Lumintop GT4

+1 & Amen… :+1:

Very nice…

Interested!

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.

;)

How 'bout some nice auxiliary LEDs? Would that be feasible like in the D4S or E07?

Lux-Perpetua cool idea they should do it, there is place for it :smiley:

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:

That BD01 indicator is nice!

What about having more length on the tube thread, so users can grind down a quarter or a half turn by themselves?

The battery tube can be indexed to any position you want on the GT and GT70, the anchor point on the head was the main complaint.

Ah thanks, now I remember.

I’m in for one.

Yes, this is what I do with my battery tubes. Like KB said the head sling point is the one that can’t be indexed.

Interesting idea, although it would be a lot more complicated then it sounds to actually do it.

Plus Narsil does not support separate LED’s, so the best it would do is be a copy of the side switch LED in function.

I can ask about it though but I am guessing it would increase the price which is already going to be a possible issue.

Hhhmm. Think'n if we got a spare pin on this driver, I could add support for a 2nd AUX LED(s), but may be a bit involved.

Forget how the buck driver support works - if 2 pins, then maybe can't work.

5 available I/O pins:

  • switch
  • AUX LED
  • 2S required voltage divider input
  • 1 or 2 output channels (FET+1 is 2 pins)

Thank you Texas_Ace! :THUMBS-UP:

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.

It uses an FET + 1 setup, much like the Q8 driver when it comes to pinout. The actual design has been beefed up a lot though.

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.
