I've been reading up on this setup, and have seen references to noticeable PWM on the lower modes and possible preflash. Is that still true, or has that been programmed out? Second, does anyone know the approximate output at each of the four levels as it comes from Don? I'm looking for a flashlight that does it all well, not necessarily specific to one task. Is this combination ideal for that? Or is there another suggested tried and true setup? Thanks!
