The best thing to do is, learn how to do it right!!! You NEED to know how to calculate and USE voltage drop. When using line voltage, a loss of a couple of volts is nothing to worry about, but if you start out with 12 volts and you loose 2 volts, you don't have enough voltage to operate a lamp properly. I balance all of my lamps to 10.8 - 11.8 volts. If you can learn how to do this, use the very best equipment and stand behind your work (no matter what), you will be on your way.
