LED String Lights and LED Strips: A Buying Guide to Finding the Right Lighting

LED lighting can add a targeted touch to living spaces, cupboards, balconies and gaming set-ups. However, unclear product specifications can easily lead to the wrong purchase. When choosing LED string lights and LED strips, don’t focus solely on colours and promotional images. Consider where you’ll use them, how they’re powered, their IP rating and how they’ll be installed.

Common pitfalls when buying LED lighting

1. An IP rating is mistaken for complete weatherproofing

A rating such as IP44 means protection against solid objects and water splashes from different directions. This may be suitable for a covered patio or sheltered balcony, for example. However, the battery box must not be immersed in water.

IP20, on the other hand, is intended for dry indoor spaces. An LED strip 5 m with an IP20 rating shouldn’t be fitted to an exposed exterior wall or left out in the rain. For outdoor use, consider products such as an outdoor solar string light with a clearly stated higher IP rating. Even then, the solar panel must not be submerged.

2. The lighting functions are overestimated

RGB and RGBIC are not the same:

  • RGB typically combines red, green and blue to create different colours. Depending on the product, white tones or preset effects may also be available.
  • RGBIC can control multiple colour zones along a strip at the same time, creating gradients or running-light effects.
  • A warm white LED string light is better suited to decorative accents and a relaxing ambience.
  • An LED light strip with 6000 K produces cool, bright light and may be suitable for cupboards, work surfaces or dressing areas.

Multicolour LED lighting doesn’t automatically replace functional room lighting. The right choice depends on the length, brightness, installation location and intended use.

3. Installation and power supply are checked too late

A self-adhesive LED strip will only stick reliably to clean, dry and smooth surfaces. Dust, grease, rough walls or frequent exposure to heat can affect how well it adheres. Avoid sharply bending the strip around corners.

Before buying, also check:

  • Is there a power socket nearby?
  • Will a battery-powered LED string light last as long as you need it to?
  • Do you need a USB connection?
  • Is a power adapter included?
  • Is the strip the right length, without needing to be cut or extended in a way the manufacturer doesn’t allow?
  • Does the smart LED lighting need a 2.4 GHz Wi-Fi network, Bluetooth or a compatible smart home hub?

Key technical points at a glance

Length and LED density

An LED strip 5 m is often a good fit behind a television, along shelves or around the edges of a ceiling. LED density affects how evenly the light appears. The 5050 RGB set mentioned here has 150 LEDs over 5 m, or 30 LEDs per metre. By contrast, an LED light strip measuring 60 cm is designed for individual cupboard compartments, wardrobes or work areas.

Measure the area before ordering, and allow for the power adapter, controller and connecting cable. For a long run, the position of the power adapter may affect installation more than the strip’s length.

Power supply and run time

Battery-powered models can be used wherever there’s no power socket. Run time depends on the type of battery, light mode and frequency of use. A timer and memory function can make them easier to use.

A rechargeable model with a USB connection is suitable for everyday indoor use, but needs to be charged regularly. A power adapter keeps the strip supplied with power, but you’ll need an accessible socket. Smart products also require app set-up and a network connection.

IP rating, sensors and controls

A motion-sensor LED cupboard light can be useful in a kitchen, cupboard or hallway. The sensor on the 60 cm model described here detects movement up to around 2 m away and switches the light off automatically after about 30 seconds. The stated battery capacity is 2200 mAh, and the charging time is approximately five hours.

For outdoor areas, the IP rating, the position of the power adapter or solar panel, and local weather conditions are all important. An outdoor solar string light needs direct sunlight to charge its battery sufficiently.

Frequently asked questions about LED string lights and LED strips

How do you attach an LED strip securely?

The surface should be dry, clean, free from grease and as smooth as possible. It’s a good idea to test the adhesive on a small section before installing the whole strip. For longer strips, an additional mounting profile may be useful. Avoid sharply bending the strip at LED chips and connectors.

How long do LED string lights last?

Their lifespan depends on LED quality, heat dissipation, operating time and power supply. A lifespan stated by the manufacturer is a guide, not a guarantee of how long the lights will last in your home. For mains-powered models, don’t use the product while it’s coiled if this could prevent heat from escaping.

How much does it cost to run an LED string light?

Running costs depend on power consumption, daily operating time and your electricity tariff. The simple calculation is: power in watts divided by 1000, multiplied by the operating hours and the price per kilowatt-hour. For battery-powered models, you’ll need to factor in the cost of batteries or recharging the battery instead of electricity costs.
