Searches for outdoor lighting have shot up 90% as the weather warms up, which means one thing. The nation has collectively looked out of the window, seen a drab and uninspiring patch of decking, and decided enough is enough.
The trouble is… more lights doesn't automatically mean a better garden. That’s right, we said it. But hear us out. String too many fairy lights around a tree willy-nilly and you'll end up with something that looks less "al fresco dining" and more "runway strip."
We sat down with Julia Barnes, our Product Director Guru and certified lighting obsessive, to talk through the garden lighting mistakes she sees time and again, and exactly how to fix them.
Mistake 1: Ignoring colour temperature
This is the big one. Colour temperature is measured in Kelvins (K), and it's the difference between a garden that glows and one that feels like you're being interrogated.
"When lighting up outdoor spaces, anything above 4000K starts to feel clinical," says Julia. "You want warm white, ideally around 2700K, which mimics candlelight and flatters everything from your patio furniture to your slapdash homemade sangria. Cool white belongs in a garage, not a garden party."
The fix is simple. Check the Kelvin rating before you buy and keep it consistent across every fixture. Mixing warm and cool bulbs in the same space is the outdoor lighting equivalent of odd socks. Technically fine, but everyone will notice. And silently judge.
Our outdoor battery lights come with warm white options aplenty, so you can dot them around flowerbeds, plant pots and pathways with zero mismatching mayhem.
Mistake 2: No blend between indoor and outdoor
Your garden shouldn't feel like a different house. If your living room is all warm, layered lighting and your patio is one harsh spotlight, the transition from indoors to outdoors is going to feel jarring rather than seamless.
"Think of your garden as another room," Julia explains. "The same rules apply, so warm tones, thoughtful placement, and fixtures that suit your style. Whether that's sleek and modern or rustic and cosy. Outdoor wall lights either side of your back door are a brilliant way to bridge the gap, they frame the entrance and echo the lighting you've already got inside."
Choosing finishes that complement your interior, rather than clashing with it, makes the whole space feel intentional instead of accidental.
Mistake 3: Relying on fairy and string lights
Fairy lights are the golden retrievers of garden lighting, universally loved but not built to do every job on their own.
"String and festoon lights are fantastic for atmosphere," says Julia, "but they're ambient lighting, not functional lighting. If they're your only light source, you'll end up with a pretty glow and absolutely no visibility for actually finding your drink."
The fix is to treat outdoor string lights and festoon lights outdoor as one layer of a bigger picture, not the whole picture. The icing on the cake. Solar string lights outdoor are brilliant for adding a soft, low-effort sparkle to fences, pergolas and trees, but pair them with something more practical if you're planning to use the space after dark. Our string and festoon lighting range has options for both the fairy lights ideas bit and the functional bit, so you don't have to choose.
Mistake 4: Skipping the layering rule
If there's one tip Julia comes back to again and again, it's this one.
"Good garden lighting works in three layers. Task, accent, and ambient. Task lighting is practical, think steps, seating areas, anywhere you need to see clearly. Accent lighting highlights features like plants, trees or water features. Ambient lighting is your overall mood, your festoon lights, your lanterns, your general glow. Most gardens only have one of these layers, usually ambient, which is why they still feel a bit flat once the sun goes down."
Building in all three doesn't need to be complicated or expensive. Solar lights are an easy way to add accent lighting along borders and pathways without any wiring, while battery operated outdoor lights give you the flexibility to add task lighting exactly where you need it, no matter how far you are from a socket.
Get your garden lighting right
Fixing these four garden lighting mistakes is the difference between a garden you glance at through the window and one you actually want to spend your evenings in. Warm colour temperature, indoor-outdoor cohesion, string lights used properly, and a bit of layering will take you most of the way there.

Your garden lighting questions, answered
What are common garden lighting mistakes?
The most common mistakes are using the wrong colour temperature (too cool and clinical), no cohesion between indoor and outdoor lighting, relying on fairy lights as the only light source, and missing the layering rule of task, accent and ambient lighting.
What colour temperature is best for outdoor lighting?
Warm white, around 2700K, is best for most gardens. It mimics candlelight, flatters planting and furniture, and feels far more inviting than cool white, which can look harsh outdoors.
How do you layer garden lighting?
Layer garden lighting using three types - task lighting for practical areas like steps and seating, accent lighting to highlight features such as trees or water features, and ambient lighting for overall mood, like festoon or fairy lights.
Where should you not put garden lights?
Avoid placing lights where they'll shine directly into windows or seating areas, as this creates glare rather than ambience. Also steer clear of overly damp, unsheltered spots for anything not rated for full outdoor exposure, and don't cluster all your lighting in one layer or one area, spread task, accent and ambient lighting around the whole space.
