LED Strip Lights for Campervan Conversions: The Complete UK Guide (2026)

You have stripped the van, insulated the walls, and now you are staring at bare metal wondering how to light this space you are about to call home. LED strip lights are the most practical lighting solution for campervan conversions — they are thin enough to fit behind panels, light enough to add zero meaningful weight, and efficient enough to run for hours from a leisure battery. But choose the wrong type, wire it incorrectly, or skip the mounting basics, and you will be ripping it out and starting again within six months. This guide is written for UK van converters building on Ford Transit, Mercedes Sprinter, VW T5/T6, Renault Master, or any panel van. Whether this is your first conversion or you are upgrading from cheap Amazon strip that has already failed, every recommendation here comes from hands-on experience fitting LED lighting in vans — not from copying a product listing. We cover voltage choice, colour temperature for living spaces, zone-by-zone layout planning, wiring to a leisure battery, and the real-world problems nobody else warns you about: condensation, vibration, voltage drop, and adhesive failure. 12V COB LED strip · CRI90+ · FreeCut technology · IP65–IP67 rated · 5-year warranty · Free UK delivery Quick decision summary: For most DIY van builds in 2026, use 12V COB strip at 10W/m in warm white (2700K–3000K) for living areas, natural white (4000K) over the kitchen worktop, and IP67 rated strip near the sink and wet areas. Mount in aluminium profiles with mechanical clips — not adhesive tape alone. Budget 8–12 metres of strip total, one 12V driver, and a simple PWM dimmer. Total cost for a complete van lighting system: approximately £120–£200. Who this guide is for: First-time van converters fitting LED lighting for the first time. Experienced builders upgrading from cheap LED strip that has already failed. Professional converters looking for a reliable UK supplier with technical support. Anyone building on a Transit, Sprinter, T5/T6, Master, or similar panel van. Who this guide is NOT for: If you need lighting for a factory-built motorhome or touring caravan with an existing 12V system, see our motorhome and caravan LED lights page. If you are choosing between COB and SMD strip, read our COB vs SMD comparison guide first. Common buying mistakes to avoid in 2026: Using IP20 strip inside a campervan: Condensation from overnight temperature cycling kills IP20 strip within 3–6 months. Use IP65 minimum for all interior van areas, IP67 for kitchen and wet zones. Relying on adhesive tape alone: Road vibration and heat cycling peel adhesive tape off van panels within weeks. Mount strip inside aluminium or silicone profiles with mechanical clips. Buying 24V strip for a 12V van system: You will need a DC-DC step-up converter, adding cost, a failure point, and 10–15% energy loss. Start with 12V strip and connect directly to your leisure battery circuit. Skipping a fuse on the LED circuit: Every LED circuit must be individually fused from the leisure battery distribution board. An unfused short circuit in the lighting can drain or damage the battery. Choosing CRI70 budget strip for a living space: You are living in this van — food looks grey, skin tones look flat, and wood grain loses warmth under low-CRI light. CRI90+ is the practical minimum for any space you spend time in. Jump to section: Why LED strip lights work for campervans 12V or 24V — which voltage?

LED strip lights suit campervans because they are extremely thin (typically 2–4 mm), draw very little power from a leisure battery, produce minimal heat in a confined space, and can be cut to exact lengths to fit any van layout. No other lighting type offers this combination of flexibility and efficiency for a mobile living space in 2026. Compare strip lights to the alternatives van converters typically consider: Puck lights and spot lights: Require individual cutouts in ceiling panels, add more wiring complexity, create harsh pools of light with dark gaps between fixtures, and each unit draws more current than a metre of LED strip. Rope lights: Thicker, less efficient, lower colour rendering, and the plastic tube yellows within 12–18 months in a van that experiences temperature extremes from -5°C in winter to 50°C+ in a parked summer van. Fluorescent tubes: Fragile, heavy by comparison, contain mercury, and produce a constant buzz that is noticeable in a quiet van at night. Panel lights: Require flat mounting surfaces that are rare in a van — the ceiling ribs, curved walls, and irregular panels make panel lights impractical without significant framework. LED strip sits flat against any surface, follows curves when mounted in a flexible silicone profile, and distributes light evenly across an entire run. In a space measuring roughly 2.4 m wide and 5–7 m long, you need even light distribution more than raw brightness — and strip delivers exactly that. The efficiency numbers matter when you are living off-grid. A typical 5-metre run of 12V COB strip at 10W/m draws just 4.17A from a 12V leisure battery. That is 24 hours of continuous light from a 100Ah lithium battery — far more than any evening requires. A comparable set of four puck lights drawing 5W each would produce less total light while drawing a similar current, with uneven coverage. ATOM LED 12V COB strip range is specifically suited to van builds — CRI90+ colour rendering means colours look accurate inside your living space, and FreeCut technology lets you cut at any point along the strip without voiding the 5-year warranty. Should you use 12V or 24V LED strip in a campervan? For most DIY campervan conversions, 12V LED strip is the practical choice because it runs directly from your 12V leisure battery system without a voltage converter. 24V strip offers lower voltage drop on longer runs but requires a DC-DC step-up converter, adding cost, complexity, and another point of failure to your electrical system. Every leisure battery in a UK campervan — whether lead-acid, AGM, or lithium — operates at a nominal 12V (actual range 11.8V–14.4V depending on charge state and whether shore power or solar is active). Your entire van electrical system — water pump, USB sockets, diesel heater, fridge — runs on 12V. Adding 24V strip means adding a 12V-to-24V step-up converter, which typically costs £20–£45, wastes 5–10% of power as heat during conversion, and introduces a component that can fail. Factor 12V LED strip 24V LED strip (with converter) Leisure battery compatibility Direct connection — native voltage Requires 12V-to-24V DC-DC converter Voltage drop on a 5 m run at 10W/m Approximately 4–6% brightness loss Approximately 2–3% brightness loss Voltage drop on a 7 m run at 14W/m Approximately 7–9% brightness loss Approximately 3.5–4.5% brightness loss Wiring complexity Simple — connects to 12V distribution board Moderate — converter must be fused and mounted Maximum recommended single-feed run 5 metres 10 metres (from converter output) Power efficiency No conversion loss 5–10% loss through converter Component cost Strip + fuse + wire only Strip + converter + extra fuse + wire Failure points Fewer — no converter to fail Converter failure kills all lighting on that circuit Best for Van conversions under 7 m total strip Larger builds, or if you already run a 24V system The practical recommendation for 90% of UK van builds: Use 12V COB LED strip wired in parallel from your leisure battery distribution board. If your longest single run exceeds 5 metres, either feed from both ends or split into two parallel runs. This eliminates the need for a converter entirely and keeps your electrical system simple — which matters when you are troubleshooting at 11pm on a Welsh hillside. When 24V makes sense: If you are building a larger van (LWB Sprinter or Crafter) with over 12 metres of total strip, or if you are already running a 24V system for other reasons (some commercial van conversions use 24V), then 24V strip with a quality DC-DC converter is worth the added complexity. The reduced voltage drop across long runs gives you noticeably more even lighting. For a detailed comparison of how voltage affects installation choices, see our complete LED strip installation guide. What colour temperature works best for van living? Warm white (2700K–3000K) is the best choice for the main living, sleeping, and lounge areas of a campervan. It creates a relaxing atmosphere that makes a small space feel comfortable rather than clinical. Natural white (4000K) works well for the kitchen prep area where you need to see food colours accurately. Avoid cool white (5000K+) as a primary van light — it makes a small metal box feel like a hospital corridor. Colour temperature affects how a space feels, and in a campervan this matters more than in a house. You are spending every evening in a space roughly the size of a large bathroom. The wrong colour temperature creates discomfort that is hard to identify but impossible to ignore. 2700K (extra warm white): Closest to candlelight. Ideal for bed area, overhead ambient lighting above seating, and anywhere you want maximum cosiness. Popular choice for van builds focused on weekend camping and relaxation. 3000K (warm white): The most versatile choice for van conversions in 2026. Warm enough for evening comfort, bright enough for general tasks like reading, cooking, and organising. This is the temperature most professional van conversion companies choose as standard. 4000K (natural white): Crisp without being harsh. Excellent for a dedicated kitchen strip where you need accurate colour rendering for food preparation. Also useful as a secondary task light above a desk or workbench area. 5000K–6500K (cool white): Not recommended as primary lighting in a van. Creates a cold, sterile atmosphere in an already small space. The exception: if you are building a mobile workshop or trade van where task visibility is the only priority. The CRI factor most van builders ignore: CRI (Colour Rendering Index) measures how accurately a light source shows colours. A CRI of 80 — typical of cheap LED strip — makes your van interior look flat and washed out. CRI90+ makes wood panelling look like actual wood, food looks appetising, and skin tones look natural. When you are living in this space, not just passing through it, CRI90+ is not a luxury — it is the difference between a space that feels like home and one that feels temporary. Every ATOM LED COB strip light is rated CRI90+ as standard. Mixing temperatures: Many successful van builds use two circuits — warm white (3000K) as the main ambient light and natural white (4000K) as a secondary task light in the kitchen area only. Wire these on separate switches so you can use each independently. This approach gives you maximum flexibility without the complexity and colour-mixing limitations of RGBW strip. How many lumens per metre do you need in each van zone? A campervan needs approximately 300–500 lumens per square metre in living areas, 500–700 lm/m² in the kitchen zone, and 100–200 lm/m² in the sleeping area. These figures are lower than residential recommendations because the surfaces are closer together — a van ceiling is typically 1.4–1.8 m above the floor, so light does not disperse as far before reaching your eye. The mistake most first-time van builders make is treating a campervan like a house and over-specifying lumens. In a room with a 2.4 m ceiling, you need more lumens because the light travels further and bounces off more surfaces before reaching the task area. In a van with a 1.5 m ceiling height at the centre, a 600 lm/m strip at 1.2 m above the floor puts the light source just 30 cm above your head while seated. That is extremely close, and high-output strip at that distance creates glare rather than comfortable illumination. Van zone Recommended strip type Colour temp Lumens per metre IP rating Mounting method Main ceiling (ambient) 12V COB single colour 3000K 400–600 lm/m IP65 minimum Aluminium profile screwed to ceiling battens Kitchen worktop (task) 12V COB single colour 4000K 600–800 lm/m IP65 minimum Under-cabinet aluminium profile Bed area (accent) 12V COB single colour 2700K 200–400 lm/m IP65 Silicone profile for soft diffused glow Wardrobe/storage 12V COB single colour 4000K 300–500 lm/m IP20 acceptable (sealed area) Self-adhesive inside closed cabinet Bathroom/wet area 12V COB single colour 3000K 400–600 lm/m IP67 required Silicone sealed profile Under-seat/mood 12V COB or neon flex 2700K or RGB 100–300 lm/m IP65 Hidden channel or neon flex rail Exterior awning 12V COB outdoor 3000K 500–700 lm/m IP67 minimum Aluminium profile with end caps sealed The dimming advantage: Rather than trying to specify the exact lumen output for each zone, choose a strip with moderate-to-high output (600–800 lm/m) and wire it through a dimmer. This gives you bright task lighting when cooking and soft ambient lighting when relaxing — from a single strip type. It simplifies your build because you stock one strip type and one driver type. For strip options suitable for each zone, browse the full COB LED strip collection and filter by voltage and output. COB or SMD strip — which is better for a van build? COB (Chip-on-Board) strip is the better choice for campervan conversions in 2026. It produces a continuous, dot-free line of light that eliminates the visible hot spots you see with SMD strip — and in a van where the strip is often visible at close range, that dot-free output makes a significant difference to how professional the build looks and feels. The technical differences that matter in a van environment: Dot-free light output: COB strip places LEDs so close together that the light merges