I have the BLF A6 and the AstroLux S1, each with the 18350 tube. I’ve also ordered the Convoy S2+ 18350. And I plan to order the red and blue AstroLux S1 18350. I want to use these protected KeepPower 18350, but I’ve seen a couple of people say that protected 18350s won’t fit in these flashlights.
Can anyone definitively confirm that protected 18350s will NOT fit in these lights? Is my only alternative to get an unprotected 18350, or to use a protected 16340?
