Can't the flats be set to line up with the button by loosening the battery tube slightly until they line up then tightening the tailcap holding it in place? At least that what someone else recommended long ago and I have did ever since. Of course, that won't help to line up the strap attachment point.
Something like the charging indicator in the Convoy BD01 would be coll too.
They use transparent centering-pieces with path through the MCPCB and shell to a LED on the driver.
You can see it here:
Would there be any downsides if the GT4 came with Andúril instead of NarsilM 1.3, so the AUX-LEDs could be controlled somehow? I assume it's not only about the software but possibly also about more complicated hardware (more channels/pins to control auxiliary functions like with the ROT66 that first came with NarsilM and later on with Andúril?). I doubt that customers interest would be substantial if the AUX-LEDs were hardwired with the side switch only and only light up when it's in standby mode with no chance to deactivate it. Anyway, thanks for asking Lumintop what they think about it.
I have been trying to get Anduril working for a few months actually. I wanted to use it in this light at first but sadly the thermal control is not stable it seems and allows the lights to runaway to 100c+. Since that is instant burn level it rules it out as a possible firmware for a production light until that can be fixed as you can understand.
Besides a few minor things that I think TK has been working on, I really like Anduril and would like to move to it. Although it also just controls the AUX led’s the same as the switch, there is no separate control that I have seen since they use the same pin.
Another issue would be actually mounting the LED’s in those locations, that would be easier then it sounds without an expensive setup under the reflector. Thats why all the Aux LED’s I see now are either under clear TIR optics or in setups that can have them mounted to the same mcpcb as the main LED’s. This is cheap and easy. Trying to mount them at a different height is much harder.
