Light along the length, not across it
Fixtures in a long wall throw light down the pool. Set in a short end wall, the beam runs out before it reaches the far end.
Pool Lighting
An evenly lit pool changes the backyard after dark. Plan the fixtures, colors, and coverage around the way you use the pool and spa.
What It Is
What does pool lighting do?
Lighting is what makes a pool a place after dark rather than a dark shape in the yard. Underwater LEDs light the water from within, so the whole pool glows rather than being lit from above, and colors change on demand. Set right, the pool becomes the brightest thing in the backyard and the reason anyone is outside at nine at night.
It's also the equipment people most often under-buy, and the mistake is permanent.
We install Jandy as our primary line.
How many, and where
One light in one wall is the default on a cheap build, and it produces exactly what you'd expect: a bright patch near the fixture and a dark far end. Getting this right is about coverage, not brightness. The rule: more, smaller lights beat one big one. Even coverage looks better than a single bright source, and it's far cheaper planned than added.
Count the obstructions, then add lights
Every bench, step, sun shelf, swim-out, raised wall, and spa dam blocks light and casts a shadow behind it. A simple rectangle may be fine with two. A pool with a shelf at one end, a bench along one side, and a raised spa needs more, because each of those creates a dark zone.
Aim away from the house
Fixtures pointing back at the patio put glare in the eyes of everyone sitting there and light the underside of the surface rather than the pool.
Light the spa separately, and give steps and shelves their own fixtures
A spa is a small volume with its own walls; steps and shelves are where people walk and exactly where a shadow is least welcome.
Your options
Infinite WaterColors
Jandy's current top LED line, in nicheless and niched versions. Unlimited color range rather than a fixed set of preset colors, plus QuickConnect technology and a native Amazon Alexa skill for voice control.
WaterColors Nicheless with HydroCool
Jandy's nicheless LEDs with thermal management. Fit a standard 1½-inch return fitting rather than needing a large niche, so they suit complex pool shapes. HydroCool moves heat into the water so the light runs cooler and lasts longer.
Color or white
RGBW color-changing, or fixed warm white. Color is what most people choose. Warm white is calmer and suits a more architectural look.
Wattage and quantity
Smaller fixtures used in greater numbers, or fewer larger ones. Several smaller lights give more even coverage than one bright fixture.
Placement
Long walls, spa, steps, and sun shelf treated separately. Where the fixtures land decides whether the pool reads evenly lit or patchy. Settled on the plan, not on site.
Why QuickConnect matters
Replacing a failed underwater light traditionally meant dropping the water below the fixture or getting in to pull it, slow, awkward, expensive. Jandy's QuickConnect design lets a technician lift the light above the waterline to work on it, turning hours into a straightforward job. Lights are the equipment most likely to need service during a pool's life, and making that easy is worth more than another color mode.
Lighting FAQs
Fixture counts, colors, service, and planning for future upgrades.
How many lights does a pool need?
More than one, almost always. A simple rectangle may work with two in the long walls; anything with a shelf, bench, spa, or raised wall needs more, because each of those casts a shadow. Even coverage beats brightness.
Where should pool lights go?
In the long walls, aimed away from where people sit, with separate fixtures for the spa, steps, and shelf. Lights in an end wall leave the far end dark.
Can I add pool lights later?
Yes, but it means cutting the shell and running new conduit, which costs far more than the fixture. If there's any chance you'll want another light, run the conduit during construction.
What should I know about running costs and replacement?
LEDs use a fraction of the power older lights did and last far longer, so running cost is negligible and replacement is rare. What eventually fails is usually the fixture, not the bulb, which is why serviceability matters.
Will the colors look the same in every pool?
Colors look different in your pool than in a showroom. Water depth, interior finish color, and how much ambient light is around all shift what you see, a blue over a dark pebble finish is a different blue over white plaster. Judge colors in a finished pool at night, not on a sample.
What should I check on a lighting proposal?
Count the lights on the proposal and picture the pool at night. If there's one fixture for a pool with a shelf, a bench, and a spa, that's a pool that will have dark corners forever. Adding a light later means cutting into a finished shell and running conduit, the same fixture costs a fraction of that at build time.
Should I plan for lights I might add later?
Second, check the conduit even for lights you're not buying yet. Running an empty sleeve to a future fixture location is nearly free during construction and is the difference between a simple upgrade and a demolition job.
What should I ask any builder?
How many fixtures, and can you show me where each one lands? What's behind the bench and the shelf at night? Is there conduit for lights I might add later?
