Your pool can be just as lovely after the sun goes down
Some of the best moments with a pool happen in the evening. The garden goes quiet, the air is still warm and the water glows softly under the stars. Good lighting makes all of that possible.
Today, most new pools are lit with LED pool lights. They’re bright, efficient and long lasting, and they offer far more choice than the older bulbs many pools used to have. You can keep things simple with clear white light, or bring in colour for parties and special occasions.
Lighting is also about more than looks. It helps you see the water clearly, find the steps and move around the garden safely. Planned well, it becomes one of the features you’ll enjoy most.
What you’ll find in this guide
We’ll explain how modern pool lighting works, the choices you’ll face and how to decide where lights should go. We’ll also cover controls, safety and what to do if you’d like to upgrade an older pool.
Why LED pool lights have become the usual choice
Not long ago, most pools were lit with halogen or incandescent bulbs. They did the job, but they had their drawbacks. LEDs have changed things for the better.
They use less energy
LEDs turn more of their power into light and less into heat. That means they generally use noticeably less electricity than older bulbs to give a similar amount of light. Over the years, that adds up.
They last much longer
A good quality LED is designed to last for many years of normal use. That means fewer replacements, and less need to drain water or work on the light fitting.
They run cooler
Because LEDs produce less heat, they tend to be kinder to the light fitting and its seals. This can help reduce wear over time.
They offer more choice
With older bulbs, colour usually meant a coloured lens over a white light. LEDs can produce a wide range of colours on their own, and many can switch between them at the touch of a button.
They make the water look better
Modern LEDs give a clean, even light that makes the water look clear and inviting. They show off the pool shape and finish in a way older yellowish bulbs often couldn’t. Even a simple white setting can make a real difference to how the whole garden feels after dark.
They’re easy to control
Many modern lights can be dimmed, set to change colour or linked to a timer. Some can be controlled from a remote or an app, so you can set the mood without leaving your lounger.
Choosing between white and colour changing lights
This is usually the first decision people make. Both have their place, and many pools use a mix. Most LED pool lights now come in both versions, so you won’t be short of choice.
Clear white light
White light gives a clean, crisp look that suits almost any pool. It shows off the colour of the pool shell and makes the water look fresh and inviting. Warmer whites feel softer and more relaxing. Cooler whites look brighter and more modern.
Colour changing light
Colour changing lights let you choose a single colour or run a sequence of shades. Soft blues and greens feel calm. Warmer tones feel cosy. Brighter shows can be fun for parties or children’s birthdays.
Getting the balance right
Colour is lovely, but it’s easy to overdo it. Many owners find they use white or a single calm colour most evenings, and save the shows for special occasions. Choosing lights that can do both gives you the most flexibility.
Picking the right white
White isn’t just one colour. Warm white has a slightly golden tone that feels relaxed and flattering. Cool white has a blue tint that looks crisp and modern. Neutral white sits in between. If your garden lighting is warm, a warmer pool light often helps everything feel like one scheme.
Think about the pool finish
The colour of your pool shell affects how the light looks. A pale finish reflects light and gives bright, clear water. A darker finish creates a deeper, more dramatic glow. It’s worth asking to see examples of your chosen finish lit at night.
Planning where LED pool lights should go
Placement makes a big difference to how your pool looks and feels. A few well placed lights often look better than lots of badly placed ones.
Plan lighting early
The best time to decide on lighting is while the pool is being designed. Fittings, cables and controls can then be placed exactly where they work best. On a one-piece pool, the light positions are usually agreed before installation, so the finished result looks neat and considered. Adding lights later is possible, but it’s easier to get right from the start.
How many lights you need
The number depends on the size and shape of your pool, the brightness of the lights and the effect you want. A small pool may only need one or two. A larger or more complex shape may need more to avoid dark patches.
Which walls to light
Lights are usually fitted into the pool walls, below the waterline. Where possible, it’s often best to point them away from the main viewing area, such as the house or terrace. This reduces glare and lights the water evenly without shining straight into people’s eyes.
Lighting steps and features
Steps, benches and entry points are worth lighting for safety. Small feature lights can also pick out water features, spillover edges or a swim spa area. They add interest and help people find their way in and out.
