Alright, let’s talk pool lights—specifically the ones that change colour. If you’ve got a pool in the backyard (or you’re thinking of putting one in), you’ve probably looked at ways to enjoy it after sunset. Traditional white lights are fine, but colour-changing LED pool lights? Yeah, that’s where the fun really starts.

So, what’s the big deal?

Here’s what matters: colour-changing LED pool lights aren’t just flashy—they’re smart, efficient, and way easier to deal with than you might think. You can set the mood for a relaxing night swim with blue tones, kick off a backyard party with a rainbow cycle, or even spice things up with a red glow that makes everything pop.

It’s kind of like when you swap out your regular lightbulbs at home for smart bulbs—you suddenly realise how much better things can be with just a bit of control and colour. That’s exactly what these pool lights do outside.

They save power (and your wallet)

Let’s cut to the chase: LED lights use heaps less electricity than the old-school halogen ones. We’re talking up to 80% less, depending on the setup. That means you can run them longer without worrying about spiking the power bill. And since LEDs last much longer—usually 30,000 hours and up—it’s not like you’re climbing into the pool with a screwdriver every summer to replace them.

In New Zealand, where electricity isn’t exactly cheap, this stuff adds up. You’ll find brands like Spa Electrics and Aquaquip over at places like Bunnings NZ or Paramount Pools—they offer durable LED options with good warranties.

Easy to control

One of the coolest parts? Most of these lights come with remotes or connect through apps. You can change colours, pick different light effects like fade or strobe, and even time them to shut off. Some top-end systems can even link with your home automation if you’re into that sort of thing.

Think of it like your TV remote for the pool. Push a button, and it goes from chill mode to party mode. Super easy, even if you’re not a tech whizz.

Do they fit your existing pool setup?

Here’s what you should do: check what kind of lights you’ve already got. If you’re running halogen lights, you’ll most likely need an upgrade, maybe even a transformer, because LEDs run on low voltage. But don’t worry—many LED pool light kits here in NZ are made to retrofit straight into existing fittings, so you don’t always need to dig up the pool wall. Handy, right?

Chat with your pool shop or sparky. Pool suppliers like Poolquip or Swimart NZ can size things up and help you pick a light that’ll work without ripping everything apart.

Should you DIY or get it installed?

Okay, here’s the thing—if the wiring’s already in place and it’s just about switching a light head, it’s doable if you’re confident. But if you’re starting from scratch or need transformer changes or anything electrical, just call a licensed tradie. Seriously, don’t muck around with electricity near water.

Plus, pros have tools to make it watertight, safe, and tidy looking. It’s worth it.

What colours and features to look for

Anyway, let’s talk colours. Most standard LED pool lights offer 7 basic colours with a few light modes—fade, transition, flash, etc. That’s usually more than enough. Some pricier models (like the ones from Spa Electrics you can find at Goldair Pool Products NZ) have a broader colour spectrum or syncing abilities so you can match multiple lights.

If multi-zones or syncing gets your attention, make sure the lights you choose are compatible out of the box—or you’ll end up juggling remotes or apps.

How many lights do you need?

Here’s a general rule: about one light for every 6–8 metres of pool length. For small plunge pools or spas, one quality light may be enough. For larger pools, two or more will give better coverage and cost less to run than one overpowered beam trying to do the job solo.

Oh, and placement matters—corner lighting cuts shadows, especially if you’ve got steps or interesting pool shapes.

Final thoughts? Just start simple. One solid LED light with a few colour modes can transform your backyard scene. Then, if it turns out to be your summer-night MVP, you can always add on from there.

So if you’re browsing local stores, check out Paramount Pools, Mitre 10, or Pool & Spa 2 in Tauranga for some solid options. Even Trade Me has good deals—just make sure you’re buying a reputable brand and not something dodgy that’ll blow out in a month.

Bottom line: colour-changing pool lights are fun, practical, and easier than you think to get going. Once you’ve had a swim under a soft purple glow with a cider in hand, you’ll wonder how you ever settled for plain white.
