Why the manual didn’t get sorted out before the first batch is beyond me. I guess there just wasn’t enough time in the 3.5 years of development. Even after myself and others took to correcting it still had fundamentally wrong information about the operation of the LT1 because the people who knew how it worked and wrote the software or had samples didn’t bother to review the manual for basic correctness while we were tuning it for readability, grammar, and English.

I also don’t understand why the firmware is still changing. Why couldn’t it get sorted out before the light went into production? Did Sofirn put the light into production without telling anyone as a big surprise?

It will keep changing too. Do not stress about it. With the flashing key possibilities there is no reason to not keep developing it. The version that’s shipped should suffice either way!

There is a very long answer to explain the exact details of that Stereodude, but without being involved in the lantern the summary would be: it has to do with how little control we have over what happens in China, difficult communication over language and cultural barriers, and with launching a new product in general. Maybe also with group pressure getting the thing done before every last little detail was sorted out , which may or may not be a bad thing.

That said, it seems to me that this lantern still is the most thoroughly done BLF project to date.

It’s the nature of software to evolve over time. People request improvements which get rolled into future releases. In this case the changes are minor and I suspect that the vast majority of people will never know or care about the 2 versions.

Sofirn did not spring a surprise and put the light into production without the team knowing and approving it.

The LT team did bother to read it and saying that they didn’t is a big disservice to them. Rather than wait another month or 2 to have the manual catch up with all the corrections it was felt that it was ok to release batch 1 earlier so that people could start getting the LT.

I bet if the buy was delayed just for the manual changes that people would be complaining about the delay.

None of the LT team, other than Sofirn, is making any money off the lantern or is doing this as a job so the development time is largely due to that.

Besides, the updated manual can be download as noted somewhere in this thread. And it’s just a lantern, how complicated can it be to read the on-line instructions a few times and then configure it for what one needs? My guess is that for many users after it’s been configured it’s going to stay that way for a long time.

Just my thoughts:)

So, for example, why did the manual say the default mode was the smooth ramping mode when it is actually the stepped one? How did such a basic error not get fixed until after sbslider, myself, and others spent hours working on the manual?

Not everyone who is going to get one of these lanterns to use has been following this thread from the beginning. Someone who I give one of these lanterns to as a gift isn’t expecting to have to go online to read a corrected manual or flash the firmware in their lantern because the shipping product wasn’t quite done.

Reading it and having Sofirn make corrections are not one and the same. Also my career was in programming and I’ve seen many cases where manuals were wrong even when they were worked on by paid professional technical writers.

So your claim is it was right before and that Sofirn changed the manual introducing errors into it after the LT1 team reviewed it? Facepalm

If Sofirn is to blame for all these things maybe the LT1 picked the wrong manufacturing partner.

Pretty sure that’s not what he is saying.

You seem like you’re almost looking for crap to be unhappy about.

This is basically a volunteer project for everyone except Sofirn. You’ve got a bunch of people volunteering their time and efforts to design and produce this thing and dealing with people in another country who may or may not speak the same language super proficiently who need to actually make the final product.

And the you have all of us providing pressure to get it out as quickly as possible.

And you’re somehow shocked and dismayed that there’s been some changes or minor issues in that process?

There have been only 3 manufacturers prepared to work with BLF over the last 5 years, Manker (stopped doing that), Lumintop and Sofirn, of which only Sofirn trusted BLF enough to make almost exactly what the BLF team wanted, and that trust took more than a year to develop during the Q8 project (via Thorfire). This is now their third project, and the most risky one for them because it is a relatively expensive product and about everything was completely newly developed which is costly for a small flashlight manufacturer. I think that it worked very succesfully for BLF and hopefully for Sofirn too.

