Buying LED strip lights: a guide for living rooms, gaming, smart homes and cars

LED strips are ideal for creating indirect lighting behind the television, under shelves, at your desk or in your vehicle. Before you buy, though, it’s worth checking the technical details carefully. Terms such as RGB, music synchronisation and ‘smart control’ don’t automatically mean a product is right for every use.

Common pitfalls when buying LED strips

1. Unclear information about length and power supply

A five-metre LED strip doesn’t necessarily need the same power supply as a two-metre model. The key factors are voltage, power consumption and the maximum length supported by the power supply. If you connect several strips, the light may become dimmer towards the end, or the power supply could become overloaded.

Also check whether a power supply, controller or remote control is included. Battery-powered options have different running costs from an LED light strip that plugs into the mains.

2. RGB is mistaken for even, functional lighting

An RGB LED strip can display different colours, but it’s not necessarily suitable for practical room lighting. Many RGB products create coloured accent lighting, while a warm white LED light strip at 3000 K may be a better choice for shelves, furniture or subtle background lighting.

The construction also affects the light. COB technology can create a more continuous line of light, while individual SMD LEDs may appear as visible points, depending on their spacing.

3. Protection rating and mounting surface are overlooked

A product rated IP20 is designed for dry indoor spaces. For a bathroom, balcony or outdoor area, make sure the stated protection rating is suitable for where you plan to use it. A coating alone doesn’t automatically mean an LED strip is permanently waterproof.

The adhesive will also only hold reliably on a clean, dry and smooth surface. Dust, grease, rough walls and sources of intense heat can all affect how well it sticks. In vehicles, you’ll also need to account for vibration, temperature changes and a suitable power supply.

Technical details to compare

Voltage and power consumption

Common systems use 12 V or 24 V DC, for example. The LED strip’s voltage must match the power supply and controller. A 24 V model must not be connected to an unsuitable 12 V supply.

Power consumption is measured in watts. According to the product details, a two-metre Aigostar model runs at 24 V, 18 W and 0.75 A. The supplied power adapter is designed for this combination. If you extend the strip, don’t exceed the maximum length specified by the manufacturer.

Light colour, brightness and colour rendering

Colour temperature is measured in kelvin:

  • Warm white, around 2700 to 3000 K: suitable for living rooms, bedrooms and subtle decorative lighting.
  • Neutral white, around 4000 K: gives a more practical feel and may be a good choice for work areas.
  • RGB or RGBIC: for colourful scenes, gaming set-ups, party rooms and decorative LED lighting.

Lumens indicate the amount of light produced. A higher lumen rating doesn’t automatically mean more comfortable lighting, though. Beam angle, mounting position and the effect you want to create are also important. The Aigostar COB LED strip is listed as producing 1800 lumens, 3000 K and Ra ≥ 80.

Controls and compatibility

An LED strip with a remote control is easy to use, but usually needs a clear line of sight to the receiver. An LED strip with app control lets you set scenes, timers or brightness levels from your smartphone. Before buying a smart LED strip, check whether it requires Bluetooth, Wi-Fi, Matter or a specific app.

Features such as music synchronisation usually rely on a microphone or an audio connection. How well they respond can therefore depend on the volume, the distance from the sound source and the app you use. RGBIC systems can also control several colour zones at once, while a traditional RGB strip often displays just one colour along its entire length.

Why this product suits you: This warm white LED light strip is suitable for dry indoor spaces, such as under wall units, on shelves or as indirect lighting in the living room.

How this product avoids the pitfall

The COB technology, 24 V rating, IP20 rating and recommendation for dry indoor use are all clearly stated. Only cut the strip at the marked cut points.

Key benefits and features

Plan the installation and use carefully

Measure the area before you buy, and bear in mind that the strip shouldn’t be folded sharply around corners. Cut LED strips only at the marked cut points. Make sure the power is switched off and the polarity is correct when connecting the strip.

Don’t leave a coiled strip running for long periods. The heat generated can put strain on the electronics and adhesive. A soft, dry cloth is all you need for cleaning. Stop using the strip if you notice cracks, discolouration, smoke or unusual noises.

FAQs about LED strips

How long do LED strips last?

Their lifespan depends on LED quality, heat dissipation, how long they’re used and how they’re installed. For example, an Aigostar model is listed as lasting up to 20,000 hours. This is a manufacturer’s estimate, not a guarantee for every installation.

How much electricity does an LED strip use?

It depends on the strip’s length, LED density, brightness and colour. An 18 W model running at full power uses 0.018 kWh per hour. It may use less when dimmed. To work out the running cost, multiply the power in kilowatts by the daily hours of use and your electricity rate.

Can LED strips be used outdoors?

Only if the specific product has a suitable IP rating and the power supply and connections are also installed with adequate protection. An LED strip rated IP20 is designed for dry indoor spaces and shouldn’t be used outdoors, in a bathroom or anywhere it could be exposed to splashing water.
