LED string lights for indoor and outdoor use: how to choose for balconies, gardens and celebrations

LED string lights for indoor and outdoor use can add decorative lighting to windows, balconies, patios, gardens and retail spaces. In practice, however, poor purchases are often down to unclear product information or choosing lights that aren’t suitable for where you plan to use them, rather than any issue with the LED technology itself.

Common pitfalls when buying LED string lights

1. Mistaking IP44 for complete weather protection

The IP44 rating means protection against solid objects larger than 1 mm and water splashes from various directions. This makes it suitable for sheltered outdoor areas such as a covered balcony, patio or partially protected area of the garden. However, it does not automatically protect against heavy rain, snow or standing water.

Important: the power supply, plug and controller may have a different protection rating. Keep them dry, and don’t place them in a puddle or leave them unprotected on the ground.

2. Length alone doesn’t tell you how the lights will look

A 50-metre string of lights can look very different depending on the number of LEDs. So always check:

  • Total length and lead cable length
  • Number of LEDs and spacing between them
  • Light colour, such as warm white or multicoloured
  • Cable type, such as copper wire, PVC cable or a net
  • Whether you can connect multiple sets

A string of lights for the garden or balcony could be a good choice for a hedge. For a window, LED curtain lights or an LED light curtain usually create a more defined look. LED net lights are handy for bushes and fences, as they cover an area more evenly.

3. Solar and mains-powered options aren’t always clearly distinguished

A solar string of lights needs enough daylight to charge its battery. In winter, under a balcony or in a shady spot, the lights may not stay on as long. Mains-powered options need a plug socket, but their light output isn’t dependent on sunshine.

Also check that the product version is genuinely solar-powered, rather than a similarly named model that comes with a power supply. Check the details for the specific version you’re buying, including the timer, USB cable, adapter and remote control.

The key technical features to consider

Light colour and where you’ll use it

Warm white light is well suited to living rooms, bedrooms, windows, weddings and subtle Christmas decorations. Multicoloured LEDs are better suited to parties, Halloween, Easter or bolder displays. For everyday use, a decorative string of lights with a steady-light mode is often more convenient than one that starts a flashing programme every time you switch it on.

Lighting modes, memory function and timer

A string of lights with 8 modes typically offers combination, waves, sequential lighting, slow fade, flashing, twinkling and steady light. The number of modes isn’t the only thing that matters: ease of use is important too.

A memory function brings back the last mode you selected when you switch the lights on again. A timer can limit the operating time to, for example, 3, 5 or 8 hours. Some products are operated using a button on the adapter, while others also come with a remote control. A remote can be handy for windows or other hard-to-reach spots.

Power supply and installation

Low-voltage systems may use a transformer. Product information should clearly state the input voltage, output voltage and power consumption. Lay cables without pinching them, and secure the lights so they don’t create a trip hazard or pull on the cable.

If you’re choosing string lights for a wedding or party, installation time is another consideration. Flexible copper wire can be shaped around railings, plants or furniture. Net lights, on the other hand, can be draped over larger areas such as bushes, fences or walls.

Frequently asked questions about LED string lights for indoor and outdoor use

Can IP44 string lights stay outside all the time?

IP44 string lights are designed for protection against water splashes and use in sheltered outdoor areas. In heavy rain, snow or frosty conditions, or if you won’t be using them for a while, take them down or store them somewhere protected. The controller and power supply must be kept dry.

How much electricity do LED string lights use?

Consumption depends on the number of LEDs, power rating and how long the lights are on. If the stated power is 3.6 W, running them for six hours uses around 0.0216 kWh per day. To work out your own costs, multiply the power in kilowatts by the hours of use and your electricity price.

How do you hang string lights without causing damage?

Use suitable cable clips, hooks or cable ties, and avoid sharp edges. The cable shouldn’t be under tension. Unplug the lights before moving or cleaning them. When installing them outdoors, protect the connections from direct contact with water and don’t leave them on the ground.
