Quick decision summary: For most motorhome and campervan conversions in 2026, a 12V single-colour COB strip at 10W/m in warm white (2700K-3000K) covers 80% of interior lighting needs. Add a separate run of 4000K natural white over the kitchen worktop, and IP67 strip for the shower area. Budget approximately 5-8 metres of strip for a typical panel van conversion, or 10-15 metres for a coachbuilt motorhome.

Who this page is for: Motorhome owners upgrading factory-fitted halogen or fluorescent lighting, campervan self-builders fitting out a new conversion, caravan owners replacing failing LED modules, and professional converters looking for a reliable UK supplier with technical backup.

Who this page is NOT for: If you need 24V or 48V strip for a mains-powered home installation, see our 24V COB strip range or 48V COB strip range instead. If you need outdoor-rated neon flex for a garden project, visit our LED neon flex collection.

Common buying mistakes to avoid in 2026:

• Buying 24V strip for a 12V leisure battery system: You will need a DC-DC converter, adding cost, wiring complexity, and another potential failure point. Start with 12V strip and eliminate the problem entirely.
• Using IP65 strip in a motorhome shower: IP65 is rated for surface splash only — it will not survive direct water contact in a shower cubicle. You need IP67 minimum for any wet zone.
• Relying on adhesive tape alone: Road vibration, heat cycling from engine bays, and condensation all destroy adhesive bonds within weeks. Use aluminium profiles with mechanical clips for any permanent installation.
• Choosing cheap low-CRI strip: Anything below CRI80 makes food look grey, skin look sallow, and your motorhome interior feel clinical. ATOM LED supplies CRI90+ across every COB strip — the difference is visible immediately.
• Ignoring voltage drop on longer runs: A 6-metre run of 12V strip at 14W/m loses approximately 8-12% brightness at the far end. Parallel wiring or mid-point feed solves this without adding components.

Why choose 12V LED strip lights for a motorhome?

Motorhomes, campervans, and most touring caravans run on 12V DC leisure battery systems. A 12V LED strip connects directly to this supply through the existing fuse board — no voltage converter, no mains inverter, and no unnecessary wiring. This makes 12V strip the simplest, safest, and most efficient lighting choice for any leisure vehicle in 2026.

The majority of UK motorhomes built since the early 2000s use either a Sargent power management unit or a Schaudt EBL distribution board. Both provide fused 12V DC outputs specifically designed for lighting circuits. A 12V COB strip from ATOM LED connects to these outputs with standard automotive-grade wiring — typically 1.0mm or 1.5mm twin-core cable, depending on the total load.

There are practical reasons beyond simplicity. Running 12V natively from a leisure battery avoids the 10-15% energy loss you get from a DC-DC converter (12V to 24V) or the 15-25% loss from an inverter (12V DC to 240V AC). When you are running off-grid on a finite battery, every watt matters.

Feature	12V LED strip (direct connect)	24V LED strip (with converter)	240V LED strip (with inverter)
Connects to leisure battery	Direct — no conversion needed	Requires DC-DC step-up converter	Requires inverter (12V DC to 240V AC)
Energy loss in conversion	0%	10-15%	15-25%
Wiring complexity	Low — standard automotive cable	Medium — converter adds junction	High — requires RCD, mains-rated cable
Maximum single-feed run	Approximately 5m at 10W/m	Up to 20m at equivalent wattage	Varies by driver specification
Safety certification needed	Standard 12V automotive	Standard 12V automotive + converter CE	BS7671 Part P (mains voltage)
Suitable for off-grid use	Yes — maximum battery efficiency	Yes — with reduced efficiency	Drains battery rapidly

If your motorhome or caravan uses a 24V battery bank (common in larger commercial conversions and some expedition vehicles), then 24V strip is the better match. Browse our full voltage range of COB strip lights to find the correct option for your system. For the vast majority of UK leisure vehicles, 12V is the correct choice.

Which colour temperature works best in each motorhome zone?

Different areas of a motorhome need different colour temperatures. Sleeping and lounge areas work best at 2700K warm white for a relaxed atmosphere. Kitchen worktops need 4000K natural white for accurate food preparation. Bathroom areas suit 3000K-3500K — warm enough to feel comfortable, clear enough for grooming tasks.

