A retrofit pool light is designed to replace your existing light without the need for new cables, or structural work. It makes use of your current housing and wiring, allowing a new light to be installed usually without lowering the water level.*

The Spa Electrics RETRO® Series makes this process simple, fast, and reliable. In many cases, our lights can be fitted in as little as 15 minutes — often without anyone needing to get into the pool.

*While most replacements are straightforward, some setups can vary. Start by checking the RETRO Replacement Guide, and if you’re unsure, contact Spa Electrics for further advice.

No draining required. One of the biggest advantages of the RETRO® Series is that it can often be installed with the pool full of water.* The light should be in a serviceable location — typically not deeper than 400mm below the waterline, with enough access to reach in and remove or install the light safely.

*Some exceptions apply, particularly for vinyl and fibreglass pools. Check the RETRO® Replacement Guide for more details or contact Spa Electrics for advice on your specific setup.

In most cases, no. RETRO® lights are designed to work with your existing cabling. Most common exceptions are if the cable is damaged, unsuitable for underwater use or outside the recommended size range. Check the product installation manual for cable specifications, or contact Spa Electrics or your pool professional if you’re unsure.

No — in most cases you can use any iron-core 12V AC transformer, provided it’s suitable for outdoor use and in good working order.

For the best performance and long-term reliability, Spa Electrics recommends our purpose built transformer range, designed specifically for pool lighting.

⚠️ Important: DC power supplies cannot be used with RETRO® and must be replaced.

Most installations take less than an hour per light, some as little as 15 minutes. RETRO® products are designed to use your existing cable and housing, so there’s no need to replace cables, empty the pool, or drill new holes in most cases*.

*While most replacements are straightforward, some setups can vary. Start by checking the RETRO Replacement Guide, and if you’re unsure, contact Spa Electrics for further advice.

RETRO® lights are low-voltage and designed to be DIY-friendly - however, due to recent QLD regulatory changes, DIY installation is not permitted in Queensland, Australia.

Spa Electrics provides step-by-step installation guides and videos to help, and if you’d prefer not to tackle it, your local pool professional can assist.

⚠️⚠️Important : If your transformer has been hardwired to mains power, a licensed electrician must complete the work. Spa Electrics also does not recommend using power tools during installation which can cause faults and damage to light components. ⚠️⚠️

Installation regulations vary by state. In QLD, installation must be carried out by a licensed professional.

Yes — and it’s one of the most popular upgrades pool owners make. The RETRO® Series lets you swap out hot, power-hungry halogen lights for long-lasting, energy-efficient LEDs. You’ll enjoy vivid colours, lower running costs, and no more frequent bulb changes.

Check the Retro Replacement Guide for compatibility.

Compared to a typical 100W halogen, RETRO® LEDs use around 15W — that’s up to 85% less power. This means you can run your lights for longer without worrying about electricity costs, while also reducing your environmental footprint.

Yes. RETRO® lights offer industry-leading brightness. However, the overall effect depends on the number of lights, their placement, and your pool’s surface colour — darker finishes absorb more light than lighter ones.

If your pool has a dark tile or pebble finish, you’ll achieve the best illumination with our True White (4000K). For more flexibility, MULTIPLUS gives you a full range of colour options.

Every pool is different, so while RETRO® is among the brightest on the market, results may vary. For support, speak with your pool professional or contact Spa Electrics for tailored advice.

As often as you like! RETRO® Series lights are built for regular use — and it’s important to switch them on for at least 30 mins per week, even during winter or when the pool isn’t in use.

Here’s why: if underwater lights sit idle for long periods, moisture can naturally build up inside the fitting. When the light is running, it gently heats and removes this moisture. If the light isn’t used often enough, that moisture can linger and shorten the lifespan of the light.

Regular operation helps keep them healthy and lasting longer!

LED lights are low-maintenance, but their longevity depends on three key factors:

• Proper installation – when installed correctly, your RETRO® lights will perform as intended and provide lasting reliability.

• Regular use – running your lights for a minimum 30 mins per week helps remove moisture and extend their life, while infrequent use can shorten it.

• Balanced pool chemistry – Spa Electrics strongly recommends maintaining pH between 7.2 and 7.6, tested weekly, to protect your lights and other pool components.

If you ever have an issue, Spa Electrics offers after-sales advice and troubleshooting to keep your pool shining bright.

Most likely, yes. Spa Electrics designed the RETRO® range to replace a wide range of major brand pool lights, including Astral, Aquaquip, Waterco, PAL, and others. This broad compatibility is one of the reasons RETRO® is a leading choice for pool owners across Australia and New Zealand.

For specific model compatibility, check our RETRO Replacement Guide or contact Spa Electrics for advice.

It depends on what you’re replacing. Use our RETRO Replacement Guide to match your current light with the correct RETRO® model. Or, simply send a photo of your existing light to info@spaelectrics.com.au and our team will help you identify the right product.
