Thanks for the list of options. I've been taking some time to create a list of lights with their UI's. I've tried my best at understanding the different UI's, and I may be wrong on how they work. Some of the UI's are just confusing, especially when you have more than one flashlight with differing UI.
Here's the list so far:
Surefire U2 Ultra
Good
Yes, this is the UI I'm looking for.
Momentary on.
Constant on.
Brightness selected by twisting bezel.
Bad
Too Expensive.
Size/form factor makes it not a pocket EDC.
Eagletac P10c
Good
Momentary on.
Constant on.
Brightness selected by twisting bezel.
Can tailstand.
Two brightness levels: High/Low (220/60).
Wish
Wish for something lower than 220. I don't want to burn through the battery in .7 hour.
Fenix L1Tv2
Good
Momentary on.
Constant on.
Brightness selected by twisting bezel.
Output levels: high/low (96/16).
Seems similar to Eagletac except for output, runtime, battery, tailstand.
Wish
Wish for higher lumens (130 would be nice).
Wish for longer runtime.
Maybe a CR123A?
Tailstand
Surefire E1B
Good
Momentary high via single press.
Momentary low via double press.
Constant high via full click.
Constant low via double click.
Bad
Price
Can find similar lights that are brighter (80/5).
Fenix Forward Clicky
Get momentary on/off, but lose constant on/off?
How do I select the desired output? Same with regular clicky?
Bezel twist for output would be ideal, but I may be okay with clicky.
Olight T10
Good
Change brightness levels via bezel.
Bad
No momentary.
NiteCore Extreme
NiteCore Defender Infinity
Good
Full depress = Constant on/off
Half depress = momentary
Bad
Output selected by loosening bezel, waiting for desired output, then tighten bezel.
Spartanian
Bad
UI looked confusing to me.
Seems big.
