I’m interested. Also agree that 21700 is the way to go

BLF LT1-Micro sounds great!


By the way, I would much prefer a 21700 host to a 26650 host.

Agreed with you on the 21700 size. No need for the extra diameter or weight in this case.

Maybe I should make a left turn and throw something together to test some concepts, and enter it in the Old-lumens hand made light contest at the same time.

Design ideas could be taken from the Nitecore LA10 CRI and upscale it to take 21700, onboard charging and Andruil.

Im interested in more compact 21700 version too. LT1 is too heavy/bulky for me to carry in backpack.

I’m interested. Something small with a 21700, 4000k and high CRI would be great.

Also interessed but more in 26650 format. Should give a more robust stand due to better diameter / height ratio.

Stability when standing the lantern on the end is important. However, I don’t believe that is alone is a good enough reason to choose a 26650 cell over a 21700. Correct me if I am wrong but it seems to me that 21700 size cells offer greater capacities than any 26650 cells.

Maybe it is more important to use a 21700 cell for greater capacities and then just make the standing end of the lantern enlarged?

Thoughts on that???

I agree on that the 21700 is a better (more modern cell size with 5000mAh capacity) choice, and the plan to have the LT1M with a magnetic base, will be easy to have a flat base stand that sticks to it included. (already working on it. Big Smile

With 21700 we could achieve bit narrower profile. The final shape is very important at least for me, I would greatly like something similar to the recent Nitecore Campbank lantern, which is more or less flat and can be easily worn even in pocket.

The Nitefox UW360 has that, a flat disc that lets the critter stick to it to stand upright on nonmagnetic surfaces.

Very interested, I also think 21700 would be preferable. In regards weight what is the current target if there is one? The reason i ask is that when wild camping weight is a key issue, i dont get to just take things out a car and walk 5 feet in a campsite.
Thank you DBSAR for all of your lantern work recently im looking forward to this one.

Actually, Shockli’s 5500mAh 26650 cell delivers fantastic currents and also tends to test at or above capacity rating. Someone else sells it too, I forget who. To me it’s the best compromise cell, like a 30E. A 40T will get you higher drains but to me I’ll take the 1.7 extra amp hours.

This light will not require a high drain cell.

Exactly. Are there 21700s over 5000mAh like there are for 26650?

26650 is to heavy for backpacking. Even 18650 is considered to heavy for some of us. But pared with a 18650 headlight I might consider taking a lantern that runs on 18650 as I only need to take one type cell with me. There’s no need for long runtimes or high output an 18650 is more than adequate if you really want to design it with backpackers in mind. Also size matters while backpacking, make it as small as possible. No need for usb charging (how the hell you gonna charge it in the forest?) but could be useful.

I smell another 10,000 post thread in progress (with less than 20 posts worth reading) Silly

Count me in!

Might as well also start thinking about the LT1-Maxi with 100 emitters and 20 × 18650 capacity. Thumbs Up

And please maintain your health, that last one took its toll!

Interested in this. If a suitable host can be found, I will gladly contribute a few dollars to get one sent to DBSAR for prototyping.

Interested. There are too few details to tell for sure and I’d definitely like to know more.
