Garden Lighting Ideas: How to Light Your Garden for Evening Use
The Importance of Garden Lighting: How to Design Your Garden for Evening Use
Think about when you are actually at home. For most of my clients it's early mornings, evenings and weekends, and for a good half of the year those evenings are dark by the time the washing-up is done. A garden that only works in daylight is one you barely get to see from October to March, and one you have to leave just as a summer evening is getting good.
Many of the people I work with have just finished a renovation: a new kitchen extension with a wall of glass doors looking straight onto the garden. By day it's glorious. Then the sun goes down and those beautiful doors turn into a huge black mirror, reflecting the kitchen back at you. "We spent all that money on the view and at night there isn't one" is something I hear a lot.
The other version is a single fierce security floodlight that makes the patio feel like a car park. Good lighting solves both, and the garden lighting ideas below are among the most transformative things you can add to a garden for the money.
Garden lighting at a glance
Good garden lighting comes down to six things:
Decide what you want to do in the garden after dark.
Light a few chosen features, not the whole space.
Use warm white light, aimed downwards wherever you can.
Hide the fittings, so you see the glow and not the bulb.
Layer practical, feature and atmospheric lighting on separate switches.
Plan the cabling before any paving goes down.
Why does garden lighting matter?
It gives you more hours in your garden. Light a seating area and a path to it, and the garden becomes somewhere to eat, read or have a drink long after sunset.
It gives your glass doors a view at night. This is the benefit people don't expect, and it matters most if you have bifolds, sliding doors or a glazed extension. Glass with darkness behind it acts as a mirror. Light one tree or a fence covered in climbing plants at the far end of the garden and the reflection gives way to a living picture, so the garden stays part of the room all winter, whether or not you step outside. Dimming the indoor lights a little helps too.
It makes the garden safer. Steps, level changes, pond edges and the route to the bins or the back gate all need gentle, reliable light.
It makes a small garden feel larger. Lighting the furthest boundary draws the eye right through the space, so the garden reads as an extension of the room you're sitting in.
What are the main types of garden lighting?
I think about lighting in three layers, much as you would indoors.
Practical lighting covers the things you need to see: steps, paths, doors, the barbecue or outdoor kitchen. Low-level fittings recessed into walls or step risers wash light across the ground without shining in your eyes.
Feature lighting picks out what is worth looking at. The main techniques are:
Uplighting: a spike light at the base of a multi-stem tree or sculptural plant, shining up through the branches. Wonderful in winter on bare stems, but it sends light up into the canopy where birds roost and bats feed, and on into the night sky. Ideally use these sparingly with low output, and on a timer.
Downlighting or moonlighting: a fitting placed high in a tree or on a pergola, shining down through leaves to cast soft, dappled shadows. This is a lovely way to light a tree, as the light lands on the ground where you need it and not in the sky.
Grazing: a light set close to a brick wall, slatted fence or stone surface to bring out its texture.
Silhouetting: lighting the wall behind a plant so its outline stands out in shadow.
Atmospheric lighting is the soft, human layer: festoons over a dining table, lanterns, candles, a fire bowl. It's the least technical layer and often the one that makes people want to stay out.
How do I plan lighting for evening use?
Start with how you'll use the garden. Dining outside, a quiet glass of wine, children playing out after tea and simply enjoying the view from indoors all need different light. Think carefully about this first, because it shapes everything else.
Stand indoors at night. Look out from the places you actually sit and note what you'd like to see. Lighting designed from the sofa and the kitchen sink is lighting you'll enjoy every day.
Choose a few focal points. One good tree, a wall, a water bowl, a seating area. Three or four well-lit features with darkness between them have far more depth and drama than a garden lit evenly from end to end. Shadow is part of the design.
Hide the source. You should see the effect, not the fitting. Tuck lights behind planting, under bench seats and copings, or recess them, and angle them away from where people sit.
Keep it warm. Use amber light <2200K or warm white light, around 2700K, which is flattering to plants, brick and people. Cool white tends to look harsh and clinical outdoors.
Put it on separate circuits. Having the practical lighting, feature lighting and dining area on their own switches or dimmers means you can have the steps lit on a Tuesday in November and the whole garden glowing for a party in July.
