I was about to buy bunch of power cables for the lights and dimmers I've got on the way to me right now, and I see that I can buy these cables in 16 or 12 gauge versions. Any reason why I should buy one or the other? These will be going between the dimmers and the wall, and also between the lights and the dimmers.
And also, if I could slip in a newbie question... since my lighting setup has not arrived yet, how long are the power cables coming out of the lights, in my case the ADJ Par-38Bs?
