I did that twice (times two B42's). I turned off force setting (really memory on), which was big for me, and turned on momentary. Would not mind a lower low, but based on the Novatacs, I figure I would be likely to find a level where they start to flicker, and then I would want it back up, so, nah. I figure with a little higher low, I can spend more time on that level, and save more battery. It's by no means blinding in the middle of the night, but is way more than the minimum. I believe default low (D) was 0.33 lumens before I modded it, so now probably around 3/4 of a lumen. Minimum stock was 0.08 I think, so that would mean they are on level 5 now. Those bottom few levels had a tendancy to flicker, and I see it routinely on my Novatacs when set real low. Sometimes I can just give it a quick burst of momentary max with a press-hold, and it stops, but then sometimes it comes back. These are the sort of things Henry flushed from the circuit design in the new ones. Unfortunately, along the way the uber-long low run time got lost too. I've said it before, my favorite UI is the 120P.
