Does anyone have one of their lights with this driver?
How does it work, like a linear driver that reduces brightness but in many small steps as the voltage of the battery falls, or does it stay in high, then go to medium, then to low as the voltage falls?
Many small steps
is there any advantage to it over a linear driver?
It gives slightly better runtime and in theory makes it easier to tell your batteries are running down. Here is a little graph selfbuilt did comparing modes on the original Predator.
excellent, thanks
I think you mean Viking
I saw at its specs about step stabilization.
