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
We (the Q8 team) had a flashlight made with one very well thought-over led choice for simplicity of the process. We never intended to proceed the Q8 project after that with extra versions, so just waiting for a cool white version to spontaneously happen was not a very favorable approach.
But now that Sofirn is involved that may be different, they tend to listen to what is popular on BLF. So ask them for a cool white version and convince them that it will sell.
I use an even worse setup and it works every time.
I have an induction cooktop and use a super old rusty one of these with knife marks on it. I dont recommend it because when it gets hot and cools off the center has a tendency to “pop” in and out with temp changes.
I spent so much time on this project that I feel like a Q8 Team Member.
Remember back when it was said that once the group buy was over Thorfire would take over and possible rename the light and do whatever they wanted? I was really hoping they would add a CW option. It seemed like a no brainer as the majority of flashlight buyers in the world (excluding BLF and CPF) prefer CW.
At this point in time I have no idea if a CW version would sell. I may be the only person in the world that wants this, but I’m not willing to pay double the price to modify it. I don’t need it that badly. I’ll just wait and see what Sofirn does.
