There are different address auditory for mini EDC FL.
For one of them, mEDC used for typicall fast works, where no high light output or runtaim required. So, they are looking for builtin flat FL, or AAA.
For other, size have matter, but runtime and amount of light - too.
As for me, i think would be nice reincarnation of old Trustfire Z1 with XTAR quality and features.
At first, it is very compact, not as AAA but close.
16340 is not bad, may be 18350 with close size if possible.
Good feature -* i can dismount reflector and receive 100% floody light against true thrower with it.* Yo should only provide additional glass inside to protect led in this case
I can use it with head strips as headlamp. And even with any lent.
At stock there are no magnet inside, but i add one.
The main problem is old XP-E inside and bad driver with hi-lo mode.
So such FL would be nice with new led 4000-5000k HiCri and CC regulated driver. Of corse with LVP and overtermal protection
UI:
Anduril, but if not - something like manker. One mode for click&hold which could be adjusted with memory (from 0.1 lumen up to high), and lo(30)-mid(90)-hi(200) in main line, turbo(400-600) for double click as example.
