Multicolour LED string lights can add decorative lighting to a balcony, garden, living space or celebration. However, many products look similar at first glance. Differences often only become clear when you install them, connect the power supply or use them outdoors.
Three common buying pitfalls are worth keeping in mind:
If you’re looking for outdoor LED string lights, the IP rating is an important point of comparison. The first digit describes protection against solid objects, and the second describes protection against water.
When choosing waterproof string lights, also check whether the protection rating applies to the entire light, just the LED wire or only certain components. Solar panels, battery compartments, power adapters and plugs may have different requirements.
A 12-metre string light with 120 LEDs distributes light differently from a 4-metre model with 50 LEDs. A shorter option is often enough for railings, small balconies or table decorations. Trees, hedges and longer façades need more reach.
Check the:
Copper wire string lights can usually be wrapped flexibly around branches, railings or decorations. However, avoid sharply bending the thin wire or leaving it under constant tension.
Solar-powered lights are suitable for places without a power socket. How long they stay lit depends on sunlight, the time of year, the panel’s position and the weather. The VIVREAL models mentioned here are specified as needing 6 to 8 hours of charging time, with a lighting duration of 8 to 14 hours depending on the weather.
Battery-powered models don’t depend on sunlight and can be positioned flexibly for camping, parties or indoor use. Check whether batteries are included. For example, the M.TK model requires 3 AA batteries, which aren’t included.
An LED strip light 5 m with a 24-volt power adapter is designed for indoor use. The RGB model mentioned here has an IP20 rating, so it shouldn’t be used in the rain, on an unprotected balcony or in damp areas. A remote control, dimming function and choice of colours offer flexible options for living rooms, bedrooms, shelves or party decorations.
Why this product suits this profile: This battery-powered model is ideal for short decorative runs, balconies, camping, parties and rooms without a power socket. Remember to buy the 3 AA batteries separately.
The total length of 4.3 metres and the 50 LEDs are clearly stated. The IP44 rating indicates protection against splashes, not suitability for use underwater.
50 LEDs, 8 functions with memory mode and flexible battery placement.
Why this product suits this profile: Two long solar string lights, each 12 metres long with 120 LEDs, are ideal for larger gardens, patios, trees or festive outdoor spaces.
The IP65 rating and solar charging time are specified. The panel needs direct sunlight; neither the panel nor the LEDs should be submerged.
8 lighting modes with memory function, copper wire and automatic on/off.
Why this product suits this profile: This 5-metre RGB strip light is designed for indoor spaces such as living rooms, kitchens and bedrooms, or for the area behind a television.
The IP20 rating makes it clear that this product is for indoor use. This helps prevent it being used outdoors without protection.
150 LEDs, RGB colour selection, dimming function, infrared remote control and 24-volt power adapter.
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.
Before buying, plan how you’ll attach the lights and where you’ll place the power source. The solar panel should face south, or another sunny direction, with as little shade as possible. Clean it occasionally with a soft, dry cloth.
For Christmas lights and decorative string lights, don’t trap cables under doors, carpets or heavy objects. Keep battery compartments closed. If you have children at home, make sure cables are routed safely, as thin wires can pose a tangle risk.
Their actual lifespan depends on the LED components, rechargeable or standard batteries, weather conditions, storage and physical wear. For outdoor models, storing them somewhere dry over winter and regularly checking the cables and casings can help extend their useful life. It’s not possible to give a reliable lifespan without specific information from the manufacturer.
Consumption depends on the number of LEDs, power rating, how long the lights are on and the model. Solar and battery-powered models don’t draw power directly from your home’s mains supply. The 5-metre LED strip light mentioned here is rated at around 12 to 18 watts. To calculate running costs, multiply the power in kilowatts by the number of hours used each day and your electricity tariff.
That depends on the design and the manufacturer’s instructions. Cold weather, shorter days, snow and less direct sunlight can reduce charging performance. Don’t let the solar panel become covered by water or snow. If you won’t be using the lights for a long time, it’s a good idea to switch them off and store them somewhere dry, following the manufacturer’s instructions.
