Best 12V LED Strip Lights for Campervans: Complete Installation Guide
LED strip lights are the most popular lighting choice for campervan conversions. They are cheap, flexible, low-power, and create the warm, diffuse lighting that makes a van feel like home. But cheap strips fail, colours are inconsistent, and adhesive backing does not hold in a van's temperature swings.
This guide covers the LED strip options, power consumption, installation, and how to make your van lighting look professional.
LED Strip Types
| Type | Colour | CCT | Power/Metre | Best For |
|---|---|---|---|---|
| Warm white | Single colour | 2700–3000K | 4.8–9.6W/m | General living, bedroom |
| Cool white | Single colour | 4000–5000K | 4.8–9.6W/m | Kitchen task lighting |
| Daylight white | Single colour | 6000K | 4.8–9.6W/m | Reading, workshop |
| RGB | Multi-colour | N/A | 7.2–14.4W/m | Accent lighting, mood |
| RGBW | Multi-colour + white | 3000K + RGB | 14.4W/m | Mood + functional |
| Tunable white | Adjustable CCT | 2700–6500K | 9.6–14.4W/m | Best of all, but more expensive |
LED Density
| Density | LEDs/m | Power/m | Light Quality | Best For |
|---|---|---|---|---|
| 30 LEDs/m | Low | 4.8W/m | Visible dots at close range | Accent only |
| 60 LEDs/m | Medium | 9.6W/m | Smooth, no dots at arm's length | General lighting |
| 120 LEDs/m | High | 14.4W/m | Perfectly smooth | Task lighting, professional finish |
| 144 LEDs/m | Very high | 19.2W/m | Brightest, smooth | Large areas |
Recommendation: 60 LEDs/m warm white (3000K) for general living areas. 120 LEDs/m cool white (4000K) for the kitchen. This gives a warm, inviting main area and bright, clear task lighting.
Power Consumption
| Strip Type | Power/Metre | 5 Metres | Daily Use (4 hours) | Annual Cost (25p/kWh) |
|---|---|---|---|---|
| 30 LEDs/m (low) | 4.8W | 24W | 96Wh | £8.76 |
| 60 LEDs/m (standard) | 9.6W | 48W | 192Wh | £17.52 |
| 120 LEDs/m (high) | 14.4W | 72W | 288Wh | £26.28 |
| RGBW (high) | 14.4W | 72W | 288Wh | £26.28 |
In van life terms: A 5-metre 60 LEDs/m warm white strip running for 4 hours uses 192Wh (16Ah at 12V). On a 200Ah LiFePO4 battery, that is 8% of usable capacity per day. LED lighting is cheap to run.

Step-by-Step
-
Plan the layout: Measure all runs. LED strips can be cut at marked intervals (every 3–5 LEDs). Plan for the controller location and power source.
-
Mount the aluminium channel: The channel provides heat dissipation (LEDs generate heat and dim over time without heatsinking) and a professional look (the strip is recessed and diffused). Stick the channel to the ceiling or cabinet underside with VHB tape or screws.
-
Cut the LED strip to length: Cut at the marked cut lines. Use sharp scissors. Do not cut through the copper pads.
-
Solder or use connectors: Soldering creates the most reliable connection. For the quick option, use clip-on 2-pin or 4-pin connectors — but these can fail in hot/cold cycling.
-
Connect the strip to the controller: RGB and RGBW strips need 4-pin connectors (one common positive + three/four colour channels). Single-colour strips need 2-pin (positive + negative).
-
Connect the controller to 12V power: Run 1.5mm² cable from the controller to a 5A fused circuit in the fuse box.
-
Install a switch: Between the controller and the LED strip. A dimmer switch is recommended.
-
Test before final mounting: Connect everything, turn on the power, check all colours/brightness levels work.
-
Mount the strip in the channel: Remove the backing tape, press the strip into the channel. Fit the diffuser cover.
Dimmers
| Dimmer Type | Cost | Works With | Installation |
|---|---|---|---|
| PWM rotary knob | £5–10 | Single-colour strips | In-line, simple |
| PWM touch dimmer | £10–15 | Single-colour strips | Wall-mounted |
| RF remote + receiver | £10–20 | RGB and single-colour | Remote control |
| WiFi controller | £15–30 | RGB and single-colour | Smartphone control |
| Hardwired 0-10V | £20–40 | Professional strips | More complex |
Recommendation: A PWM rotary knob dimmer for warm white strips. It is simple, cheap, and reliable. Avoid touch dimmers in damp environments (kitchen) — they can be unreliable when wet.
Common Installation Mistakes
-
No aluminium channel: LEDs overheat without heatsinking, causing colour shift and early failure. The channel also diffuses the light, eliminating the "dotty" look.
-
Adhesive tape only: The 3M tape on LED strips fails in van temperatures (30°C+ in summer, −5°C in winter). The strip droops after 6 months. Use aluminium channel + clips.
-
Undersized cable: 1.5mm² minimum for any LED strip run. Longer runs (5m+) benefit from 2.5mm² to reduce voltage drop — the far end of a long strip can be noticeably dimmer.
-
Voltage drop on the strip itself: Running more than 5m of LED strip from a single power feed causes the far end to be dimmer than the near end. For longer runs, power-inject at both ends or use higher voltage (24V strips).
-
Wrong controller for the strip type: RGB strips need RGB controllers. Single-colour strips need single-channel dimmers. A single-colour dimmer on an RGB strip turns all colours on/off but cannot change colours.
12V vs 24V LED Strips
| Voltage | Pros | Cons |
|---|---|---|
| 12V | Direct from leisure battery, no converter | Voltage drop over 5m+, needs power injection |
| 24V | Lower current, less voltage drop, runs 10m+ | Needs 24V → 12V converter for other devices |
| 5V (USB) | Can use power banks | Very low power, short runs only |
For a 12V campervan electrical system, 12V strips are the obvious choice. 24V strips need a 24V converter, adding cost and complexity.

FAQ
Q: How many LED strip lights do I need for a campervan? A: For a typical Transit Custom (5.3m), install 3–4 metres of warm white (general lighting, along the roof line or in channels) and 1 metre of cool white (kitchen task lighting, under cabinets). This provides equivalent light to a 60W household bulb.
Q: Can I connect multiple LED strips to one controller? A: Yes, if the total power draw does not exceed the controller's rating. Most controllers are rated for 5–10 metres total. For longer runs, use a higher-rated controller or power-inject at the far end.
Q: How do I stop LED strips flickering? A: Flickering is caused by: incompatible dimmer (PWM frequency too low), insufficient power supply, or voltage drop. Use a quality PWM dimmer (1kHz+), ensure the power supply is rated for at least 20% more than the strip's consumption, and use adequate cable.
Q: Can I dim LED strip lights without a special dimmer? A: No. Standard light dimmers (household rotary dimmers) are designed for mains voltage and resistive loads. They do not work with LED strips. You need a PWM (pulse-width modulation) dimmer designed for 12V LED strips.
Q: How long do LED strips last in a campervan? A: Quality LED strips (with aluminium channel for heat dissipation) last 20,000–30,000 hours. At 4 hours per day, that is 14–20 years. Cheap strips without heatsinking fail in 6–24 months.
Q: Can I cut LED strips to custom lengths? A: Yes. Most 12V LED strips have marked cut lines every 3–5 LEDs (every 2.5–5cm). Cut at the marked line only. Cutting elsewhere damages the circuit and kills that section.