Colour temperature is measured in Kelvin (K). Lower numbers produce warmer, amber-toned light. Higher numbers produce cooler, bluer-toned light. In a motorhome, getting this right matters more than in a house — because the space is compact, the wrong colour temperature is immediately noticeable and difficult to live with on a two-week trip.

Here is a zone-by-zone breakdown based on real motorhome installations we have supported through our technical team at ATOM LED in Telford:

Motorhome zone	Recommended colour temperature	Recommended brightness (lm/m)	Recommended wattage	IP rating needed
Sleeping area / overcab bed	2700K warm white	250-350 lm/m	8W/m	IP20
Lounge / dinette seating	2700K-3000K warm white	300-500 lm/m	8-10W/m	IP20
Kitchen worktop	4000K natural white	700-900 lm/m	12-14W/m	IP20
Bathroom / washroom	3000K-3500K	400-600 lm/m	10W/m	IP67 minimum
Awning / exterior	2700K-3000K warm white	400-600 lm/m	10W/m	IP67 minimum
Storage / garage area	4000K-5000K cool white	500-700 lm/m	10-12W/m	IP20 or IP65

A practical approach for most 2026 conversions: order two reels — one warm white (2700K or 3000K) for living spaces and one natural white (4000K) for the kitchen. ATOM LED's cut to length at marked intervals means you cut each reel to the exact length you need without wasting material or voiding the 5-year warranty.

One critical note on colour: if you want colour-changing RGB lighting for ambient effects, understand that RGB strip cannot produce a clean white. It produces a cold, violet-tinged white that most people find uncomfortable for extended use. If you want both colour effects and proper white light, you need RGBW strip with a dedicated white channel. See our LED controllers range for compatible options.

How far can you run 12V LED strip before voltage drop becomes a problem?

On 12V strip at 10W/m, voltage drop becomes visible to the eye at approximately 4-5 metres from the feed point. At 6 metres, you can expect 8-12% brightness reduction at the far end. For a typical motorhome requiring 6-8 metres total, split the strip into two or three parallel runs fed from a central point to keep brightness uniform throughout.

Voltage drop is the single biggest technical challenge with 12V LED strip in motorhomes. It happens because the thin copper traces on the strip have measurable resistance — the further current travels along the strip, the more voltage is lost as heat. At 12V, you have very little headroom before the LEDs at the far end start dimming visibly.

Here is a practical voltage drop reference for ATOM LED 12V COB strip:

• 8W/m strip, 3m run: Approximately 2-3% drop — not visible to the eye. Single feed is fine.
• 10W/m strip, 4m run: Approximately 4-6% drop — borderline visible in a dark motorhome. Single feed acceptable for most users.
• 10W/m strip, 5m run: Approximately 7-9% drop — visible difference between start and end. Consider parallel wiring.
• 10W/m strip, 6m run: Approximately 8-12% drop — noticeable. Split into two 3m parallel runs.
• 14W/m strip, 5m run: Approximately 10-15% drop — requires parallel wiring or mid-point feed.

The fix is simple: instead of running one continuous 6-metre length from a single feed point, run two 3-metre lengths in parallel from a central junction. Each length sees only half the distance, so voltage drop stays below 5%. This is standard practice in professional motorhome conversions and adds only a few pounds in additional wiring cost.

What IP rating do you need for motorhome wet areas?

For motorhome bathrooms, shower cubicles, and any area subject to direct water contact, you need IP67-rated LED strip as a minimum. IP65 is rated for surface splash only and will not survive the humidity and direct water exposure typical in a motorhome washroom. For exterior awning lighting, IP67 provides adequate protection for most UK conditions in 2026.

IP ratings in motorhomes follow different rules to domestic bathrooms. A motorhome washroom is a much smaller, more enclosed space with higher condensation levels. Combined with road vibration that can work moisture into enclosures over time, the demands on waterproofing are higher than a typical house bathroom.

