How to Choose Lights for an Outdoor Party

Most lights for an outdoor party fail because people hang indoor fairy lights outside and the first bit of dew or rain kills them within a week. Weatherproofing is rated by an IP number, and anything below IP44 is not built to handle an Australian backyard overnight, let alone a sprinkler or a sudden storm. Once you sort that out, the real decision is just three things: the style of light, how much power you can get to the space, and how big the area is.

There are three main styles people choose for a yard, deck or garden party: festoon lights, string lights and decorative lights. Festoon lights use larger bulbs spaced further apart and suit bigger areas like a side yard or a driveway set up for a milestone birthday. String lights pack in smaller bulbs closer together and work well for intimate spaces like a balcony or a dessert table at a baby shower. Decorative lights cover shaped pieces, like stars or pet silhouettes, and are better for accents than for lighting a whole space. Picking between them comes down to how many square metres you need to cover, whether you have an outdoor power point nearby or need battery or solar options, and what kind of party you are throwing.

Why Outdoor Lights Need Different Rules Than Indoor

Outdoor conditions put real stress on a light fitting that an indoor space never sees. Rain and dew sit on the casing, wind pulls at the cord and connections, and insects get into any gap in the housing. A fitting built for a lounge room ceiling was never tested against any of that.

Cold nights cause a different failure. Plastic housings made for indoor use get brittle in low temperatures and can crack, and cheap wiring insulation can split, which leads to a short the next time it gets wet. This is why a product like waterproof festoon string lights lists both an indoor and outdoor rating on the same box.

Bulb type also changes what the lights are good for once you're outside.

Festoon String or Decorative Which One Wins

The right style depends on the space you're lighting, not just what looks nice in a photo. Festoon lights use G40 or larger bulbs on a thick rubber-coated cable, built to carry weight and handle wind without sagging, which is why they suit patios, alfresco dining areas and anywhere people will be sitting underneath them for hours. A curtain fairy string light set runs cheaper and lighter, so it works better draped over a fence, wrapped through a tree, or strung along a small balcony rail.

Decorative lights trade coverage for character. Lanterns, globes and shaped pieces are not meant to light a whole yard, they're meant to be the thing guests photograph, so they earn their spot at a themed party or as a focal point near a gift table or cake stand.

Festoon cable can take the weight of large bulbs over a 10 to 20 metre run, something fairy lights are not built for. Here's how the three stack up on the things that actually decide a purchase.

Getting the Power Source and Weather Rating Right

IP44 and IP65 cover the two situations most outdoor parties will face. IP44 handles light rain, splashes and dew, which is fine for a covered patio, while IP65 is rated for direct rain and can be hosed down, which matters if the lights will sit in an open yard overnight with no cover at all.

Power access decides the rest. Mains-powered plug-in lights suit a patio or deck near an existing power point, since you get a steady, strong supply with no batteries to swap out mid-party. Solar lights suit a garden bed, a fence line or a yard with no power run to it, and products like the solar LED deck lights charge through the day and switch on automatically once it's dark.

Before you add anything to cart, run through this list.

• Check the IP rating matches where the lights will actually sit, not just where you plan to hang them first.
• Confirm the plug is a standard Australian three-pin and matches your extension cord rating.
• Count how many power points you'll need if you're linking more than one set.
• Decide if solar makes more sense for any area with no power access at all.

Best Lights for Small Patios and Big Backyards

Space size decides the light type more than any other factor. A small balcony or patio only needs a short string light set or a compact festoon run, since anything longer will bunch up or trail on the ground with nowhere to hang. Medium courtyards do best with festoon lights hung between two fixed points, like a wall bracket and a tree, which keeps the cable taut without sagging in the middle.

Large backyards or marquee setups need longer festoon runs, or several string light sets linked together to cover the full perimeter. Measure the space before you buy, since running short on length halfway through hanging is the most common reason people end up with a gap over the dinner table.

