Love the idea and truly appreciate all the hard work that went into the project.
Wish I was 1/10 as handy or useful…
Darn it, I think me wants one, why? just because…how much?

Perhaps the battery tube, but probably the rest will be different. Just what kind of “compatible” are you looking for? I think since there’s now such a thing as extension tubes for the Sofirn Q8, it would be nice if the tube of this light were made compatible with those. The “stock” Sofirn Q8 battery tube won’t work to be extended. So it must be replaced in order to add the extension. Therefore, the “extension set” includes two tubes and two battery holders. If this lantern’s battery tube were to be already made like the “replacement” tube, then just a single extension tube and battery holder would need to be bought for it if someone wanted to extend it.

AguassissiM, no firm price yet, likely around $40. I think I may have provided lower estimates in earlier posts but the reality my SWAG is based on something I read in this thread a long time ago. Sofirn has not provided any sort of price estimate at this time.

Doctawho, not exactly sure what sort of compatibility you are looking for, but the design is leveraged heavily off the Q8. Put you on the interest list, it is not a committment to buy, just trying to gauge roughly how many lights will sell out the get go for Sofirn.

That would be great to test for the BLF lantern project. (as were discovering the Samsung 351 series is harder to order apparently that the manufacturer was telling us, and need to find a good replacement LED type that has good efficiency & tints for lantern use. (send me a DM for more info)

Great because this means that the nichia optisolis can be considered as a candidate…a true ultimate lantern should use those LEDs or equivalent.

For the emitters, you might want to consider the Oslon Square 2700k 96CRI. The tint is absolutely gorgeous for the color temperature. No yellow/green. The one sold on Ebay is a slightly rosy 6U tint bin and a high flux bin for the CCT and CRI.

Additionally, E21A 9080 tint mixing would be a really good option.

We may have to consider that option, as we discovered the Samsung 351 series LED are hard to order by the manufacturer. If Olson makes them in both 2700K & 5000K with the same foot print as the 219, XP-L, etc. that would be perfect as long as they are more efficient Lumens-per-watt than the 219 series.

FYI, Digikey does have the LH351D in 2700K and 5000K.

But they can only be ordered in quarter bins (can’t choose between above or below BBL), as far as I know.

Is there anything that an enterprising community member can do to help this project along?

Not that I’m aware of. At the moment, I think we’re mostly waiting on Barry&co to build and test Lexel’s driver design. I also have some firmware updates I could make, but I’ve been trying to finish other stuff first.

Curious …. just how long has “the ball” been in Barry&co court? An update(even if it is not about the lantern) telling us what is going on would be nice. Anything indicating the project is actually moving forward.

I think Barry got the files just a few days ago. I’m not sure how long it takes to print the circuit boards and get all the components, but it’s probably faster than ordering from Oshpark.

I must admit I haven’t followed the project very closely beyond what is needed for firmware. I’ve been kind of enjoying not being in charge. I can at least say the project is moving, though. There were some unexpected delays from several hardware updates, but it sounds like it’ll probably go faster now.

Add me to the interest list as well. Been watching this for awhile from afar. I need a decent LED lantern, I’ve convinced myself.

My rules for flashlights:
1) Always have an option for Neutral, Warm, HiCRI
2) Just say "NO!" to proprietary cells and battery packs
3) Have a KISS interface: no scrolling through blinky modes

(I'm also PhantomPhoton on CPF; reddit.com/r/flashlights; LPF)

Waiting to hear for progress from Barry really. Its going slower than i been hoping, but i don’‘t have the BLF project experience or knowledge that the organizers of the GT or Q8 had. Originally we had TheMiller who has much more experience in projects like this helping us, but he went missing in action over a year ago, and i just don’t have his ability or experience to push this project through faster. We have a great team of people working on the driver & helping with the list and other things including ToyKeeper, Lexel, SBslider, BlueSword, Bmengineer, and with Barry of Sofirn on the team, but my hands are tied on to know exactly of the things needed to get it rolling smoother. All i know of right now is waiting for the driver to be developed at the factory and waiting for updates from Barry, and try to provide him with anything he needs to the best of my abilities & what spare time i have.

I miss TheMiller too. If without him, the Q8 project could take longer. Several days ago, engineer arranged a prototype of board but still wait for it……At the same time, contacting Samsung led supplier for the needed leds, also waiting……. I’m not sure if a prototype of lantern can be made before Chinese New Year arrives.

Thank you Barry for the updates Smile much appreciated. we will provide all the information you need to help make the BLF lantern a reality.

Barry from the factory have provided a photo of the new LT1 BLF lantern driver board prototype ready for the firmware testing for the lantern! (components & brass positive contact ring to be added)

I hope that is just a quick and dirty prototype finish i.e. the HASL solder instead of e.g. ENIG plating for production.

Presumably it will be fitted with the Q8 brass contact ring ?

Looking forward to seeing it assembled and tested. Nice to see progress, and that you are continuing to make this happen, despite any personal worries.

Good luck.
