Choosing LED lighting for your home: what to look for when buying

LED lighting can enhance furniture, walls, windows and festive decorations. However, there are significant differences between a basic LED strip, an RGB LED strip and smart LED lighting when it comes to connections, light colour, controls and where they can be used. If you focus only on the number of LEDs or a high wattage, you could end up with a product that doesn’t suit the size of your room or your existing smart home setup.

Common pitfalls when buying LED lighting

1. More LEDs don’t automatically mean better lighting

The number of LEDs alone tells you little about perceived brightness or light quality. Factors such as luminous flux in lumens, the spacing between LEDs, the diffuser and the colour temperature all matter. An LED strip with lots of individual light points can have a decorative effect, while a COB LED strip can create a more uniform line of light.

2. Self-adhesive doesn’t mean it will stick to every surface permanently

A self-adhesive LED strip needs a clean, dry, grease-free surface. Adhesion may be reduced on rough walls, dusty furniture backs or silicone-based surfaces. Before fitting the strip, measure the area and unroll it fully. Using it while still coiled can cause heat to build up.

3. Smart home compatibility varies

Wi-Fi LED strips, Bluetooth products and Matter LED strips use different connection types. If you’re considering a Matter product, check that it works with your chosen system – for example, Apple Home, Google Home, Alexa, Samsung SmartThings or Home Assistant. Many Wi-Fi products also require a 2.4 GHz network. App compatibility alone doesn’t necessarily mean that every automation you want will be available.

Key factors to consider before buying

Light colour, brightness and dimming

For work surfaces or indirect lighting, lumens, colour temperature and colour rendering are all important. Warm white light around 2,700 to 3,000 K often feels more subdued, while more neutral or cooler whites up to 6,500 K create a more functional feel.

With an RGB LED strip, it’s worth distinguishing between basic RGB and RGBCCT. RGBCCT combines coloured light with separately adjustable white light. This lets you change not only the colour, but also the colour temperature. Dimmable LED lights should have a clearly stated dimming function, ideally with stepless adjustment.

Length, cut points and power supply

An LED strip needs to be the right length for the area you have in mind. For a 5-metre LED strip, the power supply needs to support the full length. You can only cut the strip at the marked cut points. Cutting it elsewhere could damage the circuit.

Check the output voltage of the power supply too. A 24-volt system must only be used with a compatible power supply. The wattage can help you estimate energy consumption, but it doesn’t replace checking the adapter supplied with the product.

IP rating and installation location

For the strips featured here, IP20 means they’re intended for use in dry indoor spaces. They’re therefore not suitable for bathrooms, outdoor areas or damp window areas unless a higher IP rating is specified. Power supplies should be left uncovered and not placed under fabrics.

The same basic rules apply to Christmas lights and decorative LED lights: check the cables, plugs and casing before use, and don’t continue using damaged products. A lit snowman or LED star should only be used in the environment specified for it.

Estimating energy use and running costs

Running costs depend on wattage, daily usage and your electricity tariff. Here’s a simple calculation:

Wattage ÷ 1,000 × hours of use × price per kilowatt-hour = cost

For example, using an 18 W light for four hours a day consumes 0.072 kWh per day. The actual cost depends on your electricity tariff. Timers and schedules can help prevent LED lighting from being left on for longer than necessary.

LED lighting FAQs

How do you fit an LED strip correctly?

First, plan the length and position, then clean the surface and let it dry. Only cut the strip at the marked points, and use a suitable power supply. With Wi-Fi models, set up the connection before fitting the strip in its final position.

How long does LED lighting last?

Lifespan depends on product quality, heat dissipation, usage time and having the correct power supply. Claims such as ‘up to 20,000 hours’ are manufacturer estimates, not a guarantee for every situation. Using the strip uncoiled and ensuring the power supply has enough ventilation will help you use it as intended.

Are LED strips suitable for outdoor use?

A product with an IP20 rating is intended for dry indoor spaces only. For gardens, balconies or damp areas, the product must explicitly have a suitable higher IP rating. If no such rating is given, don’t use the strip outdoors.
