tools and materials needed to install deck lights

1. Make a lighting plan

First, draw a sketch of your deck. Then, work out where you want your lights to go on the boards, including any steps.

2. Measure and mark

Take measurements of your deck, so you know how many lights you’ll need. Then, mark out where your lights will go, spacing them out evenly.

3. Choose your lights

Before you purchase any deck lights, work out what type of lighting you want. Choose softer, warmer lights for some ambience or add some fun with colourful lights.

4. Remove boards

Once you’re ready to install the lights, you need to remove the boards on your deck. This is so you can reach inside and install and connect all the lights. We’ve got a modular deck, so we’re taking off the whole panel.

5. Drill the holes

To drill your holes, choose a spade drill bit that matches the size of your deck lights. It needs to be about 2mm wider than the light. Then drill holes in the marks you made on the boards.

6. Insert and connect lights

Now, insert the lights into the holes and connect all the cords at the back of each light. Then, connect the end of the cable to a power source. You’ll need to get an electrician to do this for you.
