Just to clarify:
When you're in one of the new mode groups where everything is fully configurable, would you be able to select a lower mode group from those 2048, or would you be limited to choosing among the original 12?
If the internal sublevels are only relevant for factory programming or PID, it doesn't change much.
If they're available for programming for the user, so you could set 0.01 even if the lowest listed L2 is 0.12, then it solves everything.
My understanding is that those 2048 sublevels are not available for end user programming, only for factory programming, so we are only able to program the originally included 12 levels, but now, or course, we can put them in any order we want in the UI.
I tend to feel that the very stable and extremely efficient low light levels, available for years on previous models, are kind of a ZL hallmark, and I'd like to see them continue that tradition. In fact, that, to me, would be what could make this into a nearly perfect light, being able to rock & sock it with 2300 lumens, but also have the ability to use super low moonlight levels as well, with a good selection of useful in between levels to boot.
The guys in the SC64c thread were able to persuade ZL to change their planned low for that light from .12 back down to .05, so I see no reason we can't do the same thing with the SC600w IV Plus. Contact ZL and let them know your thoughts.
