Outdoor Festoon Lights: How to Choose the Right Type for Your Garden (UK)
Table of Contents
Outdoor festoon lights are decorative bulb string lights designed for gardens, patios and pergolas, combining practical illumination with a warm ambient glow. Most modern options use LED technology and are available in mains-powered, solar and connectable formats suited to UK outdoor conditions.
If you’re choosing outdoor festoon lights for your garden, the right setup depends on layout, power source, brightness expectations and whether you plan to extend the run in future. This guide explains what matters so you can choose confidently and avoid common mistakes.
Choosing Outdoor Festoon Lights
- Choose mains-powered for consistent brightness and regular use.
- Choose solar where sockets are impractical and usage is occasional.
- Use LED festoon lights for lower running costs.
- Select connectable systems for larger gardens or longer spans.
- Plan fixing points before buying to avoid sagging or uneven runs.
What Are Outdoor Festoon Lights?
Outdoor festoon lights are evenly spaced bulb string lights designed for external use. Unlike fairy lights, the bulbs are larger and more defined, creating structured illumination rather than scattered sparkle. They are commonly installed along fences, across pergolas, above patios or in overhead canopy layouts to define social spaces after dark.

Are Outdoor Festoon Lights Bright Enough?
Brightness depends on placement, spacing and power type. Mains-powered LED festoon lights typically provide more consistent usable light for dining and entertaining. Solar festoon lights tend to produce a softer glow, making them better suited to ambient perimeter lighting rather than task-style illumination.
If you plan to dine under the lights regularly, positioning them directly above the table at a moderate height will produce better coverage than mounting them only around the garden edges.
Mains vs Solar Festoon Lights in UK Conditions
Mains-Powered Festoon Lights
Mains systems offer consistent brightness regardless of daylight hours. They are typically the better option for permanent installations or larger gardens where reliability matters. Performance does not fluctuate seasonally, making them ideal for year-round setups.
Solar Festoon Lights
Solar festoon lights are practical where outdoor sockets are limited. They work best when the solar panel receives strong daylight exposure. In winter, shorter days can reduce runtime, so expectations should align with seasonal performance.
If you are considering a solar option, this example shows a typical format and run length: solar festoon lights.

Are Festoon Lights Waterproof and Safe Outside?
Outdoor-rated festoon lights are designed to handle rain and changing weather when installed correctly. Look for weather-resistant cabling and appropriate outdoor suitability. Avoid placing connectors where water can pool, and ensure cables are supported to prevent strain.
For permanent installations, positioning plug connections in sheltered outdoor sockets or weather-protected enclosures helps maintain long-term performance.
Connectable Festoon Lights for Larger Gardens
Connectable festoon systems allow you to extend the lighting run without relying on multiple independent plug points. This produces a cleaner visual result and simplifies garden layout planning.
- Ideal for long fence lines
- Useful for pergola plus patio combinations
- Effective for symmetrical canopy layouts

Do LED Festoon Lights Use Much Electricity?
LED festoon lights are generally energy efficient compared to traditional filament bulbs. Power usage depends on wattage and number of bulbs, but LED systems are designed to deliver steady brightness with lower electricity consumption. For frequent evening use, LED is typically the practical choice.
Where Should You Hang Outdoor Festoon Lights?
Pergolas
Wrap beams or create a simple canopy across the structure. Support the cable at regular intervals to prevent sagging.
Fence Lines
Maintain consistent height and spacing for a structured perimeter effect that defines the garden after dark.
Overhead Canopies
Anchor to strong fixing points and plan gentle curves rather than deep droops. Even spacing improves overall appearance.

How Do You Choose the Right Festoon Lights for a Garden?
Choose outdoor festoon lights based on garden size, power access and intended brightness. Mains-powered LED systems suit permanent dining and seating areas. Solar options work for smaller spaces with good daylight exposure. Connectable systems are best for longer runs or expandable layouts.
FAQs About Outdoor Festoon Lights
Can festoon lights stay outside all year?
Outdoor-rated festoon lights can remain outside year-round if installed correctly and supported properly. Protect connectors from standing water and avoid placing strain on cables to extend lifespan.
Are festoon lights suitable for winter use?
Mains-powered festoon lights generally perform consistently in winter. Solar performance may reduce due to shorter daylight hours and lower sun angles.
How high should festoon lights be hung?
For canopy setups, hanging lights slightly above head height provides ambience without glare. Fence and pergola installations should maintain even spacing and secure fixing points.
What is the difference between fairy lights and festoon lights?
Fairy lights use small closely spaced LEDs for sparkle effects. Festoon lights use larger evenly spaced bulbs, creating more defined and structured illumination suitable for larger outdoor spaces.
