MF04S clicking sound on stobe... have video

Anyone else have this clicking sound in strobe on your MF04S? You may need to turn up the volume to hear it clearly. I uploaded the video to flicker here ---> https://flic.kr/p/2ik4644 It's kind of annoying but so far I never had a need to use strobe mode.

Not sure if it’s as loud but this happens on my MF01S. Can’t hear it on the FT03S even with my ear right next to it.

Odd, I don’t recall noticing a sound like that. I later swapped for Lexel driver running Anduril, 10/10 would recommend. It’s like owning an entirely new flashlight now that I don’t have to hold the button to turn it off.

I just tried my mf01s and you're right, it does it too, but I have to put my ear right on the light to hear it whereas with my mf04s it is quite loud, but maybe it's just normal because of the larger head amplifying the sound. Mine sounds like a ufo landing in those 1960 type movies.

With the Lexel driver, does the side button still light up and does it still turn red if the batteries are depleted?
