Quick decision — which 48V COB strip do you need?

• Hotel corridor or retail run over 20 metres: 48V warm white 3000K IP20 — mount inside a continuous aluminium profile for one unbroken line across the full length.
• Garden perimeter or building facade: 48V IP67 in your preferred colour temperature — rated for permanent UK outdoor exposure including rain, frost, and UV.
• Open-plan office or conference space: 48V natural white 4000K IP20 — colour-accurate task lighting that runs wall to wall from a single feed.
• Warehouse or workshop ceiling cove: 48V cool white 6000K IP20 — maximum output over a 30-metre bay without brightness loss.
• Residential feature lighting over 10 metres: 48V warm white 2700K IP20 — where a single unbroken line matters more than anything else in the room.

Who 48V COB strip is for: Electrical contractors and lighting specifiers fitting hotel corridors, retail aisles, office perimeters, restaurant cove runs, and architectural facade outlines where a single unbroken 30-metre line of light must hold consistent brightness from end to end. Homeowners with large open-plan spaces, stairwell runs, or garden perimeters that exceed 20 metres. Anyone who needs to simplify a long installation by eliminating mid-run power injection.

Who 48V COB strip is NOT for: If your total run is under 10 metres, 24V single colour COB strip costs less per metre and uses more widely available drivers. If you need RGB colour-changing effects, browse our RGB COB strip — 48V COB is single colour white only. If the strip will be fully submerged in a pond or fountain, you need IP68 from our IP68 range rather than IP67.

Common buying mistakes to avoid in 2026:

• Using a 24V driver on 48V strip: The strip will not illuminate. 48V COB strip requires a dedicated 48V constant-voltage LED driver — standard 24V drivers are incompatible regardless of wattage rating.
• Oversizing without headroom: A 30-metre run at 10W/m draws 300W total. Choose a 48V driver rated at a minimum of 360W — approximately 20 percent headroom helps prevent thermal stress and extends driver lifespan.
• Choosing IP65 for outdoor installation: IP65 covers surface splashes only and does not withstand sustained UK rainfall, frost-thaw cycling, or ground moisture. IP67 is the minimum for permanent outdoor 48V COB strip under BS7671 guidance.
• Running strip while still coiled on the reel: Concentrated heat destroys adhesive and risks fire. Always uncoil, mount to a heat-sinking surface or aluminium profile, and only then connect power.
• Mounting directly onto bare uninsulated metal: Exposed copper traces on the PCB short-circuit against conductive surfaces. Mount inside an anodised aluminium profile or apply an insulating barrier first.

Why choose 48V COB LED strip over 24V for long runs?

At the same wattage per metre, 48V draws half the current of 24V. Lower current means less energy lost as heat in the copper traces and supply cables, which translates directly into longer maximum runs, thinner cabling, and consistent brightness from the first metre to the thirtieth. For any installation exceeding 15–20 metres, 48V is the engineering solution that typically eliminates the need for mid-run power injection and the extra drivers, wiring, and access points that come with it.

The physics is direct. Voltage drop is proportional to current multiplied by resistance. At 10W per metre, a 48V strip draws approximately 0.21A per metre compared with 0.42A per metre for a 24V strip of equivalent wattage. Over 30 metres, that halved current keeps voltage drop within acceptable limits from a single end feed — something 24V simply cannot achieve without parallel injection at multiple points along the run.

• Fewer components to fail: A 30-metre 48V run uses one driver and one power connection. A 24V run of the same length typically needs two or three injection points plus additional cabling — each one a potential failure point and a maintenance headache in commercial settings.
• Thinner supply cables: Lower current allows thinner gauge cabling between the driver and the strip, reducing material costs and simplifying cable routing through ceiling voids, wall cavities, and profile channels.
• SELV classification when correctly installed: 48V DC falls within the SELV voltage threshold under BS7671 (120V DC ripple-free maximum), provided it is supplied from a suitably isolated, safety-rated driver. This means reduced shock risk under dry conditions — though not zero risk, particularly in wet environments.
• Simplified commercial specification: For architects and lighting designers specifying hotel corridors, retail perimeters, or office cove lighting in 2026, 48V reduces the number of drivers, connection points, and maintenance access hatches on the drawing, which reduces both installation cost and long-term service complexity.

How far does 48V COB strip run from a single power point?

Every 48V COB LED strip in the UK LED Lights range runs up to 30 metres of continuous, dot-free illumination from one single-end power connection. The constant-current IC design built into each strip actively regulates current delivery to every LED segment across the full 30-metre length, maintaining consistent brightness and colour temperature from the first centimetre to the last.