• Small balcony or patio: a short string set or compact festoon kit under 10 metres.
• Medium courtyard: one festoon run strung between two solid anchor points.
• Large yard or marquee: multiple linked string sets, such as an 800 LED curtain fairy light set, or a long festoon run across the whole span.
• Any space with garden beds or path edges: solar stake lights lining the route guests will walk.

Matching Light Colour and Style to Your Party Theme

Colour sets the mood faster than any decoration on the table. Warm white suits weddings, engagement parties and sit-down dinners, since it reads as soft and classic in photos and doesn't clash with floral arrangements or table settings. Multicolour or colour-changing sets suit kids' birthdays and Halloween, where the brief is fun and bold rather than refined.

Shaped decorative lights, like stars, globes or lanterns, suit themed parties and work well as a backdrop for photos, since guests will naturally gather near the brightest or most unusual feature in the yard. Pair the lights with matching tableware and decorations rather than treating them as a separate purchase, since a warm white festoon run over a mismatched bright plastic table setting undercuts the whole look.

• Warm white: weddings, engagement parties, dinner gatherings.
• Multicolour or colour-changing: kids' birthdays, Halloween, pet birthday parties.
• Shaped decorative, such as a hanging Moroccan lantern: themed parties, photo backdrops, garden focal points.

Weatherproofing or Style Which Should Win

Weatherproofing wins every time, because a light that stops working on the night costs you more than a plain white bulb ever would. A set rated IP44 or higher will survive dew and a light shower, while a pretty indoor-style string will not make it to dessert if the grass is damp. Pick the rating first, then choose the look from whatever meets that standard.

Buying a run that's slightly too long beats buying one that's exactly the right length on paper. Measurements are never perfect once you're actually hanging lights around a tree, a fence post or an awning, and a few spare metres lets you adjust without leaving a dark gap over the food table. A set like the 500 LED curtain fairy string lights gives you that extra room to work with on a mid-size patio or courtyard.

Here's how the three buying priorities compare once you're actually choosing between sets.

Shopping pre-tested outdoor sets removes most of this guesswork, since the rating and the length are already confirmed before the box arrives.

Measure Up and Order Before the Date

Walk your yard, deck or patio with a tape measure and write down the actual distance you need to cover, plus how many power points sit within reach of that space. That one number tells you whether you need a short balcony run or a longer festoon kit, and whether solar is your only real option in a spot with no outdoor socket. Order at least two weeks ahead of the party, since most delays come from waiting on a reorder after the first set turns out too short. Let's Party ships free across Australia, so getting a backup length sent out doesn't add a courier cost on top of the wait. Once the lights are on the way, the only job left is hanging them and watching the yard light up once the sun goes down.

Outdoor Party Light Questions Answered

Can I connect multiple festoon light sets together to cover a bigger area?

Most festoon sets can be joined end to end, but check the box for a maximum connected length or wattage limit before you link more than two or three runs. Going past that limit on one power point can trip a circuit or overheat the cable. If you need serious coverage for a marquee or full backyard perimeter, linking several shorter sets is still safer than one long custom run.

Will outdoor lights still work if my patio isn't covered by a roof?

Yes, as long as the lights carry an IP65 rating, which is built for direct rain and open exposure overnight. An open patio with no roof gets hit by dew, wind-blown rain and full sun through the day, so anything rated lower than IP65 is a gamble in that spot. The rating matters far more here than whether the fitting looks sturdy.

Do I need an electrician to install outdoor party lights safely?

No, plug-in festoon and string lights designed for home use don't need an electrician, since they run off a standard three-pin outlet like any other appliance. You only need a licensed electrician if you're adding a new outdoor power point, running cable through a wall, or wiring lights into your home's fixed circuits rather than plugging them in.

What happens if my outdoor lights get rained on before I've set them up?

A sealed, correctly rated set handles this fine, since the weatherproofing covers storage and transit exposure the same way it covers overnight use. Dry the plug and connector points with a cloth before you switch anything on, just to be safe. Let's Party tests its outdoor sets for this kind of exposure, so a soaking before installation isn't a reason to return them.
