What about two groves for a “clip” at the head and the body?
The clip is a half circle lampshade to enhance light in one direction.
In use you clip it to the top, not needed to the lower part. 
And Sofirn offers the Lampshade Clip for extra costs
Plastics are usually easier to mould - and therefore cheaper - if they are slightly tapered. That way, they eject from the mould more cleanly. A straight up-and-down shape can get stuck in the mould by friction, because it has to slide out instead of just falling away.
When it comes to fracturing, the lantern design has a centre bolt which will hold off any vertical loads. If you apply a heavy load sideways, directly to the polycarbonate, nothing will save it, tapered or not.
As to the rest: ultimately, DBSAR decides. I’m personally quite happy with the way this project seems to be going.
Hi, I think you may have missed my previous post (#2233). I’m also interested in one. Thanks
Looks like this thread has lost a lot of momentum. I hope the project itself is still moving. :question:
Hi piyoman, if you carefully read post 2236 you will find that you are number 937 on the interest list. The list in the OP has not been updated in awhile, (last interest number is 908 on that list) but be assured you are on there.
The master user lists are actually google docs I maintain, and can be viewed by most folks, but for some reason not all. I haven’t figured that one out, that is why I periodically send DBSAR a text version and he updated the OP.

The user name list often as the last few entries not sorted in, so if you don’t find your name in alphabetical order just look at the end of the list.
Don’t we have some LEDS with better R9 and rosier tint @3000-4000K?
Do we have some price estimations?
Two random ideas:
-Would be great if the lantern could be used with 21700 to get close to 20000 mAh. A little sleeve could be used for 18650.
- Foldable legs so the lantern could be more stable on a uneven surface (which happens often in camping)
It has an 1/4” tripod mount, foldable legs would only make it cheaper and more complicated.
Right. I’ll have to buy and carry a tripod.
I’d love if we had even a rough price estimate. Are we talking less than 100, 100, 200, 200+? It will greatly affect how many I buy. If it’s <100, I’m probably in for an additional one or two on top of the one I’ve reserved. (Don’t add me to the list, just making commentary.)
Its still going strong! were just waiting for the engineers as Barry mentioned to me, as they are working on the design. Also still in wait of the driver PCB design.
If there is still enough metal left in the tube its possible, but not sure if the Q8 body design has enough metal to allow the bigger cell size.
a snap on place base may be in the works for added to the accessory-kit that is planned once we get the lantern into production.
that’s agreat news ! :+1:
DBSAR, what are the dimensions of the diffuser cup? For making a more accurate design.
The lens/globe part? ( i can get the measurements for that when i get home.
Yes the lens/globe part.
Kit sounds good I posted here *BLF LT1 Lantern Project) (updated Nov,17,2020) - #2330 by joechina an idea for an reflector, if you want light only in one direction instaed of 360 degree.
I’m interested put me on list please
Dannyboyy added to the interest list at number 952.
*Ok some updates: Barry contacted me earlier and they are in need of a base driver circuit design, and asking about the UI (i’m guessing the firmware for the lantern, which i believe Toykeeper is working on that)
I don’t know who designed the circuit board for the Q8, but we are in need of something for the planned two-channel tint ramping, Their engineers are held up on these components at this time, for them to continue they need some basis for what were looking to achieve for the tint ramp & charging system. Without a board design or someone who can help us with that… the only other option is to revert back to using the Q8 board modded with 4-7135s and no tint ramping or charging feature or USB feature. Any input on this form anyone here woudl be greatly appreciated as it seems were held up without a finalized driver board design to incorporate the tint ramping feature, charging feature, & USB power bank feature.*