• IP20 (no water protection): Suitable for dry interior zones only — overhead cabinets, lounge area ceilings, under-shelf lighting in wardrobes. This is where most of your strip will be installed.
• IP65 (surface splash): Suitable for kitchen areas where occasional splashes occur, but NOT for bathrooms or exterior use. IP65 silicone coating does not withstand sustained humidity or direct water contact.
• IP67 (temporary immersion rated): The correct minimum for motorhome washrooms, exterior awning runs, and any area subject to condensation or direct water. ATOM LED supplies IP67-rated COB strip in 12V across multiple colour temperatures.
• IP68 (continuous submersion): Required only if you are installing strip in areas subject to standing water — rare in motorhome applications but used in some bespoke shower floor installations.

A practical layout for a typical coachbuilt motorhome: IP20 strip for the lounge, bedroom, kitchen ceiling, and wardrobe lighting (approximately 70% of your total strip length). IP67 strip for the washroom and any exterior awning runs (approximately 30%). This keeps costs down while ensuring waterproofing where it actually matters.

Browse our outdoor-rated COB strip lights for the full range of IP67 and IP68 options suitable for motorhome wet areas and exterior applications.

COB vs SMD strip lights — which is better for motorhome interiors?

COB (Chip-on-Board) strip produces a continuous, dot-free line of light with no visible LED hotspots. SMD strip uses individually spaced LED chips that create a dotted pattern visible through most diffusers. For motorhome interiors in 2026, COB strip is the better choice — it produces cleaner, more uniform light in the close-viewing distances typical of a compact living space.

In a house, you view most LED strip from 2-3 metres away. In a motorhome, you are typically 30-80 centimetres from the strip. At that distance, the individual LED dots on SMD strip (even high-density 120 LED/m SMD2835) are clearly visible and produce an uneven, spotted light pattern on adjacent surfaces. COB strip eliminates this entirely because the LED chips are embedded directly into the substrate, producing one continuous light source.

• Light uniformity: COB produces zero visible hotspots. SMD produces visible dots at close range — a persistent annoyance in a motorhome where you cannot increase viewing distance.
• CRI (colour rendering): ATOM LED COB strip is CRI90+ across all colour temperatures. Most SMD strip on the market sits at CRI80 or lower. In a motorhome kitchen, the difference between CRI80 and CRI90 is immediately visible when preparing food.
• Heat output: COB strip distributes heat more evenly along its length compared to SMD, which concentrates heat at each LED chip. This matters in motorhomes where enclosed spaces trap heat.
• Flexibility: COB strip bends more smoothly around gentle curves — useful for curved motorhome ceiling panels and radius corners.
• Power consumption: Comparable at equivalent brightness levels. A 10W/m COB strip and a 10W/m SMD strip draw the same current from your leisure battery.

The one scenario where SMD still makes sense is if you need addressable, individually controllable LEDs for animated lighting effects (running light patterns, colour chasing). For that application, see our addressable digital RGB COB strip. For all standard motorhome interior lighting, COB is the better technology in 2026.

How much power do motorhome LED strip lights draw from a leisure battery?

A typical 5-metre motorhome interior installation using 12V COB strip at 10W/m draws 4.17 amps. On a 100Ah leisure battery, that provides approximately 24 hours of continuous use — or roughly 5-7 evenings of normal 3-4 hour use before recharging. LED strip is one of the lowest-drain electrical loads in a modern leisure vehicle.

Understanding battery drain matters because motorhome owners frequently wild camp or use sites without hookup. Here is a practical power calculator for common ATOM LED 12V strip configurations:

• 5m of 8W/m strip: Total 40W / 12V = 3.33A draw. On 100Ah battery = approximately 30 hours continuous.
• 5m of 10W/m strip: Total 50W / 12V = 4.17A draw. On 100Ah battery = approximately 24 hours continuous.
• 8m of 10W/m strip: Total 80W / 12V = 6.67A draw. On 100Ah battery = approximately 15 hours continuous.
• 10m of 10W/m strip (large motorhome): Total 100W / 12V = 8.33A draw. On 100Ah battery = approximately 12 hours continuous.
• 5m of 14W/m strip (high output): Total 70W / 12V = 5.83A draw. On 100Ah battery = approximately 17 hours continuous.

