Thanks for the explanation. If I understand correctly the pads 4 and 5 are connected with two resistors and the pads 6 and 7 are not. So if I want to unlock all the power I just have to solder the pads 6 and 7 like I did in the old version.
Yes, thatās right.
Many thanks 
Sofirn I signed up for a group buy for two, but bought one. Will I be able to get a discount on the new version?
Donāt you think itās too much overhead to maintain the quantity used by each signators ? Much simpler, Sofirn is giving discount codes regularly openly or through a PM . I was late to the party but i got the same price .
+1 on this. Iām holding out until a 4Ć21700 model is released.
Forgive me if this has been asked.
Is there a plan to have the 18650 version have power bank functionality?
My question is whether or not there anything concrete about a version 2 of any kind or is this all simply theoretical; a wishlist?
Nothing concrete at this time, but everyone is aware it is a frequently requested feature. DBSAR and Lexel have both needed (and very much deserve) some time off from projects like the lantern, so I would not count on any updates in the immediate feature.
Wow, thatās awesome!!! Can you share any details about the implementation? If not, I hope @Lexel can, I assume this is also his design.
E.g. will they support USB-C PD (quick charging, with multiple output voltage levels), or just a standard 5V/3A output?
Will the same, single type-c connector be used for power input and output (i.e. type-c dual-role-power, DRP)?
Will the charging controller (TP5100) remain the same in this revision, or will it be replaced, maybe with a fully integrated powerbank controller IC?
Can the light and the power output features be used simultaneously?
Just got 2 lights. Using both off grid 4hrs per night on medium. Voltage drops .1v each night. Should get 10-12 nights runtime. Such awesome lights. Have told friends to buy them.
Questionā¦ā¦
1. Can a 3/4 second delay be put on start so that when clicking functions it doesnt flash light in face? During 3/4 second delay if second click is inputted it cancels out white flash.
2. Can battery meter be moved to orange button?
3. Can one warm led be replaced with red and 3rd flash during warm tint ramp function setup activates the 1 red led at 1 lumen?
Thatās all that Sofirn mentioned in a group chat 
Hopefully theyāll shed more details on things soon.
1. There is a compile-time option to change the response timing while turning the light on. The driver is pretty easy to reflash with a SOIC8 clip or one of Lexelās pogo pin adapters. Soā¦ no, that isnāt going to be implemented in the official firmware, but yes, you can probably modify your LT1 to make it behave as described.
Specifically, in the config file, change B_TIMING_ON from B_RELEASE_T (the default) to B_TIMEOUT_T. This tells it to wait until all clicks have resolved before it responds. Nobody Iām aware of uses this option though, so it hasnāt received much testing or maintenance. It may need to be updated to make sure it still works.
2. The firmware has support for indicating battery status with RGB LEDs in the buttonā¦ however, the LT1 doesnāt have RGB LEDs or enough pins on the control chip to handle something like that. So it would require pretty big hardware changes.
As an alternative, it should be possible to modify the battery check mode so it would only blink the button LEDs and not the main LEDs. But this is not currently implemented, so it would require modifying some code.
3. There has been some talk about adding a third power channel for red LEDs, and adding a set of red LEDs plus the driver hardware to power them. It would be reasonably straightforward to add to the firmware, too. But I havenāt heard any confirmation about it actually happening.
The LT1 itself doesnāt have the hardware necessary; it would require Sofirn to change the design and manufacture new parts.
So itās a āmaybeā for a later version (LT2?), and a ādefinitely notā for the current version (LT1).
Thanks for the detailed info. Well I will buy 2 more of the lt2s then. I love the light the way it is. My requests would make it the perfect light. Its a 9.8 right now. Thanks for all the hard work on designing and testing.
Ok so the future requests areā¦ā¦
1 red led on 3rd tint ramp channel
Orange push button voltage remaining blink (instead of main led)
Short delay before main led comes on to accept button requests
Direct to red with one loooooong press. Low red maybe 1/2 or 1/4 lumen. Not some gosh darn 300 lumen red.
4x 21700 batteries. Or teslas new 4598 cells 
(only 1 required) 350wh per kilo
Oh and maybe bluetooth so I can access on/off sitting on sofa 10ft away.
If red is added, itāll probably be a complete third channel with multiple LEDs and a brightness range similar to the white modes. Most likely, itāll be possible to do all functions in red mode, since itās basically just a different ātintā. However, there might also be a shortcut to red or white from off.
This all depends on whether it actually gets built though. If Sofirn sends me a prototype with a red channel, Iāll make the firmware for it. But I have no idea if that will happen.
Regardless, Iāll probably want to switch the UI to Anduril 2. The basics are the same, but it has all the disco modes and config options blocked by default. Those are only available after unlocking advanced mode. The defaults are much closer to a ānormalā flashlight UI, so that hopefully people will be able to use it without reading a manual.
Complete red setup would be great.
One thing that could be improved is the user manual with lines pointing everywhere. Im an ex IT guy and I found it confusing and clustered. A really nice clean āif you want X do X line by line would be an improvement.
I saw the cheat sheet. The fact that there is a cheat sheet makes my case for a re-do.
All that is part of next version and improving whats already an awesome light.
I am going to buy some as xmas gifts.
By the way we are off grid idaho up in the forest. We use 2 lt1s every night for about 5hrs per night on medium setting. The lanterns are using .1v per night. 6 nights in on 1 set batteries 4x3500 and we still have 3.6v remaining. Amazing!
Thanks for an awesome light.
Does anyone know the amp draw of the low and high orange button light? Would it even matter over the 12 days runtime I get?
Crossing my fingers. Having the red LED option would really make this the ultimate camping lantern
I agree but it needs to go low enough too. Just having red isnt great if its 10 lumens at low. I have 3 red heaadlamps and only 1 has 1/4 lumen red which is more light then I want with night adjusted eyes. Maybe 1/8th lumen low and ramp up from there. Remember red is to save night vision and give just enough light to accomplish dark task. In my case 1/4 lumen is the perfect nightlight I can set in the hallway.
Red Camp lantern isnāt to save night vision, a dim white light can do that, ask any pilot. Itās to have light without attracting bugs at the campsite
