Does anyone know how to differentiate which of the ground (black) cables from the new (with power bank) driver connects to the warm and which to the cold LEDs?
Since the manual PDF file on google is offline, who knows where to find it now?

Hereâs an Anduril 2 graphic for the LT1:
If you are looking for the original LT1 manual (and other Sofirn manuals), please check here:
I had to redeploy my files on Google Drive because the old links did not work anymore.
If you are looking for the manual of the new LT1 with AndĂșril 2, I need to ask you for patience. It is work in progress already. I do have a manual that Sofirn made on their own and that is currently being supplied with the new LT1 version. But there is a lot of wrong or missing information in it, itâs not worth putting it onto the sharepoint.
These versions are known:

|Sofirn A2|11.07.2021|https://budgetlightforum.com/t/-/38215/11595\|
Any more known board versions out there?
And what are the differences?
In a nutshell, is Sofirn A2 the âbestâ release of the LT1 thus far?
Also, if someone is OK with Anduril 1 and doesnât intend to leverage the power bank feature, is it preferable to get the earlier version? Iâm really concerned about all of these intermediary board changes. And Iâm sure with the way things are, you canât request a sub-version, only the LT1 Anduril-1 or LT2 Anduril-2.
My Sofirn 1.0 LT1 has limited power bank capabilities. It doesnât work with Apple USB-C to Lightning while the Wurkkos HD20 works with the cable. Itâs also on Anduril 1 without version check.

Good to know this. Has anyone found that Sofirn A2 avoids that problem and a USB-C to Apple Lightning will charge an Apple device (iPod, iPad, iPhone, etc.)?
Where is the cheapest to get a Sofirn lt1 these days? I donât mind getting version 1 without the power bank.

Cheapest would be from Sofirn store. But you have to consider shipping as well:

Thank you. Ordered the brown one in Sofirn website.
Hi There. I could really do with a little bit of help.
I bought myself an LT1 Anduril 2 in that really wicked on the eyes orange colour.
Anyway, my problem is that my LT1 will not allow me to set a timer in candle mode.
No signal flashes and also no time attributed to the number of button presses.
I now have a new problem called âAnduril 2 Thumbâ
@Fruityfrog
Assuming youâre already in advanced UI (not candle mode otherwise): click five times and hold the last one. The light will flash every second, each adding five minutes to the timer.
I got the Sofirn v1.0 and BLF-LT1-A2.
BLF-LT1-A2
- The green power button light is on even when itâs in use. Itâs necessary as itâs hard to find the button when you need to turn it off. Itâs distracting.
- Power bank works with my USB-C to USB-A adapter for iPhone
Sofirn v1.0
- The amber light will be dim when itâs on. Itâs too dim to be useful when I want to turn off my LT1.
- Power bank doesnât work with my USB-C to USB adapter for iPhone
- Power bank works with USB-C to USB-C, I can power the SP36
- Anduril 1
I like the Sofirn v1.0 during standby. I keep this in the corner on a selfie stick with tripod mount. With the button towards the corner, it would reflect a very nice ambience light at night. Itâs frankly easier to turn off the LT1 with my index finger when the button is away from me.
I will update it to Anduril 2 and see if the power bank will work for iPhone.
I just ordered an orange LT1, but that green light is making me change my mind.
This chart is incredibly useful.
I ordered a BLF LT1, supposedly the older model. Itâs brown anodized. I received it and clicked 15 times. It showed flashes: 2 long, 1 short. Thatâs Anduril 2.1. OK, this is interesting. EDIT: Iâm wrong, this is not Anduril v2. No wonder why I heard laughing from the stage wings⊠It took ToyKeeper to step up and tap me on the shoulder.
It turns out that I have the 2nd driver example, revision 5.0. My understanding is that this is the LT1 v1, with Anduril 1. I do have USB-C to USB-C, but discovered that itâs one wayâto the LT1.
Did all of the rev 5.0 LT1âs end up with Anduril 2? Or was there some slipstream change at some point? Either way, Iâm stoked! Saved me time & trouble of having to upgrade it.
Btw, the included manual stated that while charging, the switch LED would be blue. Itâs not. Itâs red. And actually, I prefer that. Who does blue WHILE charging? All of the lights Iâve had with e-switches and on-board charging shine red while charging, then blue when complete.
Question:
The battery level indication range is set for the voltage of a single 18650. So Iâm presuming that what we see is an average taken of voltage across all cells? Certainly not cumulative, as youâd see on something like the Nitecore EA41 (4 x AA). Seems like thatâs the case, as at times when Iâve selected the status (3-clicks from off) Iâll get a lower number first, then the 2nd display shows a higher number (as if adjusting for total voltage assessed across 4 cells). At first I thought it was âmaking the roundsâ showing the levels of each of the 4 cells individually, but the lower number never appeared again after cycling over 4 times.

Since the batteries are in parallel they all have the same voltage. Or am I not understanding your question?

I removed the 18650 cells and checked them out in my charger, individually. At the start of charging, I had 3.65, 3.71, 3.76, and 3.77. In the LT1, the power check showed 3 long flashes, and 7 short flashes. Then became 3 long, 8 short and continued to show that with repeated checks as it continued charging. But I get it now. By virtue of the parallel circuit, the voltage is inherently averaged out across the 4 cells.
Any difference in voltage readings that are blinked out is caused by the tolerances in the components in the circuitry.
The cells are all in parallel, unlike the mentioned Nitecore AA light. Cells in parallel will all settle to the same voltage even if the cells that are newly inserted inserted are at different states of charge. There is no way the only one cell could be sampled when other cells are in the light at the same time.
EDIT: okay I see a post was added before I finished typing.
Hi Everyone! I'm new to this forum. I recently got the BLF LT1 after seeing it here. Thank you all for this wonderful light. I got the BLF-LT1-A2 driver with green standby led, USB-C power delivery. Out of curiosity, I opened up the driver and found an unknown chip near the USB-C connector. There are two of them. I highlighted them in the photo below:
The marking reads 323GBAD? Do you know what it is used for?
Canât find any datasheet, but Iâm sure they are for charging and powerbank. Two for higher current.
