Step 2 - Choose a transformer
As our system is 12 volts, it requires a transformer to convert the mains 240 volt to 12 volt. The total wattage of your lights will determine what transformer you'll need. To calculate this, add up the wattage of each light plus any switching device and select a transformer with a higher wattage/capacity. Just remember that the 60W & 150W transformers have a maximum capacity of less 20%, the 60W becomes 48W and the 150W becomes 120W. The 24W transformer can be loaded up to it's full capacity.
Tip: We recommend allowing for a few extra lights on the transformer in case you want to add to the system later on.