In practice, you will rarely have all zones lit simultaneously. Most motorhome owners use 2-3 zones at once during an evening — lounge and kitchen, or bedroom and bathroom. A realistic evening draw for a well-planned 2026 installation is 2-4 amps for 3-4 hours, consuming 6-16Ah per evening. Even a modest 85Ah leisure battery handles that comfortably for 5-7 days without hookup.

Compare this to a typical halogen downlight installation: four 20W halogen spots draw 6.67A for the equivalent of approximately 15 hours on a 100Ah battery — producing less light, more heat, and an inferior colour rendering. LED strip is not only brighter and more flexible, it dramatically extends your off-grid capability.

How do you connect LED strip lights to a motorhome electrical system?

Connect 12V LED strip to your motorhome's existing 12V lighting circuit via the fuse board — typically a Sargent EC155 or EC500, or a Schaudt EBL 99/211. Use a fused spur (3A or 5A blade fuse) from a spare lighting output, run 1.0mm or 1.5mm twin-core automotive cable to the strip location, and connect using soldered joints or quality crimp connectors. Never use domestic wiring methods in a 12V vehicle system.

The exact connection method depends on your motorhome's power distribution unit. Here are the two most common setups found in UK motorhomes in 2026:

Sargent power units (Bailey, Swift, Elddis, Lunar)

• Locate the spare fused output: Sargent EC units typically have 1-3 spare fused outputs on the lighting bus. Check your unit's manual for the labelling.
• Select the correct fuse: Calculate total strip wattage, divide by 12V, and select a blade fuse rated at 150% of that current. For a 5m run at 10W/m: 50W / 12V = 4.17A — use a 5A or 7.5A fuse.
• Run cable: Use 1.5mm twin-core automotive cable for runs over 3 metres. Use 1.0mm for runs under 3 metres with loads under 4A.
• Terminate at the strip: Solder connections to the strip's copper pads, or use ATOM LED's solderless connectors from our accessories range.

Schaudt EBL units (Hymer, Dethleffs, some Rapido)

• Identify a spare circuit: Schaudt EBL 99 and EBL 211 units provide numbered lighting outputs. Refer to the unit schematic — typically output L1-L6 for lighting.
• Follow the same fuse and cable sizing: Identical principles to Sargent — fuse at 150% of calculated current, automotive-grade cable throughout.
• Earth return: Schaudt units typically use a common negative bus bar. Connect your strip's negative return to this bus, not to a random chassis point.

Critical wiring rules for motorhome LED installations:

• Always use parallel wiring for multiple strip runs: Never wire strip runs in series. Series wiring multiplies voltage drop and creates uneven brightness across zones.
• Never tap into the vehicle starter battery circuit: The leisure battery is isolated from the vehicle battery for a reason. Connecting lighting to the starter circuit risks draining it and leaving you unable to start the engine.
• Use automotive-grade connectors throughout: Domestic chocolate block connectors vibrate loose within weeks. Use crimp ring terminals, blade connectors, or solder all joints.
• Route cables away from heat sources: Keep wiring clear of engine bay bulkheads, exhaust runs, and heating system ducting.
• Label every circuit: Future maintenance (or the next owner) will thank you. Label at the fuse board and at each strip connection point.

If you are unsure about any aspect of connecting to your specific motorhome's electrical system, call ATOM LED's technical team on 01952 370028 or email operations@atomled.co.uk. We support motorhome converters and self-builders across the UK with wiring advice specific to your power distribution unit.

Why does standard adhesive fail in motorhomes — and how do you fix it?

Standard 3M VHB adhesive tape on LED strip fails in motorhomes because of three combined stresses that do not exist in static domestic installations: continuous road vibration, temperature cycling from -5C to 40C+ inside a parked vehicle, and surface condensation on plastic and metal panels. The fix is aluminium profiles with mechanical screw-mount clips — they hold permanently regardless of vibration or temperature.

This is one of the most common complaints we hear from motorhome owners who have tried sticking strip lights directly to surfaces. The adhesive typically holds for 2-6 weeks during summer use, then starts peeling from one end. By autumn, entire sections are hanging loose.

