Re: Do you prefer Low/Mid/High or High/Mid/Low?
From the small amount of flashlights I've tried so far, I am preferring my Eagletac T25C2's UI the most. Simple twisting with pre-select before turning the light on in the first place. In short order the positions become muscle memory and second nature to interface with. If I want to go low->med->high or high->med->low, all I have to do is twist the head accordingly before I turn the light on. Simple.
Superfluous blinky modes are available in abundance, but well hidden in the UI outside of regular use. There is no getting to them unless you purposefully do so. If desired, you can toggle the option for double click instant access to Strobe 1 on or off, or even program it into a tactical operating mode.
Great UI.
The only caveat I find with it is the way you access the lowest (4th) mode, and that the lowest mode could stand to be lower than it is, but it's not a deal breaker to me.
I much prefer the Eagletac's UI over the other lights I've used so far, which the others cover some of the common types of UI/mode switching available in lights. (Ultrafire WF-502B, Convoy S?, Thrunite TN12 2014, and a Niteye Eye10) After using the T25C2, I'm thinking my next light will be another Eagletac; if not an Eagletac, a requirement would definitely be something that is very very similar to the Eagletacs UI.