[...]About the level 65 thing... It is behavior inherited from other lights which use the same firmware. On many of them, the default ramp goes from 1/150 to 130/150, and then there is an additional turbo level at 150/150. When it turns on, it tries to hit 65 because it is visually halfway up and makes a good "medium" mode. On the lantern, there is no turbo by default. It's not bright enough for that to make sense. So the ramp goes from 1/150 all the way to 150/150. It still defaults to level 65/150 after a battery change though, since it's still a pretty good "medium" mode. It uses the stepped ramp by default though, which goes from 10/150 to 150/150 in 5 steps. Normally I set the default to 7 steps, but that is probably too many for this light. Also, the default floor is slightly above moon because moon is probably too low for most lantern purposes. Also because moon has no tint ramping, and I didn't want that to confuse people. On that last point, the number of tint steps available at any given time is related to how bright it is. The resolution gets coarse at the bottom of the ramp because of math. If there is only one unit of brightness, it can be assigned to the warm or cool LEDs, and those are the only two choices. If there are 2 units of brightness, it could be warm=2, cool=2, or a mixture of both (warm=1, cool=1). Then it can get 3 tints. At brightness=3, it can do 4 tints. And so on. It the top, there are 254 different tints. Represented visually, it looks something like this: So the default floor is high enough to provide 9 different tints, if I recall correctly. And as it gets brighter, the number of possible tints increases. Anyway, the default after a battery change is level 65/150. If it is in stepped mode though, and there is not a step at exactly that level, it uses the nearest step instead. Of course, the default brightness after a battery change is unlikely to be something people encounter very often. The lantern never really needs its batteries removed. Also, if the user turns on manual memory, the saved level overrides the default. So the user can set the default to whatever they want. 65 is only used if the user is in automatic memory mode. Almost all settings are remembered after a battery change.

Thanks for the additional clarifications. To be sure:

  • Right now in the manual we have a "TURBO" referenced. Is it normal? And should we get rid of that and maybe just call it "MAX" then?
  • The default FLOOR for SMOOTH is currently described as level 1, is it right?

I love automation! I think there are plenty out there that don’t trust a computer for some reason. I see it in my work all the time. We were migrating 100+ email accounts and the powers that be decided a manual process (Office 365 web interface, point & click for hours utilizing several staff) was safer than a powershell script with testing and logging (seconds to execute the script and utilizing 1 staff member).

Another possibility is that maybe the process for getting the codes from Amazon is not super friendly/portable. I haven’t sold anything through Amazon, so I’m not sure.

Getting the codes is easy, it’s just that Sofirn elected to do it manually.

that won’t be possible with anodizing, only with cerakote, powder coat, spray paint… (orange)

Gentlemen – you’re forgetting one simple fact.

Factory flashlight manuals are printed in such a compressed format that they can’t be read anyway. The only copy that really matters is the one you find online and can actually read.

Ordered my first one with amazon.de with batteries.

Thanks all involved to make this happen.

I think this one might eventually replace my coleman unleaded on camping trips.

3 more to come. Most will end up as gifts.

This project really shows if you get together what you can achieve. Been looking at battery lanterns for ages, and they have all been s!!t. I really think the BLF community hit gold with this one.

To all those complaining, one advice, get involved earlier in the project and offer to help. If not, shut up and be grateful for those that stood out.

I believe Sofirn started with a manual from a previous Anduril light that was close, but not the same functionally and had different hardware features. TK has made a bunch of LT1 specific changes/enhancements to Anduril, and those were not included in the manual they used as a base. As English is not the first language (presumably) of Sofirn’s team, they may not have known any different (Anduril = Anduril right?).

I saw you posting earlier in the thread helping with the manual. It seems you really helped to sort out the inconsistencies and make the LT1 project even better, and many here will be grateful for that.

Tom what you don’t see as a frenzy with people scurrying around asking questions about ordering 1 light from Amazon with a generic (as far as I know) supplied code from a post here, I see as a frenzy. Different folks, different perspective, different lives. Doesn’t make either of us wrong as it doesn’t make either of us correct, or at least we’re correct from our individual perspective.
Just for the record, there was never a “generic code” posted in this thread that folks could use to buy a LT1 from amazon. Sofirn clearly stated in this very thread in this post how to purchase from ebay or Ali, and in this post that Sofirn had started to send out amazon single use codes. Prior to Sorfin sending out amazon single use codes, SigShooter sent out a group of amazon single use codes. Things got a bit weird for a bit, and Sofirn, bless their hearts, took on the burden of dealing with this task from SigShooter.

Yup, things got a bit weird, hence my use of the term generic code since I was unaware as to the source and I wasn’t going to go back and try to decipher things, hence generic.

There were issues due to time differences, etc so they went with that route.