into a smooth, continuous line. SMD strip has visible individual LED dots spaced 5–10 mm apart. In a house with strip hidden behind a coving, this difference is minor. In a van where you are often looking directly at the strip from 50 cm away, the SMD dots create a cheap, unfinished look. Heat distribution: COB strip distributes heat more evenly across its full width because the LED chips are embedded directly in the PCB substrate. SMD strip concentrates heat at each individual chip location. In a van that can reach 50°C+ inside during summer parking, even heat distribution prolongs strip life. Flexibility: COB strip is slightly more flexible than rigid SMD strip, making it easier to follow gentle curves in van ceiling panels and wall cladding. For tighter curves, you still need a flexible silicone profile or LED neon flex. CRI performance: ATOM LED COB strip achieves CRI90+ across all colour temperatures. Budget SMD strip from general retailers typically delivers CRI70–CRI80, which produces noticeably duller colour rendering in a living space. Cut points: ATOM LED COB strip uses FreeCut technology — you can cut at any point along the strip without voiding the warranty. Standard SMD strip can only be cut at fixed intervals (usually every 50 mm or 100 mm), which limits your ability to fit exact van dimensions. When SMD still works: If your budget is tight and the strip will be completely hidden behind a diffuser or inside a sealed profile where dot visibility is not a factor, SMD strip at a lower price point can work. But for any visible installation — ceiling runs, bed surrounds, kitchen accent lighting — COB is worth the modest price difference. For a detailed technical comparison, read our COB vs SMD LED strip buying guide. What IP rating do you need inside a campervan? IP65 is the minimum recommended rating for all campervan LED strip installations, even in areas that appear dry. The reason: temperature cycling creates condensation inside every van, every night. A van parked at 5°C overnight with residual warmth from cooking and body heat produces moisture on metal and cold surfaces — and IP20 strip with exposed PCB components fails within 3–6 months in these conditions. This is the advice that almost every campervan LED guide gets wrong. They recommend IP20 for interior areas as if a van interior is the same as a living room. It is not. A campervan is an insulated metal box that experiences temperature swings of 30–40°C in a single day — from freezing overnight to solar-heated during the day in spring and autumn. This cycling produces condensation on any surface cooler than the dew point, and that includes the back of ceiling panels where LED strip is typically mounted. IP20 (no protection): The exposed copper PCB traces and solder joints corrode in condensation. We see failed IP20 strip from van builds within 3–6 months, typically showing green copper oxide on the solder points and intermittent sections that flicker or go dark. Not recommended for any campervan area. IP65 (silicone coating or nano-coating): The minimum acceptable rating for campervan use. The silicone layer protects solder joints and PCB traces from condensation and light moisture. Suitable for ceiling, wall, and storage areas that are not directly exposed to water. This is the recommended standard for all general van areas in 2026. IP67 (silicone tube or full encapsulation): Required for kitchen zones (near sink), bathroom/wet areas, any strip near the sliding door or rear doors that may be exposed to rain during open-door cooking, and exterior-mounted strip. Browse outdoor-rated COB strip for IP67 options. IP68 (continuous submersion rated): Only necessary if you are mounting strip on the exterior of the van in a fully exposed location, or inside a shower cubicle with direct water spray. Overkill for most interior van applications. The cost of getting this wrong: Replacing failed LED strip in a completed van build is not a quick job. The strip is behind panels, above cladding, inside profiles that are screwed to the ceiling structure. Ripping out and replacing a 4-metre ceiling run after the build is finished takes 3–4 hours and involves removing trim, unscrewing profiles, desoldering connections, and refitting everything. Spending the extra £5–£10 per 5 m reel for IP65 over IP20 avoids this entirely. How do you wire LED strip lights to a leisure battery? Wire LED strip lights from the leisure battery via a fused distribution board, using an appropriate inline fuse for each LED circuit. The positive feed runs from the battery through a fuse to a switch (and optionally a dimmer), then to the LED strip. The negative return runs back to the common negative bus bar. Always use parallel wiring for multiple strip runs — never daisy-chain in series. The wiring path for a typical campervan LED circuit: Leisure battery positive terminal connects to your main fuse box or battery management system (BMS on lithium) via appropriately rated cable. Distribution board: The fused distribution board splits the battery supply into individual circuits. Each LED circuit gets its own fuse — typically 3A–5A for a single strip run of 5–8 metres at 10W/m. Fuse sizing: Calculate the maximum current draw: total watts divided by 12V. For example, 5 m × 10W/m = 50W ÷ 12V = 4.17A. Use a 5A blade fuse. Always round up to the next standard fuse size, but never more than double the calculated draw. Switch: A simple on/off switch between the fuse and the strip. If using a dimmer, the dimmer replaces the switch in this position. Use a switch rated for at least twice the circuit current. Wire to strip: Run the positive and negative wires to the LED strip location. Use appropriate gauge cable — see the table below. Strip connection: Connect to the strip using solder joints (most reliable in a vibrating van) or quality solderless connectors. Solder all joints and apply heat-shrink tubing for a permanent, vibration-resistant connection. Negative return: The negative wire from the strip returns to the common negative bus bar, which connects back to the leisure battery negative terminal. Wire gauge guide for 12V LED circuits in vans: Total wattage Current draw (at 12V) Run length up to 3 m Run length 3–5 m Run length 5–8 m Up to 30W 2.5A 0.75 mm² minimum 1.0 mm² 1.5 mm² 30–60W 2.5–5A 1.0 mm² 1.5 mm² 2.5 mm² 60–100W 5–8.3A 1.5 mm² 2.5 mm² 4.0 mm² 100–150W 8.3–12.5A 2.5 mm² 4.0 mm² 6.0 mm² Parallel wiring — non-negotiable: If you have multiple strip runs (ceiling, kitchen, bed area), each one should have its own positive and negative wires running back to the distribution board. Never wire strip runs in series (daisy-chaining the output of one into the input of the next). Series wiring multiplies voltage drop — by the third strip in a series chain, you will have visible dimming and colour shift. Sargent and Schaudt systems: Many