This thread is killing me!!! You're killing me SMALLS!
@md17 Does your light have the Malkoff hi-low ring in the head? If so, is it tight and clean?
I will say, I had two 18500's in my Olight M30 at one point. I dropped it on the concrete and the protection circuit slammed shut on one of the batts and stopped working. There was no flickering. That being said, I appreciate you sharing all the detail about these cells! Sometimes some sets of hardware yields unpredictable results. You got me paranoid now because my bedside bored Surefire M3 currently has two 18500's behind an XHP50.2 on a 1.2A driver.
