Choose Your Low Voltage Lighting Products

You've thought about your low voltage lighting and now need to choose what you need.

Just work through our simple three stage 'lighting plan' described below.  

IMPORTANT: Decide where you want to place your light fittings (spotlights etc.). It helps you choose in Stage 3 what cables will be needed to run from your mains 230v electricity supply.  

NB: All light fittings have a 'lead cable' attached and that cable connects to the main connector cable. This allows some flexibility in the final positioning.

We'd be pleased to help if you are unsure.  Draw a rough sketch of the garden or outdoor area and either scan it or take a photograph from a smartphone then email it to us at  We'll gladly help design or check your cabling runs.  Or have a look at our 'Example Sketch for Cable and Connectors' page. 

We can also advise on where to run the cables, will your cables be appropriate and is there a better or cheaper alternative.

Stage 1 - Choose Your Light Fittings (e.g.spotlights, post lights, wall lights)

Firstly, decide what light fittings you want (Stage 1). See our spotlights, post lights, decking lights etc in our All Products section

Once you have decided on the fittings you like, make a note of the electricity each LED light bulb fitting uses.  It's shown as 'watt's' in the product description.  

Then add up the total units of electricity (in watts) that all the light fitting bulbs will use.  Don't worry about remote controllers and cables at this stage.

Once you have the total 'watts' go to Stage 2 - Choose The Transformer.


Stage 2 - Choose Your Transformer

Now that you know what electricity ALL your light fitting bulbs will use then you can choose the transformer you need (Stage 2).

The transformer must be bigger than the total of all the watts.  

We like to give a little leeway here.  So as an example, if the total number of watts you will use adds up to 56W then we wouldn't choose a 56W transformer but a transformer with a greater maximum output such as the 108W transformer.  The reason is to allow the transformer to work at slightly less than it's maximum capacity.  

If your total is more than the largest transformer of 108 watts (or very close), then see if you can split your cables (circuits) into more than one run and then add another transformer.

Stage 3 - Choose Your Cables

Then decide on the cables and any connectors you need (3).

Bear in mind most light fittings have a 'lead cable' so your cabling run doesn't have to be measured to the millimetre!  You can move the fittings around even when they have been cabled-up so you are definitely not fixing your plan 'in concrete'!

Make sure you have thought about the light fitting spacing, where the cables will run (e.g. around bends and corners or down walls).  That will give an overall picture for the types of cables needed and and their length.

Remember your cable layout can use 'cable dividers' (connectors that take one cable and 'divide' the electricity supply into separate cable runs).

If you use the most powerful transformer together with the thicker cabling then you should be able to have a cable run of about 80 metres.  If in doubt then split the circuit and add another separate cable.

If you want to extend the run but do not require connection points for light fittings then an extension cable can be used.

If in any doubt, drop us an email with a note.  If you can draw a rough sketch of the garden or outdoor area and either scan it or take a photograph from a smartphone then email it to us at
