Like most other people, I’m definitely interested in it and am curious to see how it’ll turn out.

If this thread is going to morph into an official group buy interest thread then, please, let me go ahead and put my name down. I’m very much looking forward to seeing your design for this. Thumbs Up

While we’re not taking names yet for a GB list, it is to see if there is interest in a micro-LT1 for those wanting similar features, quality, and purpose design in a much smaller lantern for backpacking, canoeing, kayak camping, or any need where space is limited and size & weight are critical. While it will have less output and less run times than the full size LT1, it will still be far better than any other mini/micro lantern of the size range available on the market.

Would be nice as a work light for small spaces as well. Attach to the underside of the car hood to illuminate the engine bay. Stand it in a corner in the under-sink cabinet while you work on the plumbing. Or even hang it in the closet that doesn’t have a light already, when you’re looking for something to wear and it’s dark. Also great for night time trips to the toilet or to get a snack from the kitchen without turning on bright house lights.

DavidEF, I like your thinking. A high powered magnet at the base might be nice for those vehicle and plumbing repairs. Thumbs Up

If we’re gauging interest, count me in as well. Make sure to update us when a GB list starts!

Interested in a few of these. I think a micro is supposed to be 14500 though. Mini is 18650/21700

No-no. No 14500 powered things. I have a few 14500 powered “regular” flashlights and while I like the physical size, I do like the limited capacity of that size cell. I guess we all have features that are most inportant to ourselves.

Myself, I would want nothing less than an 18650. Someone mentioned a little ways back that they would like an 18650 light as they backpack and would swap a cell between this new compact lantern and their headlight. I can see the advantage to that, as much as I also like the idea of using a 21700 cell for the new compact lantern.

I am not certain I would buy either an 18650 or a 21700 powered small lantern though. That’s my practical side showing through and overpowering my “Wow! Cool! I love that and want one” not so practical side. I must admit to also thinking about what I might cobble together myself. Facepalm

As DSBAR said here we’re not yet taking names for an interest list. That will be done if and when we proceed with the Micro-LT.

I would go for 21700 battery form all the way, the best ratio of physical size vs mAh these days.

Interested in however this turns out!

I really like the form factor of the zanflare T1 (similar to the Femix Cl25R, but I don’t have one).

There was a debate as to whether the mounting of the LEDs in the T1 resulted in excessive heating of the 18650 cell.

I’d be interested to see if the LEDs could be mounted on the underside of the top- in the same way as the LT1.

I was just joking about the name because of the BLF GT. I wasn’t saying we should do this version in 14500. I was saying that this version (21700/18650) should be called the LT1 Mini. I have a habit of not making my points clear. Sorry about that.

A micro version (should it ever come out) could be AA/14500 and since the focus isn’t on output, Eneloop Pros would be the ideal battery.

I think that I mentioned it elsewhere too, an important feature for a lantern for me, more so than with flashlights, is that it looks attractive. Can we do that?

It so happens that I tend to stare in lanterns during use while camping, I did that with my ancient Feuerhand kerosine lantern and found that thing always a pretty and highly satisfying sight. A led flashlight with diffuser that I used later, however practical, never did anything to me and I think that is a miss. Personally I find the LT1 too plain looking, but is already better to look at than a flashlight with diffuser.

So the request is to pay some attention to a nice looking design. It is highly a matter of taste what exactly looks good, but just looking a bit beyond plain functionality will already help.

Very interested, not found anything that works as well to replace either my Solarforce LT-1 or T4 lantern heads yet apart from DBSAR’s LT1, a smaller version would be very welcome and very useful.

Interested. Would also be nice if the battery tube is the same and interchangeable with any of the popular and cheap 21700 or 26650 lights.

This light gave me idea. It has 2 side lights. What if that was extended all around the head? What if we made it LT1-style, with emitters at the top?
Maybe we could make LT-1 style optics around the driver space? Instead of a long screw holding the head make a short tube. Driver compartment tube. LEDs are still at the top. Use not 8 high-power but many mid-power LEDs to counter the fact that they’l be placed very close to the cover.
In front add a regular optics and LED, so it’s not just a lantern but a flashlight as well.
Tube gives little space for the driver…unless you make a flex PCB (not very expensive now) and fold it inside.

I have one like that atm, its very finicky, flickers a lot, and has some design issues. (added to the radiation-blue tint and built in charger that charged a cell to 4.32 volts.

I would vote for a head with a reflector + a ring of (mid power) leds around it.
