolerances that affect the light line quality.

13. How do I choose between a corner profile and a surface profile for cove lighting?

• Corner profile (45-degree): Mounts into the 90-degree junction between wall and ceiling or wall and cabinet, throwing light diagonally across the ceiling or down the wall at an angle that creates even wash.
• Surface profile: Mounts flat on either the wall or the ceiling surface inside a pelmet or coffer, directing light straight up or straight out. Choose based on where you can physically mount the profile and which light direction suits the room geometry.

14. What drivers work with LED strip in profiles?

• Single-colour strip: Use a constant voltage driver matched to the strip voltage (12 V, 24 V, or 48 V) and rated to at least 120 percent of the total strip wattage to allow headroom.
• RGB and RGBW strip: Use a non-dimmable constant voltage driver paired with a dedicated RGB or RGBW controller — never a dimmable driver, which causes flicker, colour shift, and premature failure on multi-channel strip.
• Dimmable single-colour: Use a TRIAC dimmable LED driver with a trailing-edge dimmer for smooth, flicker-free dimming.

15. How many profiles do I need for a 6-metre kitchen run?

• Standard calculation: If the profile is supplied in 2.5 m lengths, a 6 m run requires three lengths (2.5 m + 2.5 m + 1 m cut from a third length), plus two inline joining connectors.
• Order spare: On runs requiring multiple cuts and joins, ordering one extra length is prudent in case of a cutting error or a profile that arrives with minor transit damage.

16. Can I recess an LED strip profile into a concrete floor?

• Yes, with preparation: Chase a channel into the concrete using a diamond blade, set the floor profile into construction adhesive or mortar, and ensure the diffuser sits flush with or 1 mm below the finished floor level to prevent tripping edges.
• Use walk-over rated profiles only: Standard surface-mount profiles are not designed for foot traffic loading — use a profile specifically rated for floor or walk-over applications with a reinforced diffuser.
