These are only resistors to limit current to the LEDs in the flashlight.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

correct.
the leds are in parallel with 1 resistor in series with the group to limit current.
the vf is close enough that current hogging is a non issue.
