These examples illustrate various ways to wire up the Nano Spot Miniature Spotlights. All of the examples show a 12V 1Amp power supply and two Nano's. A single 12V 1Amp power supply can power up to 33 total Nano's. You can simply wire more in just like the two that are shown.
The final example shows how you can cut off the adapter from the end of the power supply cable and then use wire nuts to directly connect the bare wires on the Nano's.
You can extend the length of wire on the Nano's by using "22 Gauge Wire"