Thirty metres is the tested and verified maximum for single-end power at 10W per metre with acceptable voltage drop. This covers the vast majority of commercial and residential projects — a standard UK hotel corridor is typically 25–30 metres per floor section, a retail aisle runs 15–25 metres, and even large open-plan living spaces rarely exceed 20 metres on a single wall run.

• 30-metre reel supplied as standard: Each 48V COB strip ships on a full 30-metre reel, ready to cut to your exact length at 50mm intervals. No joining, no soldering mid-run — one continuous piece.
• Cuttable every 50mm: Marked cut points every 5 centimetres let you trim to the precise measurement your project demands, whether that is 4.7 metres for a kitchen island or 28.3 metres for a corridor.
• Dual-end feeding for runs beyond 30m: If your project requires more than 30 metres in a single unbroken line, powering from both ends extends the total run — each end drives up to 30 metres, giving a theoretical maximum of 60 metres. Contact our technical team on 01952 370008 for guidance on dual-feed wiring for projects of this scale.

What colour temperatures are available in 48V COB strip?

UK LED Lights stocks 48V COB strip in four single-colour white options: warm white 2700K for the most relaxed residential feel, warm white 3000K for hospitality and living spaces, natural white 4000K for task-focused commercial environments, and cool white 6000K for workshops, warehouses, and industrial spaces. All four achieve CRI 90+ for accurate colour rendering under the light.

Colour temperature is measured in Kelvin and describes the appearance of white light. Lower numbers produce warmer, amber-toned light. Higher numbers produce cooler, bluer light. Getting this choice right is one of the most important decisions in any lighting project — the wrong colour temperature makes a space feel clinical, flat, or uncomfortably yellow regardless of how well the strip itself performs.

• 2700K warm white: The warmest option in the range. Matches the tone of a traditional incandescent bulb. Ideal for residential bedrooms, living rooms, and boutique hospitality settings where a cosy, relaxed atmosphere is the goal. First introduced to the UK LED Lights 48V range in early 2026.
• 3000K warm white: The standard choice for kitchens, dining areas, hotel corridors, and restaurant cove lighting. Warm but not overly yellow — strikes the balance most UK interior designers specify for living spaces in 2026.
• 4000K natural white: Neutral, balanced light that neither warms nor cools the appearance of surfaces beneath it. The professional choice for office perimeters, retail displays, dental surgeries, and kitchen task lighting where accurate colour perception matters.
• 6000K cool white: High-output, daylight-equivalent white. Best suited to garages, workshops, warehouse cove lighting, and commercial spaces where maximum visibility is the priority over ambience.

Colour Temperature	Appearance	Best Applications	IP20 Available	IP67 Available
2700K Warm White	Soft amber tone	Bedrooms, living rooms, boutique hospitality	Yes	Yes
3000K Warm White	Warm but balanced	Kitchens, hotel corridors, restaurants, dining	Yes	Yes
4000K Natural White	Neutral daylight	Offices, retail, task areas, clinical spaces	Yes	Yes
6000K Cool White	Bright crisp white	Garages, workshops, warehouses, industrial	Yes	Yes

Which IP rating — IP20 indoor or IP67 outdoor?

Choose IP20 for any dry interior installation — kitchens (mounted inside a profile above the splash zone), living rooms, office ceilings, hotel corridors, and retail displays. Choose IP67 for any location exposed to rain, ground moisture, frost, condensation, or direct water contact — garden perimeters, building facades, covered patios, car park soffits, and bathroom zones 1 and 2 under BS7671.

The difference is physical construction. IP20 strip is an open-face flexible PCB with an adhesive backing — lightweight, thin (approximately 2mm), and easy to press into aluminium profiles. IP67 strip is encased in a protective silicone sleeve that seals the LEDs and circuitry against temporary water immersion, adding roughly 2mm to the total depth and widening the strip to approximately 12mm.

