sorry for raising this thread from the dead but what are the normal increments for adjustment? Like 1/4turn or 3 turns at a time? just for general guidance...
Older thread, but figured I would post in case someone needed info going forward - I just did 2.8" Bils and it took aprox 6-7 turns to get lights back down to "normal" position - so appears to be about 2 turns per inch, give or take.
