Greeting from Australia the land of 240V power.

I need help with a project. We have a bunch of 12V 10W LED outdoor floodlights for small signage applications.

The problem is we need a 20 meter 12V cable from the light to the driver that converts the 240V power to 12V.

The problem: The cable will drop in voltage by the time it gets to the 10W 12V LED floodlight, and then it wont work.

What wire can we use to make sure there is no voltage drop? Is there a way to calculate this.

Please note the wire needs to be 12V because 240V is just not an option due to safety regs on the 20 meters of cable.

your help would be great :)
