Thrunite and Acebeam have the best UI in my opinion. While it has several output levels it's still very simple to use and can be used as a single mode or multimode light.
Both these brands offer models who can provide around 4000lm steady for around an hour or more but they are large and heavy. Unfortunately steady 4000lm and compact is still not a working equation. Hardly not even 2000lm.
Acebeam, like a L30 GEN II.
USB on board
Good beam pattern
..if that light doesn't work for you, nothing will.
