It is important to use the correct type of wiring for your low voltage deck lighting system. Most LED lights use 18/2 gauge wire while most Incandescent lights use 12/2 gauge wire. You will need to match the polarity of the wire to the lights. Most wires are split into a smooth black wire and another wire with white lettering or ribbing. You must connect the matching wires to create a working connection.
You will need to create a circuit by connecting your lights with wire in a routered cavity in the railing or under the deck to protect them and hide them from view. Aurora pigtail wires can be used to connect side mounted rail lights to the main cable line. Voltage drop can occur from line loss over a long line of lights. The position of your transformer and lights layout will create a low voltage circuit. We recommend that you install your lights in a looped circuit for the best results. A straight line, T, and split load installation can be used for alternate circuit layouts. LED lights must be wired in parallel not in a series and polarity must be maintained throughout the lighting system.
