I believe seeing your living room before. I guess once you did a review on YouTube with the Xeno e03, a Fenix light and another AA light! Is that correct?
Thanks, yes, it's never been done, it's mathmetically impossible to fit 3x123 in mag tube passing the top thread section.
I did DIY tri-bore & bored open the O-ring groove, thank god it didn't bore open the thread, another 0.2mm it'd have bored through the thread & the project would have fell apart.
The youTube isn't me, never posted a video before.
Not parallel, parallel wiring is risky. Vf difference will cause some led to get more current, eventually the higher amp led might burn out, then the rest gets too much current. learned my lessen on a triple XPG parallel a while ago. Wiring in series is always better than parallel whenever possible, all 3 leds always get the same current.