UK-built campervans and van conversions use Sargent (common in Bailey, Swift, and similar) or Schaudt (common in European conversions) electrical management systems. Both have spare fused outputs on the distribution board specifically for additional 12V circuits. Check your system manual for available spare circuits before running new cable — you may already have a fused output waiting. For LED drivers and power supplies suited to 12V van systems, see the LED power supply range. How far can you run 12V LED strip in a campervan before voltage drop becomes visible? On 12V LED strip at 10W/m, visible voltage drop typically starts around 4–5 metres from a single feed point — the far end dims by approximately 5–8% compared to the feed end. At 7 metres (a common rear-to-front ceiling run in an LWB van), you can lose 8–12% brightness at the far end, which is noticeable when the strip is on a flat white ceiling. Parallel wiring or dual-end feeding eliminates this. Voltage drop is the most under-discussed problem in campervan LED installations. At 12V, the current flowing through the strip's narrow copper PCB traces creates resistance that increases with distance. The voltage available to each LED decreases progressively from the feed point to the far end. This shows up as visible dimming — the strip is noticeably brighter near the wire connection and dimmer at the opposite end. The calculation for a typical LWB van ceiling run: Strip specification: 12V COB, 10W/m, 5 m long Total power: 50W Current at feed point: 50W ÷ 12V = 4.17A Voltage at feed end: 12.0V (assuming regulated supply) Voltage at far end (typical): approximately 11.3–11.5V Brightness loss at far end: approximately 4–6% At 7 metres with 14W/m strip (common for a brighter build): Total power: 98W Current: 8.17A Voltage at far end: approximately 10.8–11.1V Brightness loss: approximately 8–12% — clearly visible to the eye How to fix voltage drop in a van: Dual-end feed: Run power wires to both ends of the strip. This halves the effective distance and cuts voltage drop by approximately 75%. The most effective single fix. Parallel runs: Instead of one 7 m run, use two 3.5 m runs each with their own feed wires meeting in the middle. Each run has minimal drop. Heavier feed wire: Use 2.5 mm² or 4 mm² cable from the distribution board to the strip. This reduces resistive loss in the feed cable (though it does not fix drop within the strip itself). Consider 24V strip with a converter: If your total strip exceeds 10 m and you want single-feed simplicity, 24V strip experiences voltage drop at half the rate of 12V at the same wattage. This may justify the added cost and complexity of a converter. Real-world test: Before permanently mounting your strip, connect it temporarily at full length with the feed wires you plan to use. Turn it on in the dark and look along the length. If you can see the far end dimming, either shorten the run, add a second feed, or switch to parallel wiring. Five minutes of testing saves hours of rework. Why does LED strip fall off van walls — and how do you fix it? LED strip falls off van walls because standard 3M adhesive tape — even VHB (Very High Bond) — fails under the combination of vibration, temperature cycling, and surface curvature that every van experiences. A van on UK roads vibrates constantly, interior temperatures swing 30–40°C daily, and most van surfaces are slightly curved rather than perfectly flat. These three factors combined defeat adhesive-only mounting within weeks to months. This is the single most common complaint we hear from van builders who fitted LED strip themselves. The strip looked perfect on day one, started peeling at the corners within a fortnight, and was hanging loose within two months. The problem is not the adhesive quality — it is the application environment. Vibration: A van on a British B-road transmits constant micro-vibrations through every panel. These vibrations fatigue the adhesive bond at the edges of the strip, where stress concentrates. Over hundreds of miles, the bond weakens progressively until the strip peels. Temperature cycling: The adhesive bond strength varies with temperature. At 50°C (a parked van in summer sun), adhesive softens significantly. At -5°C (a winter night), it becomes brittle. This daily cycle of soft-hard-soft works like repeated bending — it fatigues the bond. Surface curvature: Van ceiling panels and wall cladding are rarely flat. Even slight curvature creates peel stress at the edges of the strip, where the strip wants to spring back to its natural flat shape. The adhesive fights this constantly. Surface contamination: Plywood, MDF, and timber cladding contain oils and resins that migrate to the surface over time, undermining the adhesive bond even after cleaning with IPA. The solutions — in order of reliability: Aluminium profile with mechanical fixings (most reliable): Screw an aluminium profile to the ceiling battens or wall structure, then press the strip into the profile channel. The profile holds the strip mechanically — the adhesive becomes a secondary bond rather than the primary mounting. This is the professional method and the one we recommend for every van build. Silicone profile (excellent for curves): Flexible silicone profiles bend to follow curved surfaces and hold the strip inside a flexible sleeve. Secure the silicone profile to the surface with clips or adhesive at 200 mm intervals, and the strip stays put regardless of vibration. Mechanical clips at 150–200 mm intervals: If using strip without a profile, add small mounting clips (available from accessories) every 150–200 mm along the run. These provide mechanical retention even if the adhesive fails. Clean and prime the surface properly: If relying on adhesive, clean the surface with IPA, then apply a 3M adhesion promoter (Primer 94 or equivalent) before pressing the strip on. Apply firm pressure for 10–15 seconds per 100 mm section and allow 24 hours for the adhesive to cure before driving. For aluminium mounting profiles suitable for van builds, including low-profile recessed options that sit flush with ceiling cladding, browse the ATOM LED profile range. Which aluminium profiles work on curved van surfaces? Standard rigid aluminium profiles work for flat ceiling panels and wall sections, but for curved van surfaces — particularly the roof arch and wheel arch areas — you need either a flexible silicone profile or a bendable aluminium profile designed for curves with a radius down to approximately 500 mm. For tighter curves (under 500 mm radius), silicone profiles or LED neon flex are the only practical options. Van roofs and walls are not flat. The Transit roof panel has a gentle crown with an effective radius of approximately 1,500–2,000 mm across the width. The Sprinter has a higher crown with a tighter radius. VW T5/T6 roof panels, particularly