I have asked this of 4wder's & they really don't know, probably because they don't use them much. I'm wanting to get a 40 inch sized bar & wan't to run it for many hours at a time on long drives. I assume the expensive bars can do this frequently without problems but what about the cheap units?
For example cheap 400watt 40-50 inch size bars sell for 250-300 USdollars. Yet some brands of same size can go up & over 1500 dollars.
I have also read the cheap units are significantly below their advertised output to prevent heat damage so maybe they are fine?
Finally do you have upgrade vehicle alternator? Mine is 90A & with a 30-40amp draw from the light bar surely you must, i have read about the alternator burning out & the starter battery going flat because the typical driving rpm is not enough for alternator.
please advise thanks.
