I been working on designing & testing a shade/globe design that does seem to work really good with a single LED that fires up in a small diameter shade, to allow as much light to shine downwards and 360 degrees without the up-firing eye-glare & lack of down light syndrome found in most up-firing lanterns, also this design has nearly no artifacts like the LT1.
The idea behind the LT1-Micro is to build a a small, slim lantern based with some of the features of the LT1, but simpler and lower costing, and small enough to pocket or sleeve in a backpack for backpacking, mountaineering, and camping trips where space & weight is a concern, but still have a lantern that can recharge off-grid via solar charger or power bank when on trips, have great run-times, great modes, (same as the Andruil in the LT1 full size lantern, a nice warm single-tint high CRI light, but with a dual ability (table lantern & hanging area light bulb)
I have built and modded many small, pocket sized lanterns for quite awhile, (video of those coming soon) but to have a consumer marketable micro-LT1 (and later possibly a mine mid-sized LT1) for those wanting a tiny lantern version of the BLF LT1 for backpacking, canoeing, kayaking, mountaineering, and any purpose a small, pocket sized version would be a benefit. While the current LT1 beats any other full size (and bigger) consumer lanterns on the market, there is still a lack of a small pint-sized lantern on the mareket too, and this LT1-Micro version can fill that gap. :sunglasses:
I have used a variant of this camp lantern for about 12 years now.
It has high function, is utterly dependable, easy to use, and goes for about a week the way I use it, on a set of 4 AA batteries. What it lacks is rechargeability, and use of lithiums. I’ve not tried sinking it in a pan of water. Notwithstanding, I would buy a BLF version just cuz, though being metal (?), it would probably weigh twice as much.
Looking forward to the video. :+1:
Also thinking plastic should be considered due weight considerations, and also cost. Assuming reasonable durability, but the lighter it is the less force acting on it to cause damage.
Sounds interesting. Is there an interest list yet? 
I’m 4054 on the group buy list…when will I get my code?
I’ll absolutely pick up 2-3 if it gets made.
Not stupid at all.
Review: Solarforce Lantern Converter
I never got around to grabbing a Solarforce LT-1 but I do have the similar one from the T4 kit.
I'm very interested...
A BLF LT1-Micro sounds great!
By the way, I would much prefer a 21700 host to a 26650 host.
I’m interested. Also agree that 21700 is the way to go
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.
That is gorgeous.
Im interested in more compact 21700 version too. LT1 is too heavy/bulky for me to carry in backpack.
I’m interested in 2…especially 21700 format.
WOW!
Interested!
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.
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.