after pop-top conversions, have compound curves that vary across the surface. Standard rigid extrusion profiles designed for flat residential ceilings will not follow these curves — they either sit proud of the surface with visible gaps, or crack if you try to force-bend them. Rigid aluminium profiles (flat surfaces only): Use for any section of ceiling or wall where the surface is flat over the profile length. This includes purpose-built flat ceiling panels in fully-clad interiors, overhead locker fascias, and flat wall sections. Mount with screws directly into the batten structure behind the cladding. Flexible silicone profiles: The best solution for curves in van builds. They bend freely to follow any surface contour, protect the strip from physical damage, and produce a soft, diffused light output. Secure them with clips or adhesive at regular intervals. Available from the silicone profile range. LED neon flex: For very tight curves (under 300 mm radius), such as around wheel arch trim, window surrounds, or decorative ceiling arches, LED neon flex bends cleanly without kinking and produces a smooth, diffused glow that looks integrated rather than retrofitted. It also adds a modern aesthetic that works particularly well in contemporary van interiors. Recessed profile in flat panel sections: If you are building custom ceiling panels (common in full van conversions), route a channel into the panel material and recess a slim aluminium profile flush with the surface. This creates a clean, integrated look with the profile edges invisible after painting or covering. Mounting profiles in a van — key differences from residential installation: Screws, not adhesive: Always screw profiles to structural battens or the van body (through insulation). Adhesive-only mounting fails in a vibrating van for the same reasons described in the strip adhesive section above. Allow for thermal expansion: Aluminium expands and contracts with temperature. In a van that experiences 40°C+ temperature swings, a 2-metre profile can expand approximately 1 mm. Leave a 1–2 mm gap at each end, particularly if the profile is recessed into a tight channel. End caps and sealing: Fit end caps to every profile run. In a van environment, dust, condensation, and insects find their way into open profile channels. Sealed end caps keep the strip and diffuser clean long-term. How do you dim LED strip lights on a 12V van system? The simplest and most reliable way to dim 12V LED strip in a campervan is a 12V PWM (Pulse Width Modulation) dimmer installed between the power supply and the strip. PWM dimmers are specifically designed for 12V DC circuits, cost £8–£25 depending on features, and produce smooth flicker-free dimming from 0–100% brightness. Do not use mains AC dimmers — they are incompatible with 12V DC systems. Dimming is one of the most important features in a van lighting system. You need full brightness when cooking, medium brightness when socialising, and very low brightness for winding down at night without disturbing a partner. A single LED circuit with a good dimmer replaces the need for multiple light sources at different brightness levels. 12V PWM inline dimmer (recommended): Wires between the power feed and the strip. A rotary knob, touch panel, or wireless remote controls brightness. Simple, reliable, no compatibility issues with single-colour LED strip. Cost: £8–£20 for basic rotary, £15–£25 for wireless remote versions. 12V smart dimmer with Bluetooth: Allows dimming control from a phone app. Useful if the dimmer is mounted in an inaccessible location. Some models include timer and scheduling functions. Cost: £15–£30. Multi-zone controller: If you have multiple LED circuits (ceiling, kitchen, bed), a multi-zone LED controller lets you dim each zone independently from a single remote or panel. This is the tidiest solution for builds with 3+ lighting zones. What not to use: Mains AC dimmers (Varilight, trailing-edge, leading-edge types): These are designed for 230V AC mains circuits and are incompatible with 12V DC. They will not work and may damage the strip or dimmer. Resistive dimmers: These waste power as heat by inserting resistance into the circuit. Inefficient, generate heat in a confined van space, and produce uneven dimming. PWM dimmers are superior in every way. Dimmable drivers with mains dimmers: This combination is designed for household installations where mains AC feeds a dimmable LED driver. In a van with a 12V DC leisure battery system, there is no mains supply to dim (unless you are running an inverter, which adds needless complexity and power loss). RGB and RGBW dimming: If you install RGB or RGBW strip for mood lighting (under seating, behind headboard, etc.), you need a dedicated RGB/RGBW controller instead of a standard dimmer. These controllers handle both colour selection and brightness. Important: use a non-dimmable constant voltage driver feeding the controller — dimmable drivers combined with RGB controllers cause flicker, colour shift, and premature component failure. How do you plan a zone-by-zone lighting layout for a van conversion? Plan your van lighting in five zones: main ceiling ambient, kitchen task, bed area accent, storage/utility, and optional exterior. Each zone needs its own switched circuit from the distribution board, its own fuse, and strip specified for that zone's brightness, colour temperature, and moisture exposure. Map these zones onto your van floor plan before buying a single component. The planning phase is where most van builds either succeed or fail on lighting. Builders who plan zone by zone end up with flexible, comfortable lighting that works for every situation — cooking, reading, relaxing, sleeping. Builders who buy a single 10 m reel of one strip type and run it everywhere end up with light that is too bright in the bedroom, too dim in the kitchen, and the wrong colour temperature for everything. Zone 1 — Main ceiling ambient: Purpose: General illumination for the entire van interior Strip: 12V COB, 3000K warm white, 500–600 lm/m, IP65 Typical length: 3–6 metres depending on van length and layout Mounting: Aluminium profile screwed to ceiling battens, centred or split into two parallel runs either side of the ceiling centre line Control: PWM dimmer on a rocker switch — this is the most-used light in the van and needs easy access Zone 2 — Kitchen task: Purpose: Bright, accurate light for food preparation Strip: 12V COB, 4000K natural white, 600–800 lm/m, IP65 or IP67 (near sink) Typical length: 0.6–1.2 metres under overhead cabinet Mounting: Slim aluminium profile under cabinet, angled towards the worktop Control: Separate switch, dimmer optional (most builders leave this at full brightness) Zone 3 — Bed area accent: Purpose: Low, warm reading light and ambient glow for winding down Strip: 12V COB, 2700K extra warm white, 200–400 