Light the structures. In a garden design with pergola or built-in seating, the structure itself can carry the lighting: small downlights in the beams, an LED strip beneath a bench or a floating step. It gives a soft, even glow with nothing on show.
When should lighting be planned?
At the very beginning, alongside the layout and the planting. This is the single most useful piece of advice in this post. Cables and ducting potentially need to run under paving, through walls and beneath borders, so retrofitting lighting to a finished garden means lifting slabs or settling for visible cable and compromises.
Including lighting in the garden design and planning stage costs very little extra on paper. Even if the budget won't stretch to fittings straight away, I'll often suggest laying the ducting during the build so the lights can be added later without disturbing anything.
What do I need to know about safety and installation?
A few practical points to raise with whoever installs your lighting:
Outdoor electrical work should be carried out by a qualified electrician, preferably with prior outdoor experience and mains work in a garden needs to comply with Building Regulations.
Many garden systems are low voltage (12V) running from a transformer, which is safer and easier to adjust or extend as plants grow.
Fittings need a suitable IP rating for where they sit. Lights set into the ground or near water need a much higher rating than those under a sheltered pergola. IP65 is best to give peace of mind.
LED fittings use very little electricity and last for years, so running costs are low.
Solar lights have improved, and they are handy where cabling is impossible. Although they're less reliable in a shady city garden in winter, which is exactly when you need them most.
How do I light a garden without harming wildlife or the night sky?
This matters a great deal to me, and happily the wildlife-friendly approach is also the better-looking one. Bats, moths, hedgehogs and birds all depend on darkness, and too much artificial light disrupts their feeding and navigation.
My starting point is dark-sky friendly lighting. The idea is simple: light only what you need, only when you need it, no brighter than necessary, in a warm tone, and with fittings shielded so the light points down and not up or sideways. It protects the night sky, saves energy, stops light spilling into neighbours' windows, and it's the approach I prefer to design with. In practice that means:
Use less light, and only where it has a purpose.
Choose warm-toned light, which disturbs insects and bats less than cool white or blue-toned light.
Aim light downwards where you can, and shield fittings so nothing spills into the sky or next door's bedroom.
Keep ponds, hedges, bird boxes and the wilder corners dark.
Put everything on a timer or switch so the garden is dark when you've gone to bed.
A garden with pools of soft light and plenty of shadow is more atmospheric for you and far kinder to everything else that lives there.
Common garden lighting mistakes
One bright floodlight on the back of the house, which flattens everything and dazzles anyone looking towards it.
Runway lighting: evenly spaced lights marching down both sides of a path.
Too many fittings, so nothing stands out.
Cool white or colour-changing lights that fight with the planting.
Visible fittings and glare at eye level.
Leaving lighting until the garden is finished.
How can a garden designer help?
Lighting works best when it is designed with the garden, not added to it. When I draw up a layout I'm already thinking about which tree will be lit, where the evening seating sits, how the garden will look through your glass doors at night and where the cable routes will go. If you are mid-renovation, that is the ideal moment to talk, as the electrician can leave a supply and switches ready for the garden before the kitchen is finished. That is then set out in a lighting plan your landscaper and electrician can price and install from, so nothing is left to guesswork on site.
Whether you are starting from scratch or want an existing garden to work harder after dark, I offer garden design London homeowners can use for the whole project or simply for a session of advice.
Frequently asked questions
How many lights does a garden need? Fewer than you think. Most small and medium gardens look best with three or four lit features plus low-level light on steps and paths.
What colour light is best for a garden? Amber, at around <2200K for the most eco friendly option, or Warm white, around 2700K. It flatters planting and materials and is less disruptive to wildlife than cool white.
What is dark-sky friendly garden lighting? Lighting that is warm in tone, low in brightness, shielded so it points downwards, and switched off when not in use. It reduces light pollution and is far less disruptive to bats, moths and birds.
Can I add lighting to an existing garden? Yes. Spike lights in borders and low-voltage systems are the least disruptive options, as cables can be hidden in planting without lifting paving.
Is garden lighting expensive to run? No. Modern LED fittings use very little electricity, and timers keep usage down further.
Do I need an electrician for garden lighting? For anything wired in, yes. Use a qualified electrician who can certify the work.