Lighting the garden around the pool
Underwater lighting looks best when the garden around it is lit too. Soft path lights, uplighters on trees and low wall lights all help. Keep garden lighting gentle so it doesn’t compete with the glow of the water. Our guide to pool landscaping has more ideas for the space around your pool.
Thinking about neighbours and wildlife
Bright light spilling over fences can bother neighbours and disturb wildlife. Point lights downwards where you can, use warmer tones in the garden and switch everything off when you head indoors.
Controls that make lighting easy to enjoy
The best lighting is easy to use. If it’s a chore to switch on, you won’t use it as often. Happily, LED pool lights are well suited to simple, flexible controls, from a single switch to your phone.
Simple switches and remotes
Some people like a simple switch by the back door. Others prefer a small remote to change colours and brightness from the poolside. Both work well.
Timers and schedules
Timers can switch lights on at dusk and off at a set time. You can adjust the schedule as the evenings draw in or grow longer through the year. That means the pool always looks welcoming when you get home, without lights being left on all night.
App and smart control
Many modern pool systems let you control lighting, heating and other equipment from your phone. You can change the mood from the sofa or check everything is off from bed. Our guide to smart pool control explains how this works in plain English.
Setting scenes
Some systems let you save favourite settings as scenes. You might have a calm scene for quiet evening swims, a bright one for cleaning or checking the water, and a colourful one for parties. One tap brings back the look you like, without fiddling with settings each time.
Linking lights together
Some lights can be synchronised, so they all change colour at the same time. This gives a smoother, more polished effect than lights changing at random.
Keeping LED pool lights safe and working well
Lighting sits underwater, so safety and quality matter. A little care keeps everything working properly for years.
Leave the electrics to qualified people
Pool lighting must be installed by someone suitably qualified, following the wiring rules for pools and their surroundings. Underwater lights typically run at a low, safer voltage. Never try to open or adjust a pool light yourself.
Choose lights designed for pools
Only use fittings made specifically for underwater use in swimming pools. They’re built to be watertight and to cope with pool water over long periods.
Look after your water balance
Well balanced water is kinder to every part of your pool, including light fittings and their seals. Regular testing helps protect your equipment as well as your swimmers.
Keep the lenses clean
Over time, a thin film can build up on light lenses, especially if water balance drifts. A gentle wipe during routine cleaning helps keep the light bright and even. Use a soft cloth or brush, never anything abrasive that could scratch the lens.
Watch for warning signs
If a light flickers, fails, fogs up inside or shows any sign of water getting in, switch it off at the supply and stay out of the pool. Then ask a qualified engineer to take a look. We offer servicing and repairs if you need a hand.
Upgrading older pool lights
If your pool still has older bulbs, you may be wondering whether to switch. In many cases it’s very achievable.
Can older lights be converted?
Some older fittings can take a replacement LED unit. Others need a new fitting altogether. It depends on the type and age of your existing lights, so an inspection is the best starting point.
When upgrading makes most sense
A light failing is often a good moment to upgrade. So is a wider refresh, when you might also look at the pool surface, covers or heating. Our guide to pool refurbishment explains how to approach a bigger update.
Adding lights to a pool without them
Some older pools were built with no lighting at all. Adding lights is sometimes possible, but it can involve more work, because new fittings and cables need to be installed safely. It’s something we’d assess on site. If your pool is due a wider update anyway, it may be a good time to add new lighting as part of the same project.
What to expect
We’ll check your current lights and wiring, then explain your options plainly. If you’d like to compare a few choices, we’ll talk you through them and give you a tailored quote. Our guide to the latest swimming pool trends covers this in more detail.
LED pool lights questions we get asked a lot
Are LED lights better than halogen for pools?
For most pools, yes. LEDs generally use less energy, last longer and give you far more choice of colour and control.
How long do LED lights last in a pool?
A good quality LED is designed to last many years of normal use. Water balance and how often the lights are used can make a difference.
Can I change the colour of my pool lights?
Yes, if you choose colour changing lights. You can usually pick a single colour or run a colour sequence.
How many lights does my pool need?
It depends on the size, shape and finish of your pool. We’ll recommend a layout that lights the water evenly without glare.
Can I replace my old pool lights with LEDs?
Often, yes. Some fittings can take an LED unit, while others need replacing. An inspection will tell you which.
Are underwater lights safe?
Yes, when installed by qualified people using fittings designed for pools. Switch them off and call an engineer if you ever notice a fault.
