Light Fixtures and Old Electric Wire Ratings
Electrical Current Rating of Electrical Wires for Light Fixtures If the home electrical wiring is original then the circuit wiring should be fine and rated for 15 amps minimum. This can be verified by identifying the circuit that the light fixture will be installed on and check the circuit or fuse rating, which should be either 15 or 20 amps, as installed. Because the light fixture has 18 gauge AWG wire this would indicate that the wire size is smaller and the amperage of the light fixture will be under 15 amps.

Often, smaller wire is rated for 300V, ...
Does copper have resistance?
Although it’s an excellent conductor, copper does have inherent resistance. The longer your run of cable, the more resistance (measured in ohms) you’re going to see on your circuit – just due to the cable itself. Also, as your wire gets smaller, resistance increases, since there is a smaller area for electrons to flow through. So why does this matter? Well, due to Ohm’s law, as resistance increases, voltage will decrease. If your wire is too small and the run too long, you may find that the 36V your driver is putting out is actually only 35V by the time it’s traveled the length of the wire. This voltage drop could cause problems in a constant voltage system where small changes in voltage can produce large changes in current.
