I like the Reylight Ti Lan v3. It’s not the smallest 14500 light there is but the Nichia 219c on it looks nice to me. There’s enough room in the body to take protected 14500’s.
Links to Rey’s shop:
Ti version starts at $68, depending on style and LED.
Cu version on sale starting at $49, depending on style and LED.
The smallest 14500 light I have and like is the Manker E11
I did have issues with it turning on by itself in pocket or clipped to belt. So I did manual lockout. Also I think it’s cool white only and it won’t take protected cells.