lm/m, IP65 Typical length: 1–3 metres along headboard, above or behind bed panels Mounting: Silicone profile recessed into headboard panel, or hidden behind a trim strip for indirect uplight/downlight Control: PWM dimmer accessible from bed — ideally a remote or bedside rotary Zone 4 — Storage and utility: Purpose: Light inside wardrobes, overhead lockers, garage area (under bed storage) Strip: 12V COB, 4000K natural white, 300–500 lm/m, IP20 acceptable inside sealed cabinets Typical length: Short sections 300–600 mm each, triggered by door/lid switches Mounting: Self-adhesive (acceptable in sealed dry cabinets), or clips Control: Magnetic reed switch on the door/lid — light activates when opened Zone 5 — Exterior (optional): Purpose: Lighting under awning, at rear doors for cooking/socialising outside Strip: 12V COB, 3000K warm white, 500–700 lm/m, IP67 minimum Typical length: 1–3 metres under awning rail or above rear doors Mounting: Aluminium profile with sealed end caps, mechanically fixed to van body Control: Separate switch inside the van — never leave exterior lights on unattended For connectors, clips, and mounting accessories needed for a multi-zone van build, check the accessories range. What mistakes do first-time van builders make with LED lighting? The most common mistakes are: using IP20 strip that fails from condensation, running a single long strip in series instead of parallel, relying solely on adhesive without mechanical fixing, choosing cool white colour temperature for a living space, skipping fuses on LED circuits, and powering strip while it is still on the reel during testing. Every one of these is avoidable with basic planning. Using IP20 strip and wondering why it fails: As covered in the IP rating section, a campervan is not a dry indoor environment. Condensation forms overnight even in summer. IP20 strip with exposed copper traces and solder joints corrodes. Minimum IP65 for all van areas — this one decision prevents the most common LED failure in van builds. Running one long strip in series from end to end: A 7 m continuous run of 12V strip fed from one end loses 8–12% brightness at the far end. The fix: either dual-end feed (power wires to both ends) or split into two parallel runs meeting in the middle. Each run gets its own feed wires back to the distribution board. Adhesive-only mounting on plywood cladding: Plywood and timber cladding contain natural oils and resins that migrate to the surface and undermine adhesive bonds. Combined with van vibration, adhesive alone fails within weeks to months. Use aluminium profiles with screws, silicone profiles with clips, or at minimum add mechanical clips every 150–200 mm. Choosing cool white (5000K+) for the entire van: Cool white makes a small metal box feel sterile and uncomfortable. Warm white (3000K) for living areas and natural white (4000K) for the kitchen only. You can always add brightness with a higher-output strip — you cannot fix the wrong colour temperature without replacing the strip. No fuses on LED circuits: Every LED circuit must be individually fused from the distribution board. Without a fuse, a short circuit in the strip (from a damaged section, moisture ingress, or pinched wire) draws uncontrolled current from the leisure battery. This is a fire risk. Blade fuses are cheap, easy to install, and non-negotiable for safety. Powering strip while coiled on the reel: LED strip generates heat when powered. When coiled, the heat cannot dissipate and builds up in the centre of the reel. This damages the adhesive, can degrade the LEDs, and in extreme cases presents a fire risk. Always uncoil strip fully before testing. Never power it while rolled up. Mounting strip on bare metal without insulation: The exposed solder points on the strip PCB can short-circuit against bare metal van bodywork. Always insulate the mounting surface — use an aluminium profile (the anodised coating provides insulation), apply Kapton tape between strip and metal, or mount on timber/plastic cladding. Buying cheap RGB strip as the main light source: RGB strip cannot produce clean white light. It produces a cold, violet-tinged approximation that is adequate for accent mood lighting but unusable as a primary light source for living, cooking, or reading. If you want colour-changing mood lighting plus functional white light, use RGBW strip with a dedicated white channel — or, more practically, install separate single-colour white strip for functional lighting and a short RGB run for accent only. Forgetting about battery draw: LED strip draws continuously while it is on. In an off-grid van without solar, leaving 50W of lighting on all evening for 5 hours draws approximately 21Ah from a 12V battery. On a 100Ah lead-acid battery (usable capacity ~50Ah), that is 42% of your available power. Plan your strip wattage and dimming strategy with battery capacity in mind. How much power do LED strip lights draw from a leisure battery? Power draw depends on the strip wattage and total length installed. A typical van build with 8 metres of 12V COB strip at 10W/m draws 80W total, which is 6.67A from a 12V battery. On a 100Ah lithium battery, that provides approximately 15 hours of continuous full-brightness lighting — far more than most evenings require, and dimming to 50% doubles that figure. Strip type (12V) Watts per metre Total for 5 m Total for 8 m Amps from 12V Hours on 100Ah lithium (full brightness) Hours at 50% dim COB economy (5W/m) 5W 25W 40W 3.33A (8 m) 30 hrs 60 hrs COB standard (10W/m) 10W 50W 80W 6.67A (8 m) 15 hrs 30 hrs COB high output (14W/m) 14W 70W 112W 9.33A (8 m) 10.7 hrs 21.4 hrs COB premium (20W/m) 20W 100W 160W 13.33A (8 m) 7.5 hrs 15 hrs SMD 5050 (14.4W/m) 14.4W 72W 115.2W 9.6A (8 m) 10.4 hrs 20.8 hrs Important notes on these figures: Lithium vs lead-acid: A 100Ah lithium battery delivers approximately 95Ah of usable capacity (95% depth of discharge). A 100Ah lead-acid or AGM battery delivers approximately 50Ah of usable capacity (50% recommended DoD). The hours shown above are for lithium — halve them for lead-acid/AGM. Dimming halves the draw: A PWM dimmer at 50% reduces current draw to approximately 50%. This is one of the strongest arguments for installing a dimmer — you rarely need full brightness for an entire evening, and dimming extends your battery life proportionally. Solar recovery: A 200W solar panel on the roof generates approximately 40–60Ah per day in UK summer conditions. That is enough to fully recover an evening of moderate lighting use (30–40Ah draw at 50% brightness for 5 hours) with energy to spare for other loads. Multiple circuits at different levels: In practice, you rarely have all zones at full brightness simultaneously. The kitchen task light runs during cooking (30 minutes), the main ceiling runs at 40–60% during the evening (3–4 hours), and the bed light runs at 20% for