The underlying physics is clear:

• Vibration: A motorhome in motion produces constant low-frequency vibration across every surface. This creates micro-shear forces at the adhesive bond line that slowly break the tape free. Static installations never experience this.
• Temperature cycling: A parked motorhome in summer can reach 40-50C internally, then drop to 5-10C overnight. This expansion-contraction cycle stresses the adhesive bond differently on each surface material. Over weeks, it delaminates.
• Surface compatibility: Many motorhome interior panels use melamine-faced ply, GRP (fibreglass), or textured ABS plastic. These surfaces have lower adhesion properties than the smooth plasterboard or tile surfaces adhesive tape is designed for.

The professional solution: aluminium profiles with mechanical fixings.

• Screw-mount aluminium profile: Fix the profile to the motorhome structure using self-tapping screws (pre-drill to avoid cracking GRP panels). The strip sits inside the profile channel, held by its own adhesive against the flat aluminium surface — which actually bonds well because aluminium provides an excellent adhesion surface.
• Clip-mount profile: For locations where screw holes are not acceptable, use profiles with spring clips that grip into a routed channel or pre-made slot.
• Curved surface profiles: Motorhome ceilings often have compound curves. ATOM LED's flexible silicone profiles conform to these curves while still providing a stable mounting surface. See our silicone profile range for options that bend to radius corners.

Browse the full range of aluminium LED strip profiles including surface-mount, recessed, and corner options suitable for motorhome installations. All profiles accept standard ATOM LED COB strip and include frosted diffuser covers that soften the light output and protect the strip from physical contact.

Can you dim 12V LED strip lights in a motorhome?

Yes — 12V LED strip dims effectively using a PWM (Pulse Width Modulation) dimmer connected between the power source and the strip. Do not use domestic trailing-edge or leading-edge AC dimmers — these are designed for mains voltage and will not work with 12V DC. A simple in-line 12V PWM rotary dimmer or touch dimmer costs under 10 pounds and provides smooth, flicker-free control from 0-100%.

Dimming is particularly valuable in motorhomes because you often want bright task lighting while cooking, then much softer ambient lighting during the evening. A per-zone dimmer lets you achieve both without installing separate circuits.

• In-line 12V PWM dimmer: The simplest option. Wire it between the fuse board output and the strip. A rotary knob or touch pad controls brightness. Suitable for single-colour strip only.
• 12V RF remote dimmer: Adds wireless control — convenient when the dimmer switch is not within easy reach from a seating position. Range is typically 10-15 metres, more than enough for any motorhome.
• Multi-zone controller: If you have 3-4 separate strip circuits (lounge, kitchen, bedroom, bathroom), a multi-zone 12V controller lets you dim each independently from a single handset. Browse our full controller range for compatible 12V options.

Important: RGB and RGBW strip dimming works differently. RGB and RGBW strip must use a dedicated RGB/RGBW controller — never a standard dimmer. These strips require a non-dimmable constant voltage power source with the controller handling colour mixing and brightness. Using a dimmable driver or standard dimmer with RGB/RGBW strip causes flicker, colour shift, and premature failure of both the strip and the controller.

For single-colour 12V strip in a motorhome, dimming is simple, affordable, and strongly recommended. Contact ATOM LED on 01952 370028 if you need help selecting the right dimmer for your zone layout.

What wattage per metre do you need for each motorhome area?

For primary ambient lighting in a motorhome lounge or bedroom, 8-10W/m provides comfortable general illumination. Kitchen task lighting needs 12-14W/m for clear visibility over worktops. Accent and mood lighting in display cabinets or toe-kicks only needs 4-6W/m. Match the wattage to the task — over-specifying wastes battery power, under-specifying leaves you reaching for a head torch.

Wattage per metre directly determines brightness (measured in lumens per metre) and power draw from your leisure battery. In a motorhome, the goal is to use the minimum wattage that provides adequate light for each zone, because every extra watt shortens your off-grid time.

