I’m facing the same issue; very little use for the light for the next 3 or so months. Apart from that and the fact the light seems too nice to carry and get scratched up, everything’s looking good.
Thank you team, mfg, everyone. The FW3A is even cooler than expected - in warm white of course.
Oh, the threads on mine were apparently dirty and loose on arrival causing the symptoms described by many others. Cleaning and reassembly fixed that.
Let me correct you here. The inner tube does not carry any led power. It only carries the very tiny switch signal.
The emitter gets current through the outer tube when the head and tail are somewhat threaded together. This is why you see the leds blink as you are threading them together.
It takes the precise tightening of the tail first, then the head, for the inner tube to make good contact and allow the switch to work.
The only in between state I can think of is the inner tube not making good contact which means the switch won’t work.
Is it possible to know when to order to get the updated firmware? Like a specific date where all FW3A’s shipped have this firmware? Thanks for all of your hard work updating it TK!
meh at least with the 18350 will be a lot easier to have it as a keychain light and when someone needs light boom blind the whole area for a few seconds lol
Thanks for the correction. I understand what you’re saying, but light behavior puzzles me. So I make about a 1~2mm turn of the head while LEDs are powered, which cuts power. I then press the switch and I get a moonlight strobe. Easy to reproduce. So does this mean outer tube contact is still good but switch senses insufficient power because head isn’t fully tightened?
