My q8 is stock and on turbo it will get scortching hot. Maybe not hot enough to damage the components. Maybe yours gets warm because you havnt disabled the thermal regulation
@patmurris, as mentioned before, it is going to be a BLF Q8 V1.5.
They are going to put NarsilM V1.2, just change the LED to XPL HIs, and a bigger extended tube.
Why are you worried about it? It is just going to be the bigger brother of the Q8, not a different one. It would be hard if they would miss the target, as they have every part available already.
Even then, it would just be how a modder would modify the Q8: swapping the XPLs for XPL HIs, flash NarsilM V1.2 for better thermal regulation and features, and bypass the springs. The only thing that a modder couldn’t easily do on their own is make a bigger battery tube, but this is why we have this new Q8 V1.5.
If they only swapped leds and upgraded the firmware i would agree, but the long tube which will require two battery carriers seems to me a sharp departure from the original SRK/soda can concept, introducing complexity to a simple design. It’s a matter of POV of course.
That said, i’m not sold at all about this direction. All this just to extend the already very decent run time seems to miss the opportunity to move further and address 6V and 12V emitters. I’d rather have the same short tube form factor with XHP50/70s. That would be a big brother - that can keep you warm for sure!
1. Yes, the tube will be sold separately, but need to change the both two tubes. Springs better too. Copper alloy.
2. Checked with our factory XHP50.2 NW 80CRI will be considered in next update and XPL-HI will be used this time, for enthusiasts who want better color tint and long range. XHP50.2 will only require modification of battery carrier to work, so XPL-HI releases, flashlights enthusiasts will only modify carriers and driver to work to get XHP50.2 working if not waiting for update.
I’d hardly call my Q8 scorching after a minute of turbo with spring bypasses and Luxeon Vs. Stock it never got hot at all even after several minutes just warm to the touch and I clocked mine in around 4500. All temp regulation off. After bypasses it gets warm a lot faster, but still nothin like the Emisar D4.
I wanted to get carryers for modding from the beginning, but the team has declined becaus it should be SRK-Style.
Now, that would be great.
And we will see, how the carryers could be modified. There seems to be only the center bar, which could be used to make Bat+ contact from the end to the top. The other bars are used for battery- or ground.
So with different carryer PCBs it should be possible to make a 2S2P or 4S1P variant.
Ok, now we have a MCPCB for XHP50, we’ll hopefully soon have the new battery tubes, now I need an affordable source for well binned XHP50 or XHP50.2 in neutral or maybe warm white. Are XHP50.2 suitable at all for a FET driver? I guess I have read somewhere they have a lower forward voltage than XHP50.
This is a good question but not because of the voltage. I have a XHP50.2 running fine without driver on 2 high drain 18650 batteries so at least some XHP50.2 leds can handle that. But I had one dying at much lower current in a light with 3A boost driver from KD. Something with a sensitivity for unseen voltage spikes?, I don’t know. At least the Q8 will not use a boost driver but a simple direct FET driver, could be advantageous for the XHP50.2