reading (1 hour). Actual total draw across a typical evening is roughly 15–25Ah — well within the capacity of a properly sized leisure battery setup. Step-by-step: how do you install COB LED strip in a campervan? Installing COB LED strip in a campervan follows the same core principles as any strip installation, with added attention to vibration-resistant mounting, moisture protection, and 12V leisure battery integration. A complete van lighting installation — ceiling ambient, kitchen task, and bed accent — typically takes 4–6 hours for a first-time builder with all components and tools ready. Tools required: Wire strippers (for cable preparation) Multimeter (for confirming polarity and testing voltage) Soldering iron and solder (for permanent strip connections — recommended over solderless connectors in a vibrating van) Heat-shrink tubing and heat gun (for insulating solder joints) Drill and screws (for mounting profiles to battens) Sharp scissors or craft knife (for cutting strip to length) Isopropyl alcohol and clean cloth (for surface cleaning) Cable ties and clips (for cable management along the van structure) Components required: 12V COB LED strip — CRI90+, IP65 minimum, chosen wattage and colour temperature per zone Aluminium or silicone profiles — one per strip run, with end caps and diffuser covers 12V PWM dimmer — one per zone you want dimmable Blade fuses — one per LED circuit, sized to circuit current (see wiring section above) Fuse holders or fused distribution board Appropriately rated cable — see wire gauge table in the wiring section Switches — rocker switches rated for 12V DC at twice the circuit current Connectors — 2-pin for single colour, from the strip accessories range Installation steps: Plan and mark all strip positions on the van ceiling and walls: Use masking tape to mark exactly where each profile will run. Check that mounting screws will not penetrate the outer van skin or any plumbing/electrical routes behind the cladding. Measure each run length precisely — add 50 mm to each measurement for connection tails. Mount the aluminium or silicone profiles: Pre-drill and screw profiles to ceiling battens or structural supports. For silicone profiles, fix clips at 200 mm intervals. Ensure profiles are level and straight — a crooked profile with a lit strip is extremely visible and impossible to ignore. Run cable from the distribution board to each strip location: Use appropriate gauge cable per the wire gauge table. Route cables along the van structure using cable ties. Keep LED circuit cables separate from 230V mains wiring (if your van has a mains hookup). Labelling each cable at both ends saves hours during connection and future troubleshooting. Install fuses and switches: Fit a blade fuse for each LED circuit at the distribution board end. Mount switches in an accessible panel location — consider grouping all lighting switches together for easy access. Cut strip to length: Measure the profile channel internal length and cut the strip to fit. ATOM LED COB strip with FreeCut technology can be cut at any point — no need to find specific cut marks. Use sharp scissors for a clean cut. Solder connection wires to the strip: Tin the strip pads and the wire ends. Solder positive (red or marked) wire to the positive pad and negative (black) wire to the negative pad. Apply heat-shrink tubing over each joint for insulation and vibration resistance. In a van, soldered connections are significantly more reliable than solderless clip connectors, which can work loose from vibration. Press strip into the profile channel: Peel the adhesive backing and press the strip firmly into the profile. Start from one end and work progressively to avoid air bubbles. The adhesive is a secondary bond — the profile channel walls hold the strip mechanically. Fit the diffuser cover and end caps: Snap the diffuser into the profile channel. Fit end caps to both ends. For IP65+ protection in damp areas, apply a thin line of clear silicone sealant around each end cap. Connect cables and test each circuit individually: With the fuse removed, connect the strip wires to the cable at the profile location. Reinstall the fuse and test. Check for even brightness along the full length, correct colour temperature, and smooth dimmer operation. Use a multimeter to confirm voltage at the far end of each strip — if it reads below 11.5V, consider dual-end feeding. Secure all cables and tidy the installation: Cable-tie all loose wiring to the van structure. Ensure no cables are pinched between panels, near heat sources, or resting against sharp metal edges. Label each fuse on the distribution board. Take photographs of the wiring layout before fitting final trim panels — you will thank yourself when troubleshooting in two years' time.

FAQs — LED strip lights for campervan conversions Can I run LED strip from the van starter battery while driving? Technically yes, but it is not recommended. The starter battery voltage fluctuates between 12.0V (engine off) and 14.4V+ (engine running with alternator charging). This overvoltage can shorten LED strip lifespan. Better approach: Run lighting from the leisure battery and use a split-charge relay or B2B charger to keep the leisure battery topped up from the alternator while driving. Key point: Keeping lighting circuits on the leisure battery also means the starter battery is protected — you cannot accidentally flatten it by leaving van lights on. Do I need a fuse for LED strip lights in a campervan? Yes — every LED circuit must have its own fuse. A short circuit in an unfused LED circuit draws uncontrolled current from the leisure battery, which generates heat in the wiring and presents a fire risk. Fuse sizing: Calculate total current (watts ÷ 12V) and use the next standard blade fuse size up. For example, a 50W circuit draws 4.17A — use a 5A fuse. Location: The fuse should be within 300 mm of the positive battery connection or at the fused distribution board. What size wire do I need for campervan LED lights? Minimum 1.0 mm² for runs under 3 metres at up to 5A. For longer runs or higher current, increase to 1.5 mm² or 2.5 mm². Refer to the wire gauge table in the wiring section above for specific recommendations based on wattage, current, and run length. Always use automotive-grade cable rated for vibration and temperature cycling — standard household cable is not suitable for a vehicle environment. Can I use RGB strip as the main light in a campervan? No — RGB strip cannot produce clean white light. When all three channels (red, green, blue) are at maximum, the result is a cold, violet-tinged approximation of white that is unpleasant for daily living. For colour-changing mood lighting: Install a short run of RGB or RGBW strip as a secondary accent (under seating, behind headboard), with separate single-colour white COB strip as your primary