• Accent and display lighting (4-6W/m): Shelf displays, toe-kick under cabinets, wardrobe interiors, decorative coving. Provides a soft glow rather than functional illumination. Battery-friendly for overnight use.
• General ambient lighting (8-10W/m): Main ceiling runs in lounge, bedroom, and dinette areas. Provides comfortable general light equivalent to a well-lit room. This is where most of your strip length will be specified.
• Task lighting (12-14W/m): Kitchen worktops, bathroom mirror area, reading lights. Provides focused, bright light for detailed tasks. Use shorter runs at higher wattage rather than long runs at low wattage.

A typical panel van conversion in 2026 might use: 3 metres of 10W/m warm white in the living area (30W total), 1 metre of 14W/m natural white over the kitchen (14W total), 0.8 metres of 10W/m warm white in the bathroom (8W total), and 1.5 metres of 6W/m warm white for accent lighting (9W total). Total system load: 61W / 12V = 5.08A. That is modest, manageable, and leaves plenty of battery capacity for other appliances.

ATOM LED's cut to length at marked intervals means you cut each strip to the exact length needed — no waste, no paying for strip you do not use. Every cut point maintains the full 5-year warranty.

How do you install LED strip lights in a motorhome step by step?

Installing LED strip in a motorhome follows the same core process as any domestic installation, with three additional requirements: mechanical fixing instead of adhesive-only mounting, automotive-grade wiring and connectors throughout, and fuse protection at the power distribution board. A competent DIYer with basic 12V wiring experience can complete a full motorhome strip installation in a day.

1. Plan your zones and measure precisely: Walk through the motorhome and mark each strip location with masking tape. Measure each run to the nearest 50mm. Note which zones need IP20 (dry) and which need IP67 (wet). Record the total length per colour temperature.
2. Calculate total power draw: Multiply each run length by its wattage per metre. Add all zones together. Divide total watts by 12 to get total amps. This determines your fuse rating and cable gauge. For example: 8 metres total at 10W/m = 80W / 12V = 6.67A.
3. Install aluminium profiles first: Fix profiles to the mounting surface using appropriate screws for the substrate — self-tapping for wood, with pre-drilled pilot holes for GRP. Use a spirit level on horizontal runs. Allow 10mm clearance at each end for wiring access.
4. Run wiring from the fuse board to each zone: Use 1.5mm twin-core automotive cable for runs over 3 metres or loads over 4A. Use 1.0mm for shorter, lighter runs. Route cables through existing cable channels where possible. Secure with P-clips at 300mm intervals — never use cable ties as the sole fixing.
5. Cut strip to length and solder connections: Cut ATOM LED COB strip at any point along the strip — cut to length at marked intervals means every cut point is a valid termination. Solder 18AWG silicone wire to the copper pads, or use solderless snap connectors from our accessories range. Apply heat-shrink tubing over every exposed connection.
6. Mount strip into profiles: Peel the adhesive backing and press the strip firmly into the aluminium profile channel. The flat aluminium surface provides a strong adhesive bond. Fit the frosted diffuser cover.
7. Connect to the fuse board: Wire each zone to a fused output on the Sargent or Schaudt unit. Install the correct blade fuse — 150% of calculated current draw. If using a dimmer, wire it in-line between the fuse board output and the strip feed cable.
8. Test each zone individually: Power on one zone at a time. Check for even brightness along the full length (uneven brightness indicates a wiring fault or cold solder joint). Check dimmer operation if fitted. Check IP67 strip connections for any exposed wiring near wet zones.
9. Final checks and labelling: Verify total current draw with a multimeter at the fuse board — it should match your calculation within 10%. Label each fuse with the zone name. Photograph the complete wiring layout for future reference.

Warning: never power LED strip while it is still coiled on the reel. The heat generated by the strip has no way to dissipate when coiled, which destroys the adhesive, damages the LEDs, and creates a fire risk. Always uncoil and mount before powering on.

Warning: never mount strip directly on bare metal surfaces without insulation. The exposed copper pads on the strip's underside can short-circuit against conductive metal surfaces, damaging the strip and potentially blowing the fuse. Always mount inside an aluminium profile (which has an anodised insulating layer) or apply a thin insulating strip beneath.

Frequently asked questions — motorhome and caravan LED lighting

Can I connect 12V LED strip directly to my motorhome leisure battery?

