I am running two 450w GE landing lamps on my car, they have 6AWG wire which i THINK may be overkill, i want to redo my wiring to clean things up a bit. With that said, they are designed for 16.5v, and i realize a car is 12v.....so for one thing, how would you end up figuring out how many amps you now would accommodate for? I hope that makes sense, i know they will not be as bright if they arent powered by a true 16.5v, but the car when running is typically 14.3v.
Ok so after figuring out the new wattage, divided by voltage (no idea if you would use 12v or the 14.3), you get the amperage, i understand that....but so many wiring charts show different size requirements, some say 8AWG, 10AWG, etc....so i have no clue if i can get away with 10AWG wire.
Thanks for any advice!
