2.Wire size: The size of the wire has a great influence on the voltage drop. Therefore, the thicker the wire, the lower the voltage drop. On the contrary, the higher the voltage drop.
3.Wire length: Longer wires mean that the path of current flow is longer, so the voltage loss is also higher. You should reduce the length of the power supply as much as possible.
4.Load current:The greater the current, the higher the voltage drop. You should also carefully check whether your LED and led light driver can withstand large currents, we recommend 80% load is the best
