Buying LED strips: a guide to choosing the right option for living spaces, smart homes and outdoors

An LED strip can add a targeted splash of colour to furniture, TVs, shelves or your gaming set-up. But when choosing one, the number of colours or the advertised app isn’t all that matters. Unclear information about length, IP rating and power supply can mean the LED strip won’t fit where you intended, or quickly proves impractical.

Common pitfalls when buying LED strips

1. Confusing the total length with the illuminated length

A 5 m LED strip isn’t always illuminated along its entire length. With string lights, the total length, lead-in cable and illuminated length are often listed separately. Before buying, check:

  • How long is the illuminated section?
  • How long is the connection cable?
  • Can the strip be cut at the marked points?
  • Do you need a connector for corners?

You can’t fold an LED strip just any way you like, either. Tight bends can damage the circuit tracks and LEDs.

2. Assuming “waterproof” means suitable for every outdoor use

The IP rating describes how well a product is protected against the ingress of solid objects and water. A model rated IP20 is intended for dry indoor spaces only. IP44 offers protection against splashes, but the product isn’t suitable for immersion. The same applies to IP65: rain and splashes are not the same as prolonged immersion.

If you’re using a strip in the garden, on a balcony or on a terrace, check the IP rating of the power supply and control box too. A solar-powered string light needs a different installation from a mains-powered LED strip.

3. Treating RGB, RGBIC and RGBCCT as if they were the same

An RGB LED strip typically produces colours using red, green and blue. Depending on the model, white may be created by mixing these colours. RGBIC LED strips can display different colours in individual sections, making colour gradients and flowing light effects possible. RGBCCT adds adjustable white to RGB, with options ranging from warm to cooler shades of white.

If you mainly want indirect lighting for watching TV or working at your desk, you may not need the most advanced effects controls. But segmented RGBIC effects can be useful for lighting scenes, music synchronisation or gaming.

Key things to consider when buying

Power supply and installation

A mains-powered LED strip needs a suitable socket and enough room for the adaptor or control box. If you’re installing a self-adhesive LED strip, the surface should be smooth, dry and free from dust and grease. Adhesion may be reduced on rough plaster, dusty wood or silicone-coated surfaces.

It’s a good idea to test the strip before installation. This lets you check that the connection cable, controller and socket will all reach the chosen spot. Don’t leave the strip tightly coiled while it’s switched on, as heat can build up.

Controls and smart home compatibility

An LED strip with a remote control is easy to use without setting up an app. Wi-Fi models also let you set schedules, groups and scenes. If you’re considering a Wi-Fi LED strip, check which Wi-Fi band it requires. According to the product information, the Hama model described here is set up using 2.4 GHz Wi-Fi.

A Matter LED strip can be connected to compatible platforms. However, how you control it still depends on the app, smartphone, voice assistant and smart home hub you use. Before buying, check whether Apple Home, Google Home, Alexa, Samsung SmartThings or Home Assistant is actually supported.

Brightness, colour temperature and dimming

“Dimmable” doesn’t automatically mean that every control method offers stepless adjustment. On compatible models, you can adjust the brightness using an app, remote control or voice command. Colour temperature matters if you want functional white light. An RGBCCT model with a range of 2,700 to 6,500 K can produce warmer and cooler shades of white. For purely decorative lighting, colour modes, flowing effects and the number of LEDs per metre are more important.

LED strip FAQs

How do you install an LED strip correctly?

First, measure the area you want to cover and unroll the strip fully. The surface must be dry, smooth and free from dust or grease. You can then gradually peel off the backing from the adhesive. Only cut the strip at the marked points. Keep the power supply and control box uncovered and well ventilated.

How long does an LED strip last?

Its lifespan depends on factors including how long it’s used, heat dissipation, the power supply, installation and surroundings. Don’t leave an LED strip tightly wound while it’s switched on. For outdoor models, you’ll also need to consider moisture, temperature and direct exposure to the elements. Always check the product information for specific lifespan details.

How much does it cost to run?

Running costs depend mainly on power consumption, daily usage and your electricity tariff. A 24 W model used for ten hours would theoretically consume 0.24 kWh per day. For a more accurate estimate, multiply the wattage listed on the power supply or product by the actual running time. Lower dimmer settings and shorter usage times can help reduce consumption.
