Do you think there’s enough space in the battery compartment to put a small version of the cheat sheet? Perhaps rolled around the batteries?
……

Hmmm… I wonder how much of a cheat sheet I can fit onto a battery wrap? Off to the skunkworks I go!

[BlueSwordM]

Yes. It has no problem fitting in the space between the tailcap and the tailcap spring board.

I know that because that’s where my manual is.

Well, you could split it up across four batteries if necessary.

perfect modes for any lantern

We should never underestimate the importance of having adjustable-tint high-CRI momentary bike flasher mode in a lantern. I mean, it would be totally useless without that. How else would we stutter-signal to others while riding down the mountain in our bike-mounted camping tents?

From now on I will refer to that mode when implemented on a lantern as Penny-Farthing mode.

Its been a long wait, i am very excited it’s almost done!
Do we thin o a 30q would suit this light, or we’re best with sofirn battery?
I use 30q in my q8, and armytek lights.

[BlueSwordM]

A 30Q would be about perfect for balance between cost and capacity for a high drain cell that can both be used in the Q8 and BLF Lantern, if they stay in pairs of 4.

I hope I’m not too late, but I’ve finally been updating the diagram to make a lantern-specific version. Here’s what I have so far:

Thanks Toykeeper for the updates and new manual Andruil diagram :+1:

@DBSAR — add it to the first post please. The group, esp newbies shouldn’t have to read the entire thread to find the UI manual

TK - I’ll shoot you and DBSAR the full color logo files I have if you want them for the manual.
Speaking of the manual, I’ve been trying to condense it into something easier to fit on the back of one or more LT1 battery wraps. Does this look accurate so far?

Don’t mind me - I have no idea why the formatting is all janked up - working on it

1 = click, release
1H = click, hold
2 = click, release, click, release
2H = click, release, click, hold
etc

I’m interested in one!

[lunchbox]

I’m interested in the lantern!
Just got a FW3A and learned about BLF, totally thrilled with what you all are accomplishing here.

I got a bit distracted last time I tried to catch up on this thread… but not today. Apologies for the delay in responding to posts.

@DarkShot

Random thought: A multi-emitter EDC light with tint ramping capabilities would be neat. Likely not possible in a D4/FW3A formfactor I’d imagine given the limited driver space but it’d be really cool nonetheless.

It should be possible in a D4. It even has a good number of LEDs for this purpose, so it can have two of each. It’d basically just need the MCPCB and driver redesigned to have two separate LED- outputs, and the firmware would need some extra code to handle four power channels instead of two. Not sure how hard it would be to fit everything onto a D4-sized driver though; it’d probably be necessary to omit the RGB aux LEDs to make room for the extra power circuitry.

I recently saw this in Sofirn’s FB page:

Sofirn color-temperature-mixing EDC flashlight

It seems to use nearly the same LEDs as the BLF LT1 lantern (LT1 plans to use 2x LH351D 2700k + 2x LH351D 5000k); this teaser color-temperature-mixing EDC flashlight is supposed to use 2x LH351D 2700k + 2x LH351D 6000-6500k.

Probably transfer the Anduril firmware to an EDC flashlight?

[amishbill]

That’s an interesting technology transfer. The hardest part is probably transferring the LT1 driver design into a smaller footprint. Then again, if their engineers were looking ahead, there’s no reason they couldn’t have designed the LT1 driver from the start to fit in other shells. Hmmm…

I’m not sure of their market though. How many people outside of the enthusiast community will really care? Well… maybe photographers who want portable fill lighting they can match to ambient.

It could be possible that they are wanting to try the LT1’s tint ramp design-concept in a flashlight form after learning how well the LH351 series works with the tint ramp high-CRI range. I like the idea of that as a flashlight too. If Toykeeper’s awesome Andruil-LT1 firmware was incorporated in such a flashlight, i would definitely be interested in one myself. :+1:

They posted a teaser video for that a while back. If I understand correctly, what happened was:

• BLF sent a lantern driver design to Sofirn
• Sofirn interpreted the design as a guideline, and made their own version of it
• BLF insisted that Sofirn use BLF’s original design in the lantern
• Sofirn still wanted to use their version for something, and scaled it down to use in a smaller light

Otherwise, I haven’t really heard anything about it except the teasers Sofirn posted. I don’t know what firmware it uses, or if it is reflashable. I like the design, but it would have been nice to be included in the process since it’s directly based on BLF’s designs.

In any case, I hope it’s reflashable.

[charwinger21]

Too late to get this into the LT1, but for the LT2 it might be interesting to potentially use the same pogo pin layout as the D4v2 for software updating.

Good points. I haven’t heard much on it or that light’s specifications.

Hello.

I am interested. Put me down for one.

I am new and joined to get in on it and support what you are doing.
