Stranded verses solid wire. Electrical current actually passes along the outer edges of a wire. Above a certain level of current stranded wire if more efficient for the same size wire. For a simple lighting system it really wouldn't matter. But there is an actual difference.
Stranded wire is used for one reason in autos and mobile applications, it’s flexible and will not break as easily as a solid core wire. It can take bending and vibration better. The power handling ability of one over the other never comes into play as all that is done to handle more power is to go with a bigger wire, not to pick solid or stranded over the other because it takes more current.
