You want to add a little magic to your patio or bedroom, and fairy lights are one of the easiest ways to do it. A casual weekend braai or a full wedding setup both change completely once you add the right string of tiny warm lights.
Picking the right ones takes a bit more thought than grabbing the first box you see though. Power source, cable colour, length, and weatherproofing all matter more than people expect. This guide walks you through what to look for, so you end up with lights that actually suit your space.
Let's start with how you'll power them.
How to choose the right power source
Your power source decides where and how you can actually use your lights.
Plug-in fairy lights are the most reliable option if you're setting up somewhere permanent. No fading power, no cloudy days to worry about, just consistent brightness every evening. They're a great fit for patios, entertainment areas, and anywhere close to a plug point.
Solar fairy lights are a brilliant option for anywhere further from an outlet, garden beds, fences, balcony railings, or trees you want to wrap without running a cable across the lawn. Set the panel somewhere sunny, and the lights switch on automatically once it gets dark. They're a popular choice for South African gardens specifically, since they keep glowing through load shedding without costing a cent to run.
Battery operated fairy lights give you total freedom indoors. Our curtain fairy lights fall into this category, ideal for a bedroom wall, a window, or anywhere you want that soft, layered glow without a nearby plug point or an unsightly cable running across the room.
USB powered fairy lights are a great fit for a home office, a desk setup, or a teenager's bedroom. Plug straight into a laptop, a power bank, or a standard USB wall adapter, no bulky plug socket needed, just steady, reliable power.
Once you know your power source, the next question is what the cable itself should look like.
Cable colour matters more than you'd think
The cable colour changes both how the lights look switched off during the day and how well they blend into their surroundings.
A dark green cable disappears into foliage, hedges, and garden structures almost completely, so during the day you barely notice it's there. It's a great choice for wrapping trees, pergolas, and anywhere greenery is doing most of the visual work. A black or clear cable tends to suit indoor use better, bedroom canopies, shelves, and tablescapes, where you want the lights themselves to be the focus rather than blending in.
Worth thinking about before you buy, since it's an easy detail to overlook until the lights are already up.
Understanding lengths and bulb counts for your project
Buying a set that's too short is frustrating. Buying one that's too long leaves you with an awkward bundle of extra wire you don't know what to do with.
For a smaller space, something like a 20m set with 200 warm white LEDs gives you an even, gentle glow across a modest garden bed, balcony, or a single tree. For a bigger job, a 30m set with 300 warm white LEDs covers more ground, and if that's still not enough, connectable sets let you link multiple strings together, some go all the way up to 60m of combined coverage.
If you're covering a genuinely large space, a venue, a big garden, a full wedding setup, our Ultimate Collection includes connectable fairy lights rated IP66 for full outdoor exposure, connectable up to 200m. That's built for scale, not just a home garden.
Our best tip before you buy anything: measure your space with a piece of string first. Drape it exactly how you want the lights to hang, leave a little slack, then measure that. It saves you from buying the wrong length twice.
Why waterproof ratings matter for outdoor use
South African weather can turn quickly. A sunny afternoon braai can end in a proper downpour, so if your lights are going outside, the IP rating actually matters.
Here's a quick breakdown:
- IP44 is splash resistant, handling light rain and general outdoor conditions, ideal for covered patios and pergolas
- IP65 is fully dust tight and protected against water jets from any direction, suitable for open outdoor use including direct rain exposure
- IP66 is fully dust tight and protected against powerful water jets, like our Clear Heavy Duty Fairy Lights in our Ultimate Collection carries this rating for permanent, fully exposed installations
As a general rule, if your lights are under some kind of cover, IP44 is plenty. If they're going to sit fully exposed to the weather year round, look at IP65 or higher.
Extra features worth knowing about
Modern fairy lights do a lot more than just switch on and off.
Multiple lighting modes, steady glow, slow fade, gentle twinkle, give you options depending on the mood you're going for. A slow fade suits a quiet evening, while a twinkle setting adds a bit of energy to a party or event.
Note that our plug in dimmers and timers are designed for our string and festoon lighting range, they aren't compatible with our fairy lights, so if you want mode control on fairy lights specifically, the Ultimate Collection's built in button is the way to get it.
And if you're deciding between colours, warm white gives that cosy, golden glow that suits almost any outdoor gathering, neutral white is crisper and more modern, and multicolour is the natural choice for a festive or event setting.

Frequently asked questions
How long do LED fairy lights last?
LED technology is incredibly efficient. The LED bulbs in our products are designed to last up to 30,000 hours. If you run them for five hours every single night, the bulbs could technically last for over twenty years. The wiring or the power source will usually wear out long before the actual LED bulbs fail.
Can I leave them outside all year?
Yes, as long as they carry the right IP rating for how exposed they are. IP44 suits a covered patio, IP65 or IP66 suits anywhere fully open to the weather.
Are they safe to use in bedrooms?
Absolutely. LED bulbs generate very little heat, making them completely safe to drape over fabric, curtains, or bed frames. They will not burn your hands or create a fire hazard like old-fashioned incandescent bulbs used to.
What's the difference between plug-in and solar fairy lights?
Plug-in gives you consistent, reliable brightness every night regardless of weather. Solar charges during the day and switches on automatically at dusk, no plug point needed, and it keeps working through load shedding.
How long do connectable sets go before I need another power source?
Our standard connectable set links up to 60m. For anything larger, our Ultimate Collection connectable fairy lights go up to 200m from a single setup.
What happens if one bulb breaks?
In modern parallel-wired LED strings, if one bulb breaks or burns out, the rest of the string will stay lit. You do not have to worry about the entire string going dark just because of one faulty tiny bulb.
Adding a warm glow to your home does not have to be complicated. By choosing the right power source, measuring your space carefully, and picking a durable wire, you can create a beautiful atmosphere that lasts for years. Take a look at your space, decide what kind of mood you want to set, and start bringing a little bit of magic into your everyday life.
