Garden Light Kits

To create a gorgeously lit garden with our high quality lights, you’ll need more than just the lights themselves. Exactly what you’ll need, and how many, will depend on the size of the space you’re trying to light, and how many lights you’d like to use to achieve this.

What Do I Need?

After selecting the number of lights you’d like, you’ll need the items listed below to make it all work.

• 1 x Transformer
• Cable from the transformer to the first light
• Cable from light 1 to light 2 etc (between lights)
• T-Joiners and Cylinder Joiners

Here’s a quick example of what a complete kit could look like to light up a garden bed along a fence, using 6 Apollo Brass Garden lights with 7 watt bulbs:

• 6 x Apollo Brass Garden lights
• 1 x 60 watt, 24v Transformer
• 1 x 20m of cable
• 1 x Cylinder Joiners
• 5 x T-Joiners

How do I know what size transformer I need?

When it comes to your lights, the wattage is determined by the bulbs you choose — 3W, 5W, or 7W. The transformer needs to be strong enough to handle the total wattage of all your bulbs added together.

From our example:

If you’ve got 6 x 7 watt bulbs, that’s 42 watts total. So you’ll need a transformer that can handle at least 42 watts, BUT! It’s always smarter (and safer) to leave some breathing room.

Instead of a 42W transformer, you’d go for something like a 60W transformer. That way it runs cooler, lasts longer, and can deal with any small voltage spikes or dips.

(And anyway, transformers come in set sizes. You usually won’t find one that matches your lights exactly, so it’s normal to go a bit bigger.)

To pick the right transformer, just add up the total watts of all your lights.

More examples:

6 x 7W bulbs = 42W → choose a 60W transformer.

10 x 3W bulbs = 30W → choose a 40W transformer.

4 x 5W bulbs = 20W → choose a 40W transformer.

12 x 5W bulbs = 60W → choose a 100W transformer.

20 x 7W bulbs = 140W → choose a 150W transformer.

Always choose a transformer that's a bit bigger than your total wattage.

Our garden lights work with both 12V and 24V transformers, but the main deciding factors are how many lights you're running and how far the cables need to go.

Pick 24V if:

• Your total cable run is longer than 10 metres (including spacing between lights).
• You are running 6 lights or more, especially if they're spaced out by 2–3 metres each.
• You want brighter, more consistent lighting across longer runs.
• You’re planning a large DIY or commercial project.

Pick 12V if:

• Your total cable run is under 10 metres.
• You have 4 lights or fewer, fairly close together (about 1-2 metres apart).
• You want a simple, small setup with short cable runs.

As a general rule, if you’re unsure, we recommend choosing 24v. It’s almost always more energy efficient, runs cooler, is more capable, and is less likely to result in issues with voltage drop over long cable runs where lights at the end can appear dimmer. Your lights will also be brighter overall with 24v. Both 12v and 24v are considered low voltage and pose no serious danger of electrocution. 

What About Cables?

All you need to do is determine how far the first cable needs to extend from the transformer (which is plugged into the wall) to the first light. 

Then, choose how many metres apart you’d like to place each consecutive light, select a length of cable to accommodate this, and cut to size.

We used 5 metres of cable from the transformer to the first light and then 3 metres of cable between each consecutive light in our example above. However, you can adapt these lengths to be as long or as short as you need. 

Remember that it's always better to have a bit of extra slack than not to have enough cable. Additionally, electrical signals can begin to degrade over long distances, so if you’re planning something large, why not speak to our helpful team, and we can best advise you about cabling for large projects.

And The Joiners?

The joiners are what connect all your cables together, and luckily, it's super simple. The cylinder joiners are for connecting two wires together, while the T-Joiners are for connecting two lengths of wire and a light. You can mix and match joiners as you need them; it comes down to how you want your lights placed in your garden. 

Can I Add More Lights Later?

Sure! As long as your transformer still has enough headroom to handle the increased wattage, you can add as many as you like down the track. 

If you think you might want to add more lights later, you can always overspec your transformer now by choosing one with a higher wattage to handle more lights in the future, so you won't need to buy a new transformer for additional lights.