• IP20 for dry interiors: Thinner profile, easier to fit into narrow aluminium channels, and slightly brighter output due to no silicone light diffusion. Ideal for commercial fit-outs where moisture is not a concern — 8mm or 10mm PCB width fits most standard UK profiles.
• IP67 for outdoor and wet locations: Rated for temporary immersion under BS7671. Withstands continuous UK rainfall, frost-thaw cycling, and UV exposure. The silicone sleeve provides mechanical protection against physical contact during maintenance. IP67 is the correct minimum rating for any permanent outdoor 48V strip installation in the UK.
• IP65 is not sufficient for UK outdoor use: IP65 covers surface splash only. Sustained rainfall, pooling water on horizontal surfaces, and moisture ingress through freeze-thaw cycles will eventually penetrate IP65 encapsulation. We stock IP67 and IP68 specifically because IP65 fails in real UK conditions.
• If your project needs full submersion: IP67 48V strip is not rated for continuous underwater operation. For ponds, fountains, or water features, browse our IP68 submersible range or call 01952 370008 for guidance.

What driver and wattage does 48V COB strip need?

Every 48V COB LED strip requires a dedicated 48V constant-voltage LED driver. The driver must be rated at a minimum of 20 percent above the total strip wattage to prevent thermal stress and ensure reliable long-term operation. For a full 30-metre reel at 10W per metre, that means a minimum 360W 48V driver — and UK LED Lights stocks matched drivers tested specifically with our 48V COB range.

A 48V driver is a specialist component. Standard 12V and 24V LED drivers are not compatible and will either fail to power the strip or produce no light at all. The driver must output regulated 48V DC constant voltage with sufficient wattage headroom for the total connected strip length. Here is how to calculate your requirement:

1. Measure your total strip length in metres.
2. Multiply by 10W (the consumption per metre of every 48V COB strip in our range).
3. Add 20 percent headroom to the result.
4. Select the next available driver wattage at or above that figure.

• 5-metre run: 50W strip load — minimum 60W driver.
• 10-metre run: 100W strip load — minimum 120W driver.
• 20-metre run: 200W strip load — minimum 240W driver.
• 30-metre run: 300W strip load — minimum 360W driver.

Browse our 48V LED driver range or call 01952 370008 for help selecting the correct driver for your project. Our technical team will confirm compatibility, advise on dimming options, and recommend the correct IP-rated driver for your installation environment.

How do you dim 48V COB strip without flickering?

48V COB LED strip dims smoothly from 100 percent down to approximately 1 percent using PWM (pulse width modulation), 0–10V, DALI, or DMX control signals sent through a compatible 48V dimming interface. The strip itself is inherently dimmable — the key is pairing it with the correct 48V controller and, where applicable, a trailing-edge mains dimmer on the input side of the driver.

Flickering in dimmable LED installations almost always originates from one of three causes: an incompatible dimmer type, an undersized driver, or an incorrect control protocol. All three are avoidable with the right component selection.

• PWM dimming: The most common method for 48V strip. A PWM controller switches the strip on and off thousands of times per second — varying the ratio of on-time to off-time changes perceived brightness. Flicker-free at any level.
• 0–10V dimming: Analogue signal from a wall-mounted 0–10V controller adjusts driver output. Widely used in commercial fit-outs and compatible with building management systems. Simple wiring — two additional low-voltage control wires.
• DALI dimming: Digital Addressable Lighting Interface — the commercial and architectural standard in 2026. Allows individual channel control, scene programming, and integration with smart building platforms including Lutron, Loxone, Control4, Casambi, and Crestron.
• DMX dimming: Used in hospitality, entertainment, and retail display applications where precise scene control and timed sequences are required.
• Trailing-edge mains dimmer: If the 48V driver has a triac-dimmable input, a trailing-edge wall dimmer provides simple on-wall brightness control. Leading-edge dimmers frequently cause flicker with LED drivers — replacing a leading-edge with trailing-edge costs approximately fifteen pounds and typically resolves the problem in most installations.

How do you install 48V COB LED strip step by step?

Installing 48V COB LED strip follows the same core process as any low-voltage LED strip — measure, mount, wire, test — but with two critical differences: you must use a dedicated 48V driver, and the 30-metre maximum run means a single feed point covers most full-length installations without mid-run injection. The entire process takes an experienced electrician approximately 2–3 hours for a standard 20–30 metre corridor or perimeter run.

