I like everything about Olight S Minis, except they are Low CRI, and not N219b compatible (they use XM-L2 architecture). There IS One High CRI version, the Olight S1 Mini High CRI. But the LED is XP-G3, with very green tint, and modding that model is difficult (the bezel is sunk into the body and removal is destructive).
for small 16340 with High CRI off the shelf, the Klarus Mi1c is a winner.
FWIW, that particular light does Not use an Aspheric lens, it has a reflector, a wide spill, and a throwy hotspot.
The Klarus UI is not my favorite, requires a long press to turn off.
But the light is small, very pocketable, and it includes a USB rechargeable battery. No charger required, just a phone cord.
There are also copper and titanium versions,
they are Low CRI, but not difficult to modify to N219b, CRX could do it easily.
