DBSAR, if you want you could likely just copy and paste this to the last list update I provided and update the OP at your convenience, or I can send you a full update some time in the future. I plan to periodically show recent additions in this sort of format from now on. I will still try to welcome new members who post here in the interest thread first (I am sure I have missed some, sorry bout that and a belated welcome to BLF to those I missed, the second round is on me also :beer: :beer: )

The latest list can be found in the OP always (thanks DBSAR) and is posted here for conveniece also:

I don’t see my name on the list :expressionless: (*BLF LT1 Lantern Project) (updated Nov,17,2020) - #2763 by Lothar)

Thanks for pointing that out. Surprised I don’t get fired from this job. . . :person_facepalming:

I added you for 4 Lothar, split the difference. I also added Gregor who I missed in the post just after yours.
I went through the last couple pages and think I got everyone, but it doesn’t hurt for you to check like Lothar did. :+1:

Please add me to the list for 1. Thanks.

1029 WES-7

Done deal :slight_smile: much easier to add the new interest list names in small lots like that. ( Updated the OP to #1029

I will keep doing it that way then, as it is also much easier for me. :beer:

sounds good.

Here below shows the shortened version of the lantern, based from Lexel’s modified drawing, with added knurling to the mid section. ( the battery tube can be the same exact one used for the Sofirn Q8 if that saves cost/price per unit, and eliminate the four flat spots ( like the Sofirn Q8) as the flat sections is not needed.

The flats section look good to me it can reduce some weight and also have the logo on it if the mid section is knurling.

eeeeeeeeeeeeeeeeerm nope…. This is not the lantern you are looking for! (say is with a hint of jedi)

if it don’t add cost per unit, then we can still have them like the original Q8 has. The logo will probably be etched around the head or just below the mid section knurling.

Current design Specifications for the BLF LT1 Lantern will be close to these below:


- uses up to four button-top 18650 LiIon cells (in parallel configuration) Driver based from Lexel, Firmware from Toykeeper (LT1-Anduril)

  • 20% lens frosting (or frosted internal sleeve) for smoother light, but not reduce the output no lower than 5% of bare LEDs.

- Up-coming available accessory kit will include:

I am already testing & refining newly designed accessories with the V2 Prototype now, that will be a good addition for the production model. :slight_smile:
