*BLF LT1 Lantern Project) (updated Nov,17,2020)

I “accidentally” bought one of the new ones, order a second LT1 in orange and was surprised when manual mentioned power bank and that it has a new driver when I opened it.

As noted already, no pads to control output.

Programming pads are totally messed up, I have oshpark pcb with pogo pins and had no idea I was getting an LT1 I could not program :frowning:

UK comment: Ali steals the tax! They charge the VAT citing Brexit but under declare the value on shipping and don’t pay the tax. I prefer the old way where no one pays the VAT…

It seems the programming pads are actually numbered 1-8. The way they are number indicates that they are a direct mirroring of the attiny85.

This is the pinout:

Of course, the chip can be easily programmed by removing the 2 screws and using a SOIC clip directly on the chip. As a matter of fact, the new driver has more clearance around the chip and is easier to programme that way.

What I want to know is, without the pads to control output, what is the output of the new driver? Have they removed the extra chips or are they connected by default?

Regarding UK VAT and AliExpress, I had not noticed! Horrible behaviour towards their customers!

You received a manual for the updated model? Lucky you :smiley:
Would you mind posting a photo of it?
I also bought the new, powerbank-equipped model, but no manual was included with it.
Of course I can get by using experience, common sense and Lux’s LT1-Andruil2 graphic manual. But I am still curious if Sofirn’s original document holds any extra info…

The Reddit link above shows all the drivers still, it does seem brighter than my existing one, assume all connected all the time?

Can take a photo of the manual, but your not missing anything madcrow it only covers basics and muggle mode

Sofirn Manual received with the latest version:

Back Page:

I am working on a new Andúril 2 manual (for LT1) already. Unfortunately, some last information on the configuration defaults for the new LT1 have arrived on very short notice. Moreover, I need to be careful not making a whole bible with too many pages. :FACEPALM:

I still hope for these two models (wishful thinking, of course):

LT1R - three-channel version (deep red - 2700K - 5000K)

LT1Max - 4-6x 21700 with PD charging (12V 3A), significantly larger head and > 1.200lm

I’m hoping more the other way with the lt1 mini…

Lux-Perpetual,

I can no longer access the PDF files for the Sofirn and Wurkkos Manuals that you had previously shared using Google Drive.

I receive "Error 404" when I try to access them which states "The requested URL was not found on this server".

Are there new URLs for the manuals or are they not being shared anymore?

Thanks, the PDF manuals were very helpful to me since I could magnify them on my device and easily read them compared to the tiny text of the printed manuals included with the lights.

Googles fault

Same :innocent:

Sorry about the broken links to those many manuals. It seems something got completely f#%&€d up with my Google drive. :person_facepalming: I try to restore everything when I find some time for it.

Thanks for the update.

Ideally the manufacturers would have manuals online but many do not. Besides being easier to magnify and read the online manuals, you also do not need to worry about losing the paper copy that came with the light since you can print the online manual if necessary.

Sorry I inadvertently spelled your name wrong, "Lux-Perpetual" instead of "Lux-Perpetua" but "Perpetual" does better describe your never-ending exceptional contributions to this forum, especially the detailed well-written manuals which will be everlasting.

So does this mean that this new LT1 version cannot be programmed with any Anduril updates?
Btw, can the LT1 original be updated to Anduril 2.0? I understand the power bank feature wouldn’t work…

Has anyone opened up the new version to confirm there are no further changes internally? I would hate to get the new one and not be able to install the Sunlike MCPCB for example.

I’m curious about the output of the “new” LT1. Can anyone confirm if the 7x 7135 are factory enabled and can it maintain full brightness throughout the entire runtime without having to step down due to heat?

Sorry & my appologies to everyone, things have been a bumpy road getting settled in the new house and trying to get back on track. I will be doing my best to get back into working on the LT1-Mini, a 21700 LT1-HD, (or LT2 model) and possibly a LT1-AA variant as Barry mentioned. Bear with me, its been a rough past couple years with the pandemic, big move, life changes, etc.

This shouldn’t be an issue since the updated LT1 still has two channels. I’m not sure what has been going on lately with BelMor, I hope everything is alright with him he is still on track to delivering our boards.

It seems to be a bit confusing as to what Sofirn is actually selling when you buy a LT1.
There seems to be 3 or 4 different versions on sale at the different outlets. ie Sofirm, Amazon & Aliexpress official Store…

Absolutely right and this new version with out any name change causing further confusion.

I’m quite bothered by the unilateral “updates” by Sofirn considering this was a community light. Altering the flashing pads in that manner is just a dick move, but changing the default 7135 configuration from 3x7135 to 7x3135 while removing the ability to alter it is quite significant and DBSAR should have been consulted.
