Pathway lights - 12v or 240v - any electricians/help?

[sidekickdmr]

I have about 100m of pathway I want to light.

All I want is a small little 2W LED spike light every 5 or so meters, so only 20 in total, and only about 40watts total too.

However with the length of run, and voltage drop, can I do that on a 12V system?

large transformer and large core cable may well help?

Saves having to buy armoured cable, pay a pro to instal it, and dig up 100m of solid stone path if I can.

Thanks

So if i understand that right

20 of these lights (60W)

Using this wire (2.5mm 2 core)

And this transformer (100W):

I may find the first LED is brighter and the last one dimmer but should work ok?

Problem solved, decided to go for commercial quality extendable 240V overhead festoon lights.

The extra cost of the hardware is offset by the lack of time/labour connecting and running cables

Thank you for the very detailed responses though, Pistonheads is great for this type of knowledge