1. Step 1 — Survey and measure the installation route: Walk the full run with a tape measure. Record every straight section, every corner, and every transition. Identify where the 48V driver will be located — ideally within 3 metres of the strip start point to minimise supply cable voltage drop. Note any obstacles: junction boxes, ventilation grilles, structural beams, and fire stops that the strip or cable route must navigate around.
2. Step 2 — Calculate wattage and select the 48V driver: Multiply total strip length by 10W per metre. Add 20 percent headroom. Select a driver at or above that figure from our 48V driver range. For a 25-metre hotel corridor in 2026, that calculation is 250W plus 50W headroom, requiring a minimum 300W 48V driver.
3. Step 3 — Mount the aluminium profile along the full run: Fix the profile to the mounting surface using screws at 300mm centres. Use corner connectors at 90-degree transitions and joiners for inline profile extensions. The profile serves as both a heat sink and a mechanical mount — it is not optional for commercial installations where the strip runs continuously for 10 metres or more.
4. Step 4 — Cut the strip to length and press into the profile: Uncoil the reel fully on a clean, dry surface — never power strip while coiled. Measure the exact length needed and cut at the nearest 50mm marked cut point using sharp scissors. Peel the adhesive backing and press the strip firmly into the base of the aluminium profile, working from one end to the other without stretching or bunching.
5. Step 5 — Wire the strip to the 48V driver: Connect the strip positive and negative leads to the 48V output terminals on the driver using appropriately rated cable. If using a dimming controller, wire it between the driver output and the strip input. Double-check polarity — reversed connections will not damage the strip but it will not illuminate.
6. Step 6 — Connect the driver to the mains supply: The 48V driver input connects to 230V AC mains. This must be carried out by a qualified electrician in accordance with BS7671 and Part P of the Building Regulations. Ensure the driver is located in a ventilated, accessible position for future maintenance — not buried inside a sealed ceiling void.
7. Step 7 — Test before closing up: Power on and verify even brightness from end to end. Dim up and down through the full range to check for flicker. Inspect every section for adhesive lifting, misalignment, or visible damage. Only after a successful full-power test should you clip the profile diffuser cover into place and close any ceiling hatches or access panels.

Where does 48V COB strip perform best — project by project?

48V COB strip is engineered for long, uninterrupted runs where consistent brightness matters more than anything else — hotel corridors, retail aisles, commercial office perimeters, architectural cove features, restaurant ceiling details, and large residential open-plan spaces. Any project where the total run exceeds 15–20 metres benefits from 48V over 24V in terms of reduced component count, simpler wiring, and lower long-term maintenance cost.

• Hotel corridors and hospitality: A 25-metre corridor lit with 48V warm white 3000K COB strip inside a recessed aluminium profile delivers a single continuous line of warm light from lift lobby to fire exit — one driver, one feed, no visible joints. Multiply across 10 floors and the reduction in drivers and wiring adds up to measurable savings on a 2026 fit-out budget.
• Retail perimeter and display lighting: Run 48V natural white 4000K around the full perimeter of a shop floor — 30 metres of CRI 90+ light that renders product colours accurately without a single brightness dip. Visual merchandising teams specify this configuration for flagship stores where lighting consistency defines the brand experience.
• Office cove and ceiling perimeter: Open-plan offices in 2026 increasingly specify indirect cove lighting as the primary ambient source, with task lights at each desk. A 48V strip in a ceiling cove helps eliminate the patchwork of separate 24V sections and injection points that complicate maintenance access in suspended ceilings.
• Restaurant and bar ceiling features: Run warm white 2700K through a continuous architectural detail above a dining area. The dot-free output of COB technology reflects cleanly off polished surfaces, glassware, and table settings — visible dot patterns from SMD strip destroy the effect at close dining distances.
• Garden perimeters and landscape borders: A 30-metre IP67 run around a garden boundary, along a driveway edge, or outlining a patio terrace — powered from a single weatherproof 48V driver mounted in a garage or utility cupboard.
• Stairwell and multi-storey lighting: Continuous runs down stairwells and along landings where mid-point access for power injection is impractical. A single 48V driver at the top or bottom feeds the full vertical run.
• Kitchen island and large residential runs: Open-plan kitchen-diners with 12–15 metre perimeter runs benefit from 48V even at residential scale — one feed point, zero brightness variation, paired with a triac-dimmable driver and trailing-edge wall dimmer for full brightness control.