lighting. RGBW is better: If you want both colours and white, RGBW strip includes a dedicated white LED channel that produces genuine warm or natural white alongside the RGB colours. How do I stop LED strip falling off in a van? Use aluminium or silicone profiles with mechanical fixings — not adhesive alone. Van vibration and temperature cycling defeat adhesive-only mounting within weeks to months. If you must rely on adhesive: Clean with IPA, apply 3M Primer 94, press firmly for 10–15 seconds per section, and add mechanical clips every 150–200 mm as backup. See section 9 above for the full breakdown of why adhesive fails and the best alternatives. What is the cheapest way to light a campervan? Budget option: A 5 m reel of 12V SMD strip (IP65), a 5A inline fuse, cable, and a basic switch. Total cost: approximately £25–£40. Better value: 5 m of 12V COB strip (IP65, CRI90+) with a slim aluminium profile, PWM dimmer, and fused connection. Total cost: approximately £60–£90. Lasts 5–10 years instead of 1–2 years, looks significantly better, and produces more comfortable light. The cheapest option is often the most expensive long-term — replacing failed budget strip in a completed van build costs more in time and materials than fitting quality strip the first time. Is 12V LED strip safe in a campervan? 12V falls within the SELV (Separated Extra-Low Voltage) threshold under BS7671 when supplied from a suitably isolated source such as a leisure battery. This significantly reduces shock risk under dry conditions. SELV does not mean zero risk. Wet hands, damaged insulation, or standing in water change the risk profile. Always fuse circuits, insulate connections, and avoid running strip through areas where water can pool. For commercial conversions sold to the public: Electrical installations in vehicles used as living accommodation may be subject to BS7671 requirements and should be inspected by a qualified electrician before sale. How long does LED strip last in a campervan? Quality LED strip (CRI90+, proper thermal management) typically lasts 30,000–50,000 hours. At 5 hours per evening, that is 16–27 years of use — the strip will outlast the van. The limiting factor is usually the installation, not the strip. Adhesive failure, moisture ingress (from using IP20), and overheating (from mounting without a profile on poorly ventilated surfaces) cause premature failure long before the LEDs themselves degrade. ATOM LED COB strip carries a 5-year warranty, giving you confidence that the product is backed even in demanding environments. Can I use LED strip lights in a van without a leisure battery? Yes, but only for temporary use. You can connect 12V strip directly to the starter battery for short-term lighting during a build or weekend camping. Use a battery isolator switch so you can disconnect when not in use. Risk: Without a leisure battery and split-charge system, you risk draining the starter battery and being unable to start the engine. For any build intended for regular use, install a dedicated leisure battery system. Portable battery packs (12V lithium power stations): A viable alternative for minimal builds — a 50Ah portable lithium pack can power 5 m of 10W/m strip for approximately 7–8 hours. Do LED strip lights work in freezing temperatures? Yes — LED strip operates efficiently from -20°C to +50°C. Cold temperatures actually improve LED efficiency slightly, so winter camping does not affect light output. The concern is condensation, not cold. When a freezing-cold van warms up from body heat and cooking, moisture condenses on cold surfaces including strip and profiles. This is why IP65 minimum is essential for all van-mounted LED strip. Adhesive is affected: Below 5°C, adhesive becomes brittle and bond strength drops. This reinforces the recommendation to use mechanical mounting methods in any van environment. Should I install LED strip before or after van cladding? Install cable runs and profile mounting points before cladding; fit the strip and diffusers after cladding. This sequence lets you route cables behind panels and screw profile brackets to structural battens, then fit the visible components once the interior finish is complete. Pre-wire everything: Run all cable from the distribution board to each strip location before fitting wall and ceiling panels. Terminate cables with 50 mm service loops at each strip position so you have slack for final connections. Photograph all cable routes before closing up panels — this is critical for future troubleshooting. Can I connect LED strip to a solar charge controller directly? No — never connect LED strip directly to a solar charge controller output. The voltage output from a charge controller fluctuates with solar input and battery state, and can exceed 14.4V during bulk charging. This overvoltage shortens LED lifespan and may void the warranty. Correct approach: Solar panel feeds the charge controller, which charges the leisure battery. LED strip draws from the leisure battery via the fused distribution board. The battery acts as a voltage buffer, smoothing the output to a stable 12.0–13.2V. What is the difference between 12V and 5V LED strip for campervans? 12V LED strip runs from a standard leisure battery system — this is the correct choice for campervan use. 5V strip is designed for USB power banks and computer peripherals, draws high current for modest output, and is not designed for permanent installation. 5V strip limitations: Maximum practical run length of 1–2 metres before significant voltage drop, typically lower CRI, and requires a USB power source rather than integrating with the van electrical system. Exception: 5V addressable LED strip (WS2812B style) is popular for custom lighting effects but requires a dedicated controller and is not recommended for primary van lighting. How do I choose between LED strip and LED neon flex for a van? LED strip (in a profile) is better for primary functional lighting — ceiling, kitchen, bed area — where you need adjustable brightness and efficient light distribution. LED neon flex is better for decorative and accent applications — under seating, around window surrounds, along ceiling arches — where you want a smooth, continuous glow with no visible LED dots and the flexibility to follow tight curves. Many successful van builds use both: COB strip in profiles for functional zones and neon flex for accent details. What do you need for a typical campervan LED strip installation? A standard campervan conversion with ceiling ambient, kitchen task, and bed accent lighting typically requires 8–12 metres of LED strip, three aluminium or silicone profiles, a PWM dimmer, a multi-way fused distribution board, switches, cable, connectors, and basic tools. Budget approximately £120–£200 for a quality installation using CRI90+ COB strip, or £50–£80 for a basic build with SMD strip.
