Buying LED strips: a guide to choosing the right lights for your home, smart home and car

LED strips create indirect lighting behind your TV, under kitchen cabinets, in a gaming room or inside your car. Choosing one may seem straightforward at first: pick the length and colour, choose a remote control, stick it on and switch it on. In practice, however, a few common buying mistakes can lead to unnecessary extra costs.

Common pitfalls when buying LED strips

1. RGB doesn’t automatically mean individually controllable lighting

A standard RGB LED strip usually displays one colour along its entire connected length. RGBIC models, on the other hand, can show different colours in several sections at the same time. If you’re looking for chasing effects, colour gradients or segmented patterns, check specifically for terms such as RGBIC, Smart IC or segmented control.

2. The IP rating is overlooked for unsuitable locations

Many LED light strips for living spaces have an IP20 rating. This means they’re intended for dry indoor areas and offer no protection against water. For a bathroom, balcony or other damp area, you’ll need a product with a suitable IP rating. A coated LED strip isn’t automatically suitable for outdoor use, either.

3. The length, power supply and mounting surface don’t match

A 5-metre LED strip needs enough space as well as a suitable power supply. If you use the strip while it’s tightly wound, heat can build up. With longer installations, brightness and colour may also vary towards the end of the strip. The surface should be clean, dry and as smooth as possible. Adhesive strips may not hold as securely on porous walls or dusty furniture backs.

The key things to consider when buying LED lighting

Voltage and power supply

Before buying, check the stated operating voltage. A model that runs on 24 V DC must not be connected to an unsuitable power source. LED strips for vehicles, by contrast, are often designed for a 12 V supply. The power supply should match the strip’s power consumption and be used only as described in the product information.

LED density and light effect

The number of LEDs per metre affects how evenly the strip appears to glow. For example, a standard 5-metre LED strip with 150 LEDs has 30 LEDs per metre. For ambient lighting behind a TV, a decorative glow is often enough. If you want to light a shelf, worktop or cabinet, brightness, distance from the edge and colour temperature matter more.

Controls and installation

An LED strip with remote control is ideal for simple colour and brightness adjustments. App control, Wi-Fi, Bluetooth and Matter are better suited to smart home users. LED lighting with music control usually uses a microphone or audio signal to make the colours change in response to sound. It’s a feature for creating atmosphere, rather than precisely synchronising with every beat of a song.

Also consider:

  • Bend radius: Don’t bend LED strips sharply.
  • Cutting points: Cut only at the marked points.
  • Mounting surface: Degrease the surface before installation and let it dry completely.
  • Heat dissipation: Don’t leave the strip switched on while it’s still on the reel.
  • Indoor or outdoor use: IP20 products are for dry indoor spaces.
  • Vehicle installation: Lights must not obstruct your view, controls or road safety.

LED strip FAQs

How long do LED strips last?

Their actual lifespan depends on factors such as how long they’re used, heat dissipation, the power supply and installation. Don’t leave an LED strip switched on while it’s rolled up, or bend it too sharply. For models with an adhesive backing, installing it on a clean, dry surface will help the adhesive last longer.

How much electricity does an LED strip use?

Consumption depends on the strip’s power rating and how long you use it each day. A 24 W model uses 0.024 kWh for one hour of operation. To calculate the running cost, multiply this figure by your electricity tariff and the number of hours it’s used. Control boxes may still draw a small amount of power in standby mode.

Can you cut an LED strip to size?

Many LED strips can be cut at the marked points. Before doing so, check whether you’ll need a new connector or a suitable joining piece afterwards. Cutting outside the marked points can damage individual sections. If your vehicle kit includes several separate sections, make sure you also follow the recommended wiring layout.
