A pool light that won’t turn on is more than a looks problem. It can mean a burned-out bulb, but it can also mean water got into the fixture or a wire went bad. NextGen Pool Care repairs and replaces pool lights for homes and businesses across the Valley. Our own repair techs do the work, and we can swap an old bulb for a new LED light while we’re there. Call (623) 526-4945 if your light is out, flickering, or tripping a breaker.

Turn It Off First

Before anything else, a quick safety note. Pool lights run on power and sit under water. If your light is flickering, has water inside the lens, or keeps tripping the breaker, turn it off at the switch and leave it off. Don’t swim with a light acting up. Then call us.

Pool lights should be on a GFCI. That’s a special outlet or breaker that cuts power fast if something goes wrong. Many older pools in Phoenix don’t have one, or have one that no longer works. We test it on every light call.

What Usually Goes Wrong

Here’s what we find most often when a pool light quits, from the most common to the least:

Problem	What you see	The usual fix
Burned-out bulb	Light just won’t come on	New bulb, or switch to LED
Water in the fixture	Fog or water inside the lens	New gasket, or a new fixture if it’s rusted
Bad GFCI or breaker	Light trips the power, or nothing at all	Test and replace the GFCI or breaker
Worn wiring	Light flickers or works only some days	Repair or replace the wire
Loose fixture	Light hangs out of the wall	Reset it in the niche with a new screw
Bad transformer	Low voltage lights all go dark	Replace the transformer

Most of these are fixed in one visit. If we need to order a part, we’ll tell you when it will be in.

Do You Have to Drain the Pool?

Almost never. A pool light sits in a round hole in the wall called a niche. The cord has extra slack coiled behind it. To change the bulb or the fixture, we take out one screw, pull the light up to the deck, and work on it there. Then it goes back in the wall. Your water stays in the pool.

The one time draining comes up is when the niche itself is cracked or leaking. That’s rare. If it happens, we’ll talk it through with you and see if it makes sense to do it along with an acid wash or drain and refill.

Switching to LED

If your pool still has an old white bulb, the next time it burns out is a good time to go LED. Here’s why owners in the Valley make the switch:

• Lower power use. LED lights use a lot less power than old bulbs.
• They last longer. You won’t be pulling the light out every couple of years.
• Colors. Most LED pool lights can change colors and run light shows.
• Less heat. Old bulbs run hot, and that’s hard on the gasket.

Many LED lights can also hook into a control panel, so you can turn them on from your phone. If you want that, our pool automation team can set it up. Most of the lights we work on are Pentair, Hayward, or Jandy, and we can match a new light to the system you have.

What About Spa Lights and Yard Lights?

We fix spa lights the same way we fix pool lights. For yard lights or deck lights that aren’t part of the pool, call an electrician.

For pool wiring, our repair techs handle most standard work, like the wire from the light to the switch and the GFCI. If a job needs bigger electrical work, like a new circuit or a panel upgrade, we bring in a licensed electrician. We won’t try a job we’re not sure of.

Common Questions

Why does my pool light have water in it?

The rubber gasket that seals the lens wore out or slipped. This is common on older lights and on lights that ran hot for years. A wet fixture should stay off until it’s fixed. Sometimes a new gasket does it. If the inside is rusted, it’s time for a new fixture.

My light works some nights but not others. What’s going on?

That’s usually a loose wire, a bad connection in the junction box, or a GFCI that’s starting to fail. It can also be a timer or control panel setting. We’ll test each one until we find it.

Can I change the bulb myself?

Some owners do. But you’re working with power and water, and the gasket has to seal just right or the light will leak. If you’re not sure, it’s safer to let a tech do it.

Is a pool light leak a water leak too?

It can be. The conduit behind the light niche is a common spot for pool leaks. If you’re losing water and your light is old, have it checked. Our leak detection page has a simple bucket test you can try at home.
