I remember a list in alphabetical order of username and your numbers on the list.
Does anyone have a link to that?

I think this is the one you are looking for

That is it.
Thank you.

Thank you. Black is fine but I didn’t understand all the rules

So finally I got some lull so I was able to make the mod to the LT1 so that it charges from USB-C to USB-C.

It is doable but it isn’t easy

Cable works in both orientations. I have tested with only one AC adapter but it the one that obeys the USB spec so it should work with any that does so too.

I have charged from 3.9V to completion and there doesn’t appear to be any issues, couple of minutes before the green light the cells were about 4.172V

I have taken one picture but frankly this isn’t the best of my work. And the pictures don’t show much

If anyone is interested I can put more detailed description of what I did and what to do.

Sorry, I haven’t been able to find much info on this… why is this necessary?

It’s not

[spinynorman]

It’s not really necessary, it’s just a hack to get around the fact that the USB-C standard…isn’t standard.

The good thing about standards - there are so many to choose from.

Sofirn will make sure every single person get code for one unit. Then go back to rescan the list and send new codes for those who want more than 1 lantern.

I looked a few pages back and couldn’t see a reference, but I just received a code and was down for 6 lanterns. Will the code only work for 1 lantern? Also, I don’t want to be an a-hole and order more than I am meant to initially. Am I expected to order just 1 unit at this time?

Never mind. I have found the answer.

I have checked sofirn account messages. A single-used code was sent to you in the beginning of Nov. But you asked for 10 units.

I am sorry to tell you, for now, you can only buy 1 unit. You will need to wait to buy the rest 9 units.

To all BLFers, I apologize if sofirn account didn’t do a great job communicating. Because new staff named Lan Lee, who is a young girl graduated months ago, is using this account. I appreciate your understanding.

[Tech25]

Got the code and placed my order. Thanks to everyone involved in this, I can’t wait to get it!

[XOThermite]

My first lantern was at #1355, I just got my code. Fingers crossed it might arrive for Christmas. I’ve been watching this from the beginning, Before I signed up I decided to check the quality of 10 Sofirn flashlights. Fair to say I like Sofirn flashlights and I’m sure going to love the lantern. LT1 team thanks again for all your hard work - I for one really appreciate the marathon effort you have put in.

Just one datapoint but maybe it is of interest to people:

I loaded the LT1 in “”lighthouse setup”:https://budgetlightforum.com/t/-/38215/8729” with 8 Sanyo GA cells and let it run on 1x7135 chip at 2700K. The output was about 75 lumen (not super bright but a useful longterm light level to light an area) and although I did not monitor it all the time, after about 70 hours the output stepped down. I stopped the test at 80 hours (I had a visitor last night who slept in the living room where the lantern was), it then was still running on low output. The batteries were all 2.96V.

I think this is about what the numbers tell you , when you divide 27 Ah (8 GA’s) by 0.35 A (one 7135 chip), you get 77 hours. But it is nice to see it in practice.

Can i get a code please. Want an orange one so…

[jigsaw]

there are no orange ones.

I don’t see you on the interest list which Sofirn is operating off so they may not send you a code.

I got a different lantern today. A few weeks ago I found an Aladdin no#23 kerosine lamp on a flee market for a mere €4.50. I felt lucky but did not know yet that it needed a new wick and a new mantle, and some kerosine of course. So now I’m another another €35 down the road but today the wick came in and I got it working. The output is a bit less than the LT1 but it looks pretty (and makes me feel a bit “prepared” :party: ).

I suppose it supports a candle flicker mode?
How’s thermal regulation?
Which standard of programming pads does it use?

I tried twist-twist-hold the knob and although that does something to the brightness, the output keeps steady. It seems I can’t find candle mode on this lantern, and it does not seem to have any flicker.
About the thermals, at highest setting (which does not impress at all) you can feel it radiate from 2 meters away, some component produces a lot of heat in there.
Programming is a pain, I tried smoke-signalling the newest Anduril but to no effect. The ramping of the stock UI works very well and intuitive though.

[Sento]

is it possible to buy it on ebay if I message them if they sofirn already messaged me the amazon code to buy? Just weighting my options

[HONDARIDER]

Got my code and ordered today. Man that took a while. Glad to see they are complete and shipping.

[flasky]

My code doesn’t work at Amazon.de and Amzon.com isn’t shipping to germany.

An ideas folks ?

[christoph]

Got my first code today for amazon ordered without batteries cant wait

My apologies for not keeping up with the thread. After realizing I wouldn’t be ordering from the initial batch, I decided to just wait patiently for my code.

Now that I have received it, I have a couple questions.

Does the code expire? (I recall seeing something about 30 days, but didn’t know if this had been confirmed)

Has manufacturing of any of the additional colors been confirmed? And if so is there a timetable for their release?

If I can purchase the lantern in one of the top choices from the color poll, then I would prefer to wait (assuming my code doesn’t expire before then)

Thanks in advance for any helpful responses!

Yep, expires in 30 days.
No colors have been confirmed.
Not so sure about the waiting for a color option as it may well be colors could be exempt from the group code discount due to their delay (if we get them) - perhaps someone else can help shed some light on this.
