LED string lights can add decorative lighting to your living room, balcony, patio, garden or event space. But when buying, there’s more to consider than the number of LEDs and the colour of the light. Unclear weather-resistance claims, an unsuitable power supply or exaggerated runtime promises can all lead to disappointing purchases.
Waterproof string lights aren’t automatically suitable for immersion in water. IP44 typically protects against splashes, while IP65 indicates a higher level of protection against dust and water jets. However, battery compartments and solar panels may be more vulnerable than the lights themselves.
So, when choosing outdoor string lights, check:
Two models measuring five metres can look very different. The key factors are the number of LEDs, the spacing between them and the shape of the lights. A string with lots of small LEDs creates a more even effect. Larger G40 bulbs, on the other hand, add individual points of light and work well on pergolas, railings and event spaces.
Also check whether the power lead is included in the total length. A compact set of indoor string lights may be enough for a balcony or smaller room, while garden paths and patios may need several strings connected together.
Solar string lights need enough direct sunlight. Shade, short days and dirty solar panels can all affect how well they charge. Claims of 8 to 14 hours of lighting should therefore be treated as estimates that depend on the product and the weather.
For indoor spaces, covered balconies or events without reliable sunlight, battery-operated string lights may be more practical. Check whether batteries are included and how easy it is to access the battery compartment.
Warm white string lights create a subtle look and are often a good fit for living rooms, patios and weddings. Cool white at around 6500 K looks more like daylight and can be used to create crisp decorative accents. Multicoloured string lights are better suited to parties, children’s bedrooms and seasonal decorations.
Multiple modes, dimming, a memory function and a timer give you more ways to customise the lighting. A timer can reduce the need for daily adjustments, but it doesn’t replace switching the lights off when you’re away for an extended period.
Measure the area before you buy, allowing extra length for curves, fixing points and the power lead. IP ratings are particularly important outdoors. A model rated IP20 is designed for dry indoor spaces only and shouldn’t be used on a balcony, patio or in the garden.
Why this product suits this profile: With 50 LEDs and battery power, these lights can be used in living rooms, on sheltered balconies or at small gatherings without needing a socket. Warm white light and eight modes give you plenty of ways to decorate.
The product details specify that the lights run on three AA batteries, and include a timer and an IP44 rating. This makes it easier to understand where they can be used, but the battery compartment must still not be immersed in water.
5 m length, 50 LEDs, eight lighting modes, memory function and timer, according to the product details.
Why this product suits this profile: Two flexible copper-wire strings, each with 120 LEDs, provide wider coverage for gardens, patios, balconies and festive decorations.
The product details state that the string lights are rated IP65 and that the solar panel needs to be positioned in an unshaded spot. This helps you plan your outdoor installation more accurately.
Solar-powered, automatic on/off function, eight modes and memory function, according to the product description.
Why this product suits this profile: With 23 G40 bulbs, these lights are a good choice if you want to decorate longer stretches of patio, pergola, garden or event space.
The product description lists a length of 20 m, replaceable bulbs, dimming and the option to connect multiple strings. Check compatibility with any dimmers you already own before buying.
23 G40 LED bulbs, IP65 rating, timer, dimming and the option to connect up to 500 bulbs in total, according to the product details.
Why this product suits this profile: This RGB LED strip is designed for dry indoor spaces such as living rooms, bedrooms, kitchens and home bars, where it provides colourful accent lighting.
The IP20 rating is specified for indoor use only, making it clear that this product isn’t suitable as outdoor string lighting.
5 m length, 150 RGB LEDs, IR remote control, adjustable brightness and 24 V power supply, according to the product description.
We’ve put together a complete, regularly updated list of products that meet these strict selection criteria and the safety regulations in force in the EU.
Use suitable cable clips, hooks or cable ties, and avoid sharp bends. Protect the power supply, battery compartment or solar panel from prolonged exposure to moisture. For solar string lights, it’s essential to position the panel in a sunny spot without shade.
Lifespan depends on the LED components, how long the lights are used, exposure to moisture, mechanical stress and the power supply. For example, a stated lifespan of 15,000 hours should be understood as the manufacturer’s technical estimate, not a guarantee of how long the lights will last in all conditions. Switch them off when they won’t be used for an extended period, and store them somewhere dry.
Running costs depend on power consumption and how many hours the lights are used each day. For mains-powered models, power consumption is usually listed in watts on the product data sheet. Battery-powered models also incur the cost of replacement batteries, while solar-powered versions work without an external power supply when they receive enough sunlight.
