18/2awg solid wire for QB hookup

[PLantAsEED]

Built a QB fixture to run 680w. Have the drivers outside of the tent and the boards wires using 18/2awg solid core “bell” wire. It only has a voltage rating of 150v should this be a concern.
Going from drivers 17awg to 16/2awg lamp lighting stranded to 18/2awg solid core on the QB.

IF it's designed with a larger wire they did that on purpose. The #18 will heat up more and the insulation could fail causing a short. I don't normally work with electronics but I wouldn't replace a # 12 ( for 20amp) with a #14 ( 15 amp) and fully load the circuit. it will work but the wire will get hot.

Issue solved. Disregard thread. I was not thinking. Only running off 110/120v outlet.
