Mostly run time, but since it will use carriers you could adjust it to run at higher voltages. Swap the mcpcb and you could get some really high outputs.
While the temptation is there to make the Q8 have massive output, don’t do it. Bump it if you must, but the huge gains bring huge heat and makes the light almost unusable. I know, I know, but it is what it is…
Just out of curiosity: Will the long tube of the Sofirn Q8 fit with the BLF Q8? Will those 8 cells in the long tube work in parallel or in series? Thank you!
The v1.5 uses carriers. I guess they can adapt the end to thread on to the regular Q8 head. If they use the same emitters, 3v xpl, then the carriers have to be in parallel. So you have the same voltage, but more run time.
Of course carriers can be modded to give different voltages. If Sofirn made a head that used 4 x 6v xhp70.2 then they would probably make the carriers 6v and they would still be in parallel.
This is probably a topic better discussed on the v1.5 thread.
Maybe Sofirn can give more info on the extended tubes.
I happened to run across this picture by Khas. You can ignore the color differences because that’s not relevant. You can see the smaller and tighter beam of the XPL HI. It’s not a big difference, but you can still see it.
Are you wanting to buy at an Amazon store? I think other Australians prefered the Aliexpress store which you can buy right now. Instructions are in post 1.