Frequently Asked Questions — 48V COB LED Strip

• Is 48V COB strip safe to install in a home? Yes. 48V DC falls within the SELV voltage threshold under BS7671 (120V DC ripple-free maximum), provided it is supplied from a suitably isolated, safety-rated driver. SELV classification means significantly reduced shock risk under dry conditions — not zero risk. The mains-side connection to the 48V driver must be carried out by a qualified electrician.
• Can I use my existing 24V LED driver with 48V strip? No. A 24V driver will not power 48V strip — the voltage is insufficient and the strip will not illuminate. You need a dedicated 48V constant-voltage driver rated at a minimum of 20 percent above your total strip wattage.
• Does 48V strip work with smart home systems? Yes. Using a compatible 48V dimming controller, 48V COB strip integrates with Lutron, Loxone, Control4, Casambi, Lightwave, and Crestron systems via DALI, DMX, or 0–10V protocols.
• What is the maximum length I can run from one end? 30 metres from a single power connection. For runs beyond 30 metres, dual-end feeding extends the total — contact our team on 01952 370008 for guidance.
• Can I cut 48V COB strip to a custom length? Yes. Cut points are marked every 50mm along the full 30-metre reel. Cut at any marked point with sharp scissors. We also offer a cut-to-order service — specify your exact length when ordering.
• Will IP67 48V strip survive UK winters outdoors? Yes. IP67 is rated for temporary immersion and withstands sustained rainfall, frost-thaw cycling, and UV exposure. It is the correct minimum IP rating for any permanent outdoor LED strip installation in the United Kingdom.
• Does 48V COB strip produce visible LED dots? No. With 480 LEDs per metre embedded directly into the PCB using COB technology, the light output is completely smooth and dot-free — even without a diffuser cover.
• What is the power consumption for a full 30-metre reel? 300W total (10W per metre multiplied by 30 metres). At average 2026 UK electricity rates of approximately 24.5p per kWh, running a full 30-metre reel for 8 hours per day costs roughly £17–£18 per month.
• Do I need an aluminium profile with 48V COB strip? For runs over 5 metres, an aluminium profile is strongly recommended — it acts as a heat sink that extends LED lifespan, protects the strip from physical damage, and provides a finished appearance. For commercial installations over 10 metres, a profile is considered essential best practice.
• How long does 48V COB strip last? Rated lifespan is 50,000 hours. At 8 hours of daily use, that is approximately 17 years before output drops to 70 percent of the original brightness (L70 standard). Mounting on a heat-sinking aluminium profile and running the driver within its rated wattage both contribute to reaching or exceeding that figure.
• Can 48V COB strip be used in bathrooms? Yes — IP67 rated 48V COB strip is suitable for bathroom zones 1 and 2 under BS7671. Mount the 48V driver outside the bathroom or in zone 3. All permanent bathroom wiring must be completed by a qualified electrician under Part P regulations. 48V DC falls within the SELV voltage threshold (with a suitably isolated driver), providing reduced shock risk in damp environments.
• Does 48V COB strip work with Triac wall dimmers? Yes — pair a Triac-dimmable 48V driver with a trailing-edge wall dimmer for simple brightness control from a standard wall plate. Leading-edge dimmers frequently cause flicker — replacing one with a trailing-edge model costs approximately fifteen pounds and typically resolves the issue. For commercial installations, 0–10V, DALI, and PWM provide more precise control.
• Can I mix 48V COB strip with 24V strip in the same installation? Yes, but each voltage must have its own dedicated driver. A 48V strip section connects to a 48V driver and a 24V strip section connects to a 24V driver — they cannot share the same power source. This is common in 2026 projects where a long corridor uses 48V and shorter branching rooms use 24V.
• What cable gauge is needed for 48V COB strip installations? 48V draws half the current of 24V at the same wattage, so thinner cable is acceptable for equivalent distances. Use 0.75mm cable minimum for driver-to-strip runs under 10 metres. For runs between 10 and 20 metres, step up to 1.0mm. Runs approaching 30 metres benefit from 1.5mm cable to minimise voltage drop in the DC supply line.
• Is 48V COB strip suitable for stairwell lighting in multi-storey buildings? Yes — 48V COB strip is widely specified for continuous stairwell lighting in 2026 commercial buildings. A single 30-metre run from one driver covers multiple floors without mid-point injection. The constant-current IC design maintains consistent brightness from top to bottom.
• Does UK LED Lights offer a cut-to-order service for 48V COB strip? Yes — specify your exact length when ordering and our team cuts at the nearest 50mm interval before dispatch. No waste, no on-site trimming required. Email sales@ukledlights.co.uk with your measurements or call 01952 370008 to arrange bespoke cutting.
• Can 48V COB strip be controlled by a building management system? Yes — using a DALI-compatible 48V driver, the strip integrates directly with building management systems including Lutron, Loxone, Control4, Casambi, and Crestron. DALI provides individual channel addressing, scheduled scenes, and centralised control across multiple zones.
• What warranty covers 48V COB strip from UK LED Lights? UK LED Lights single colour COB strip carries a 5-year warranty — one of the longest in the UK LED strip market in 2026.
