Buying LED Strip Lights: A Guide for Your Home, Smart Home and Car

LED strip lights are ideal for adding indirect lighting to furniture, behind your TV, under kitchen cupboards or in your gaming setup. They’re also often used inside cars. The choice ranges from simple warm white LED strips to smart LED strips with app control, voice commands and multi-colour effects.

However, product descriptions can vary considerably when it comes to length, power supply, installation and intended use. If you focus only on the number of colours or a particularly low price, you could end up with a system that doesn’t suit the area or purpose you have in mind.

Common pitfalls when buying LED strip lights

1. Misjudging the length and where you can cut the strip

A 5 m LED strip sounds versatile, but it won’t necessarily fit every wall or the space behind every TV unit. Before you buy, measure the edges you want to illuminate and consider where the power supply, control box and socket will be.

It’s also important to check whether the LED strip can be cut at the points you need. Usually, you can only cut it at the marked cutting points. Some car or multi-strip kits may have specific requirements.

2. Assuming “waterproof” means suitable for every setting

A protective coating can shield the surface from dust or minor knocks. That doesn’t automatically mean the strip is suitable for bathrooms, outdoor areas or rooms that are constantly damp. Avoid exposing indoor products rated IP20 to water or high humidity.

A coated RGBIC LED strip also needs suitable ventilation. Don’t leave it switched on while tightly rolled up for long periods, as heat can build up.

3. Confusing brightness with colour

A wide range of colours doesn’t necessarily mean a high level of illumination. RGB LED strips are designed primarily for decorative ambient lighting. For worktops, cupboards or dressing areas, a white LED light strip with a clearly stated colour temperature may be a better choice.

A warm white LED strip at around 3000 K gives off a yellower light. Cool white at around 6000 K looks more neutral to bluish and is often used in cupboards or work areas.

Key technical specifications

Power supply and electrical details

Check whether the kit uses a power adapter, USB connection, batteries or a 12-volt connection. A USB LED strip light is suitable for TVs, desks or power banks, while a 24-volt system usually needs its own power adapter.

For example, the Aigostar strip runs on 24 V DC and 18 W. According to the product details, the Govee model also runs on 24 V DC and 24 W. The power adapter and strip must be electrically compatible. Using the wrong voltage can cause faults or damage.

For vehicles, systems designed for 10 to 16 V or a 12-volt connection are more suitable. Don’t connect them to an incompatible power source.

Lighting technology: RGB, RGBIC and COB

• RGB: Red, green and blue LEDs create a range of mixed colours. Depending on the controller, the whole strip will usually display one colour at a time.
• RGBIC: Built-in control chips let you display several colour segments at once, creating gradients and flowing light effects.
• COB: A dense arrangement of light sources can create a more even line of light. The Aigostar model is listed as producing 1800 lm at 3000 K, with a colour rendering index of Ra ≥ 80.

A dimmable LED strip is handy in living rooms and bedrooms when you want to switch between subtle background lighting and a brighter accent. For practical lighting, you should also consider the stated light output.

Installation, surface and heat

The adhesive backing usually works best on clean, dry and smooth surfaces. Dust, grease and rough walls can reduce its grip. When fitting the strip around curves, guide it gently and avoid bending it directly at the LED components.

It’s a good idea to test the strip briefly before installation. On longer systems, make sure the control box and power adapter remain accessible. Don’t leave the LED strip tightly coiled while it’s in use.

Frequently asked questions about LED strip lights

How do you install an LED strip correctly?

First, measure the area, clean the surface and test the strip before sticking it in place. Only apply it to dry, smooth surfaces. Make sure the power adapter and control box remain accessible. Gentle curves work better at corners than sharp bends.

How long do LED strip lights last?

Lifespan depends on factors including how long the strip is used, heat dissipation, the power adapter and the quality of the adhesive. Figures such as “up to 20,000 hours” are manufacturers’ claims, not a guarantee for every installation. Adequate ventilation and using the correct voltage can reduce strain on the strip.

Do LED strip lights use a lot of electricity?

Energy use depends on the wattage and how long the strip is on. An 18 W strip running for one hour uses around 0.018 kWh. With RGB and RGBIC models, brightness, colour and effects can affect actual energy use. For an accurate estimate, check the wattage of the specific product and how many hours you use it each day.