• Yes, but not directly to the battery terminals. Connect via the fuse board (Sargent, Schaudt, or aftermarket) using a fused spur.
• Always fuse the circuit at 150% of calculated current draw — for example, a 5A fuse for a 3.33A load.
• Never connect lighting to the vehicle starter battery — use the leisure battery circuit only.

Will 12V LED strip work on a 12.8V lithium leisure battery?

• Yes. 12V LED strip operates across a 10V-14V input range. Lithium batteries typically sit at 12.8V-13.2V, which is within the operating range of all ATOM LED 12V strip.
• Lithium batteries maintain higher voltage under load than lead-acid, so brightness will be marginally more consistent across the discharge cycle.

Do I need a separate driver or transformer for 12V strip in a motorhome?

• No. A 12V strip running from a 12V leisure battery does not need a driver or transformer — the battery is the power source.
• Drivers and transformers convert mains 240V AC to DC voltage. In a motorhome, your leisure battery already provides 12V DC, so no conversion is needed.
• You only need a driver if using 240V hookup to power the strip through the mains circuit — in which case use a 12V constant voltage driver from our power supply range.

How many metres of LED strip do I need for a motorhome conversion?

• Panel van conversion (SWB): Typically 4-6 metres total across all zones.
• Panel van conversion (LWB): Typically 6-9 metres total.
• Coachbuilt motorhome (6m): Typically 8-12 metres total.
• Large A-class or tag-axle: Typically 12-18 metres total.
• Touring caravan: Typically 5-8 metres total depending on layout.

Is 12V LED strip safe to install in a motorhome without an electrician?

• 12V DC lighting does not fall under Part P of the Building Regulations and does not require a qualified electrician for installation in a leisure vehicle.
• Basic competence with 12V automotive wiring is needed — soldering or crimping, fuse selection, correct cable sizing, and polarity awareness.
• If you are not confident, ATOM LED's technical team can talk you through the process on 01952 370028 or via email at operations@atomled.co.uk.

Can I use LED strip under an awning or outside the motorhome?

• Yes — use IP67-rated strip for awning and exterior applications. IP67 handles rain, condensation, and typical UK outdoor conditions.
• Mount in an aluminium profile with a sealed diffuser to add mechanical protection against knocks and UV exposure.
• Use a Waterproof connector at the point where the cable exits the motorhome body to prevent water ingress along the cable route.

What is CRI and why does it matter in a motorhome?

• CRI (Colour Rendering Index) measures how accurately a light source shows true colours on a scale from 0 to 100. Sunlight scores 100.
• CRI90+ (all ATOM LED COB strip) means food looks natural, skin tones are accurate, and interior furnishings appear as the designer intended.
• CRI80 or below (most budget strip) gives food a grey cast, makes wood grain look flat, and creates an uninviting atmosphere — noticeable in the compact space of a motorhome interior.

Will LED strip lights drain my battery when the motorhome is not in use?

• LED strip has zero standby drain when switched off at the fuse board or via a physical switch.
• If using a wireless controller or dimmer with standby mode, the controller may draw 0.01-0.05A — negligible over a few weeks but worth switching off via the master battery isolator for long-term storage.
• Always use the habitation battery isolator when storing the motorhome for more than 2 weeks.

Can I fit colour-changing LED strip in my motorhome?

• Yes — use 12V RGBW strip with a dedicated RGBW controller. The controller handles colour mixing and brightness.
• Do not use a standard dimmer or dimmable driver with RGBW strip — this causes flicker, colour shift, and premature component failure.
• If you want clean white light as well as colour effects, choose RGBW (not RGB alone). RGB strip produces a violet-tinged white that is uncomfortable for extended use as primary lighting.

What is cut to length at marked intervals and why does it matter for motorhome strip?

• cut to length at marked intervals means you can cut ATOM LED COB strip at any point along its length — not just at fixed intervals like traditional SMD strip.
• This eliminates waste when fitting to exact motorhome dimensions — you cut to the millimetre, not the nearest 50mm or 100mm.
• Cutting does not void the 5-year warranty. Every cut point is a valid termination with full copper pad access for soldering or connector attachment.
