The Techmar garden lighting system is incredibly easy to install without the need for an electrician. Installing the system is as as easy as 1 2 3. The following information will guide you through the these three key elements.

1. Choose Your Lights

There are approximately 120 lights to choose from in the Techmar range. At time of writing, we are the only supplier of the whole Techmar range.

Choose your lights

While choosing your lights you should try to think about what you are trying to achieve. Is that lighting supposed to be purely aesthetic, is it supposed to illuminate a large area, a single plant or a feature? To read more about choosing your actual lighting please read our garden lighting guide.

2. Choose Your Transformer

Once you have looked through the site and picked the garden lights you want to use, your next task is to choose the correct transformer to use.

Choose your transformers

There are three transformers available, 22W, 60W and 150W. To choose your correct transformer, all you have to do is add up the total wattage of your lights. To find the wattage, simply look at the product description and find the light source included. So for example the Alder spotlight pictured above says the following.

Light Source Included: Power LED unit Warm White 12V 2W G5.3 base

So therefore the wattage is 2W.

Once you have added up all the wattage of your garden lights, you then simply pick a transformer that suits that total wattage. It's important to remember that you may want to add to your lighting in the future so ensuring there is some spare capacity is a really good idea.

As an example, the lights in the top section of this guide breaks down as following.

  • Alder Spotlight (2W) x 4 - Total = 8W
  • Arco 40 Post Light (3W) x 4 - Total = 12W
  • Deimos Wall Light (1W) x 2 - Total = 2W

So for this example your WATTAGE GRAND TOTAL would be 22W. Even though there is a 22W transformer available we strongly recommend that you try to leave 20% of the capacity if possible as this will extend the life of your transformer. So therefore in this case, a 60W transformer would be the correct choice. This obviously would allow for further lights to be added in the future as previously mentioned.

3) Choose Your Cabling

So now we have our garden lights and our transformer, we need to connect everything up. There are two main cables, 3 extension cables and a 3 way splitter available. Although this sounds limited, we plan peoples cabling for them every week and to be honest, we have never been unable to achieve peoples plans.

Choose your cables

The cabling you choose is determined by the position of your garden lighting and your power source. The aim is simply to join up all the points using as little cabling as possible. Again, many of our customers come back and added extra lights. This is easily achieved though in most cases by using a three way splitter (shown above) so adding extra capacity on the main cables usually isn't something you really have to worry about.

Something most people forget is that the lights themselves come with a cable which is usually 1m, 1.5m or 2m. This information can again be found on the lights description. So using the Alder garden spotlight again as an example you would be looking for the cable information.

Cable: 1 metre SPT-1 with connector


That's pretty much it! Simple to install, safe, 12V plug and play lighting, that really can be installed by anyone without the need for an electrician.
