Mine has that fried egg look using those
It irritated me that the tube from the battery is not symmetrical in relation to the head. I decided to change it. I honed the edge of the tube to achieve the right level. Electric contact has improved by the way. This is what Q8 looked like before the amendment:
And so:
Now the symmetry from the beginning to the end is perfectly preserved.

The improvement is striking. Now I'll have to fix mine too. Thank you for sharing.
/\\ . Nicely done. :+1:
So how much material from the tube did you remove? I like it and might do the same 
I wouldn’t file the tube, I’d rather use copper wire and adjust its thickness. Hammering thinner, use a file, etc.
When the tube gets off over time you can replace the wire with a new one.
I collected about 0.5mm so not much.
For me it is such a makeshift. I prefer more lasting solutions 
Folks, got my Q8 today and top battery tube o-ring was caught in the threads when they screwed a light head onto the tube and it ruined the o-ring it is cut now. Contacted Thorfire and they told me to go pack sand, they do not stock or sell those o-rings. Banggood asked me canned question for the picture when I already included pciture of the issue, they simply do not even review. With that what o-ring do I need to buy and from where? Much appreciate the help. The price we pay to buy "budget" from budget sources
Now I don’t have a Q8.
I think the one on the lens of C8 works.
Tonight I’m checking it out.
Checked!
It is the same as the C8 lens.

Thank you! Huge help to Q8 owners. I will get 10 of them and it will be more than enough for the life of this light.
Ordered! Thanks!
Thanks for checking - Ordered
I need to talk to the developers/designers of the Q8 driver, (possibly for the BLF lantern project) as i don’t remember who was the programer & designer of the driver for the Q8. ( updates posted here: >> *BLF LT1 Lantern Project) (updated Nov,17,2020)
DEL did the driver.
He has drivers on Oshpark
Tom E. did the firmware. But he is now rarely on BLF.
…in the meantime ToyKeeper knows the Q8 firmware very well and can do extra magic to it!
Ish. I haven’t actually done much to the Q8 firmware… instead I kind of rewrote everything from scratch using totally different abstractions. It has a similar basic UI, but the code bears almost no resemblance.
Either way your candle & sunset modes would at home in the lantern!
In any case, I already have everything except the driver-specific details working. All that is left in terms of firmware is to add support for the lantern’s particular hardware, which isn’t yet determined. But if anyone wants to try it on a Q8, there’s a compiled version available.
BTW, to configure the illuminated button’s behavior in that build…
- First, go to lockout mode (4 clicks from off).
- Click 3 times to change button brightness in lockout mode (off, low, high).
- Or, do the same but hold the third press (click, click, hold) to change button brightness for the regular “off” mode. Let go of the button when the brightness gets where you want it.
