Festoon lights are incredibly popular – you’ll see them in gardens, on patios, at weddings, and during events. They instantly add atmosphere and are relatively easy to install – provided you follow a few smart tips. In this guide, we’ll walk you through how to hang festoon lights, what to watch out for, and how to achieve the best results.

Tools & materials you might need

Gather your materials before you start. Depending on your setup, you may not need them all, but it’s handy to have them ready.

- Measuring tape
- Pencil or marker
- Screw hooks or eye bolts
- Wall plugs (for masonry)
- Cable ties or light clips
- Rope or straps (for trees or temporary structures)
- Optional: Steel cable for long spans
- Screwdriver and drill

Step-by-step installation guide

1. Choose the right location

Decide where the lights will add the most atmosphere – above a seating area, along a pergola, or in a tree. Make sure there’s a nearby socket or plan a safe extension cable.

2. Plan the shape and route

Do you want the cable tight, hanging in soft curves, or zigzagging between posts? Measure carefully and add extra length for bends or loops.

3. Select the right type of festoon cable

- Length: Available from 5 to 50 metres
- Connection: With plug or connectable system
- IP rating: Choose at least IP44 for outdoor use
- Lampholders: Choose spacing and bulb type (clear, warm white, coloured, dimmable)

4. Choose your mounting method

- Wooden beams/posts: Use screw eyes or hooks
- Walls: Fit plugs with eye bolts
- Trees or temporary structures: Use rope or straps (non-damaging)
- Long spans: Support with steel cable

5. Hang the cable

Start at the power source and work outwards. Use cable ties (temporary), cable clamps (permanent), or clips (neat finish). Ensure lamp holders hang down and avoid sharp bends or kinks.

6. Install bulbs last

Only screw in the bulbs once the cable is fully installed to avoid breakage. Screw them in firmly but not overtight.

7. Test & enjoy

Plug in the cable and check all bulbs. If dimmable, test different brightness levels. Consider a timer or smart plug for automatic on/off.

Extra tips for a perfect result

- Hanging height: Keep at least 2.2 m above walkways
- Light temperature: Warm white for a cosy, inviting feel
- Secure against wind: Add extra ties or secure along a beam
