I believe that there is already a thread for this tube mentioned by BlueSwordM.
I made the same mistake and propogated it. Those that would like to show interest in the extension tube should go to this thread and post their interest.
This lantern is based on the Sofirn Q8 design, at least the body and head began there. Obviously there are some significant changes, but the tube extension tube for the Q8 should be compatible with the lantern.

Having the option for a battery expansion tube sounds good, but maybe we should also consider the option to make (replacement) battery tubes for larger size batteries like 26650s or 21700s. They would also enhance the runtime significantly but are smaller and lighter than a whole second tube/battery carrier and would maybe also give the lantern a better stand than the standart (or even the longer) version.
And @The Miller: I donāt think that a crank or small solar panel on top would make any sense on a lantern like this. With a battery capacity that big it would take hours of cranking or weeks in the sun to noticeably charge the batteries. A large external (usb) solar panel makes much more sense.

I think we are years past that point. You are talking about trying to spool up a whole new production line. The benefit of this project is it uses an existing platform. Besides, once you are in 4x 18650 territory running as low a current as this will run, the differences really arenāt worth it. Youāre going to be hard pressed to ever run out the batteries as it is. Something 4x 26650 would be super annoying to lug around as well.

Iām on the list for 3 lanterns (#s 219, 220, 212).
Please put me on the list for 3 extension tubes as well.
Thank you!!

That thread is targeted for the Q8 which I assume is being monitored and the interest list maintained by the OP (BlueSwordM). Iām willing to maintain an extension tube list for the lantern (since I would get one myself) but as I donāt have any interest in one for the Q8 I donāt look at that thread, and have no plans too.
I will add those who express an interest in an extension tube in this thread to my database but anyone who did so in BlueSwordMās thread with the expectation that it will be for the lantern will have to do so in this thread. Is everyone 100% sure that the extensions work for both the Q8 and lantern?

Thatās where the problem comes in:
Your idea is great, but Iām afraid the compatibility is an issue, since the threads are slightly different between BLF Q8 and Sofirn Q8, even new batch and old batch are different.
Furthermore, the BLF lantern is still being designed, I donāt know what a design it will be.
That last line is what is problematic.
Hereās the link to my thread about the Extended Tube Set:
So, we all love the BLF Q8 right?
WE love modifying it, making it brighter, more customized, better, and cetera.
First off, we have Sofirn which now sells the BLF Q8 MCPCB, the reflector, and the switch for anybody who wants to modify their light and easily swap parts, or make something completely, like a lantern

Isnāt the current extension tube interest list for the Q8 and not the lantern? If weāre talking about tracking LANTERN extension tubes itās simple enough for me to capture it in the same Oracle table Iām using for the lantern. A web app would be ideal but my home system isnāt set up for that. However a thread that is only used for expressing interest in one would be simple enough for me to monitor and then to insert the user data into my table.
A separate thread would be the way to go in my opinion.
If Sofirn builds the lantern with the head body & tail cap threads the same as their Q8, then the Q8 extension tubes should work just fine without having to design & build a new one. Just order the Sofirn Q8 extension tubes.

Letās go with that approach. Anyone interested in an extension tube can post their interest in the other thread which is maintained by BlueSwordM (assuming heās the one currently doing so).

You can see all your past posts by clicking on your name. Same for any member. Here is your first post. It was a different Group Buy, but it wasnāt long before you posted in this one.
Hello, this group buy has piqued my interest, but I would rather not commit until I see a price- Is it possible for this to be sent to me in some way? Maybe I missed it?
Thank you!

!!! Important Note !!!
Anyone who has expressed an interest in a lantern should verify that their BLF user name is correct in the Interest list by user names link. When the lanterns are ready for purchase the pmās will be automatically generated based upon the user name in that file so if your name is incorrect then you wonāt be getting a pm 
This is a one time only check so if your name is correct now then it will be correct going forward. In other words you only need to check once. Note that embedded spaces are valid characters so for example a name having one embedded space is not the same as a name having 2 embedded spaces.
Different letter cases in the user name doesnāt matter. Eg. Userxxx is the same as uSERXXX for the purposes of the pmās.
If a name needs to be corrected send me a pm and donāt just post it in this thread because it could very well be missed.
DO NOT send me a pm saying that your name is fine.
Thanks

an extended tube would be good , Iām in for one.
So wait, Iāve heard a few different things now, kind of conflicting, do we have an official way to express interest in extended tubes that doesnāt involve filling this thread with noise?
Not trying to be rude, just an honest question.

Thatās interesting. I can access it using Chrome, Firefox, and Edge. Do you have java scripts turned off? It has to be enabled to display the file in the link.
