I have a circuit with a power supply of 58V @ 1A so the total wattage is 58 Watts. The wire will be running about 20 feet from power supply to led. What gauge wire should I use?

The LEDs will be running @750mA and a string of 16 LEDs each with a fV of ~3.5V.To be determined by the load, so what will the load current be? Additionally, just a single LED? Pretty high voltage for a single LED.
I would like to minimize the drop as much as possible because I do not have that much overhead.How much voltage drop can you tolerate?

Where is the current-limiting for the LEDs? If you are using a ballast resistor, I submit that you don't care what the voltage drop along the wire is, as long as the wire does not self-heat significantly. You can always reduce the ballast resistor slightly to make up for the wire resistance; at only 750mA you can use #22 to #26 AWG.

Probably, a familiar term to me.Is "core" a british term?
