Control your RGB Colour Deck Lights with our Bluetooth Controller, or for advanced features and smart automation scheduling options, try our Wi-Fi Garden Light Controller (it’s even voice activated!).


Before you get drilling, planning out the correct spacing for your deck lights is vital. This will determine how many lights you require, and the length of cable needed to connect them to the controller. Our deck lights are automatically spaced out with up to 2m in-between each light. Plus, our Plug & Socket systems allows you to simply plug in and enjoy!

We suggest marking on your decking exactly where you want to have your lights and placing them out to ensure the spacing is correct.


Our new Spacer Cables allow you to add an extra 2m of length in-between your deck lights, or they can be used to branch your lights further away from the main lighting cable!

* We recommend not to use more than 5 of these cables in a single line to avoid wattage loss to your lights.


Now that your marks have been made, if you can, we suggest removing the panels you will be drilling into. This is so you can connect the cabling together underneath your deck. It also allows you to check that there are no other cables or pipes behind your deck. Remove the desired panels and drill the required holes into your deck where you marked.

Refer to our sizing chart above to determine the size of the spade drill bit you’ll need.

Push the deck lights and cables into the holes you’ve drilled, making sure the fixture is secured tightly with no more than a couple of millimeters to move. Ensure that each Deck Light is daisy chained together. To connect the starting light to your chosen controller, we have a range of connection cables available in various lengths.

Now that all of the deck lights are connected, you can place the decking boards back into their original position.

Note: We recommend no more than 12 deck lights to be daisy chained together. If your plan includes more than 12 Deck Lights, add an expansion tee and another length of connection cable from your controller to the next group of deck lights. You can read our help article about connecting multiple deck lights together here.

  1. I have bought 2 sets of deck lights and 1 controller box, 1 set of lights and controller are 2 pin and the other set are 4 pin is there any way to intergrate or do I need another controller?

    1. Hi Paul, it sounds like you have a 2-pin warm white controller, a set of 2-pin warm white lights, and a set of 4-pin RGB colour lights. Our RGB lights run on a 4-pin cable and will require an RGB controller.

    1. Hello, we wouldn’t recommend using an 18mm deck light in a 20mm hole. They will fall through and be difficult to reach. This will also affect the light they throw, as they will be sunken in the 20mm hole.

      We’d suggest enlarging the existing hole to 22mm and buying the 30mm Deck Lights for your project. You can enlarge the hole using a variety of methods, the the easiest would be reverse drilling. Fit the next larger bit into your drill. Next, flip the drill into reverse mode using the button above the trigger. With the drill turning counterclockwise, it greatly reduces the chance that the cutting edges of the bit will bite into the wood and cause tearout or scarring.

  2. Hi
    I’m assuming by the reply above, the deck lights can’t be removed without damaging them? We had the rgb lights installed by the landscaper and would have preferred white. If it’s not possible we’ll learn to live with.

    1. Hi Gavin, our deck lights can be easily changed or removed. However, you will need to make sure you have the correct warm white controller, warm white cabling and warm white deck lights to do so. We have an article available here that explains how to get the closest to ‘warm white’ using your RGB colour controller, this may be helpful if you do not wish to change your whole system. Please let us know if you have any other questions!

  3. DEck lights have been working fine for 1.5 years since install. One of the lights is now now illuminating like the others, how would I replace this light. All others are working fine. It definitely has not been running for more than 30,000hrs..

    1. Hi Kevin, thanks for your question and we are sorry to hear that you are having troubles with your Deck Lights. This issue may be caused by a faulty product, if you can please get in touch with our customer service team at they will be able to assist you with your lights. Thanks, Dayna.

    1. Hi Kelvin, all our lights have LED’s which equals to about 30,000hrs lifespan per light. It would be a long time before you had to change them unless there was a fault or you changed your mind. We recommned plugging in the lights before installing them to ensure they’re all working properly. Thank you!
