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

I’m not exactly sure which version is in batch 1, but if it is new enough, it should be possible to check the version by clicking 15 or more times from off. Then it should blink out the build date.

Batch 2, I think, has firmware from 2019-10-02. This simply made the “muggle mode” capable of going one step brighter. It’s a really minor change.

More updates could come later, but they haven’t happened yet.

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.

How much did the shipping cost? (I also live in Hungary.)

Follow the instructions which are now indicated in the OP.

Write a message on the order to indicate your BLF username. Then “Place Order” but do not pay yet (you may need to select “Other Payment Methods” in AE, for you to be able to Place Order but not Pay. After selecting this option, you can go back to previous page but the order will be placed, it should now read “Confirm & Pay Order”, which you shouldn’t do, until Sofirn adjusts the price to the GB price (wait some time), then proceed with payment when price has been adjusted.

At least that’s how I did mine.

I’m on the interest list at position 408 and 557, but didn’t receive any code via PM here (I wouldn’t order from Amazon anyway, so the code likely won’t be useful for me…)

My order has been assigned a tracking number now in AE.

Ah, I see. EUR 45,59 was the total cost, with free shipping. That’s very Cool! Thanks for the clarification.

Please also put me in for one more.

And ridiculous on a lantern. :stuck_out_tongue:

If I understand correctly, batch 2 has slightly newer firmware and an updated manual. There will probably also be green and sand colors at some point. I’m not sure if anything else is expected to change.

The Q8 had significant improvements between batch 1 and batch 2, but the LT1 seems unlikely to work that way since Sofirn now has years of experience with this type of design. My LT1 prototype is a production-quality item, and things have only gotten better since then.

I’ll probably wait to order, but not because I’m concerned about quality. It’s just because I already have one and I want someone else to be able to get theirs sooner.

Ouch. I’m sorry things turned out that way!

Thanks @d t a, I follow your advice and I got the tracking no. in the same day that very fast base on previous buying it should take 5-7 days to arrive :sunglasses:

I’m interested.

Is there any way to reset the color in the center or an indicator blink in the center like at each end

Please put me down for one. Thanks!

So I went to eBay, submitted a counter offer at the group by price. Sent them my blf username through eBay messaging, they accepted my offer this morning… I paid for the light and it should ship mid November

Number 100 on the list, got the Amazon code for LT1 only, ordered with smile.amazon.com for donation to our church, so the NY state sales tax was worth it!!

Over 3 1/2 years in the mak'n, Thanks to everyone involved!!!

Does anyone know what happens to the price of this flashlight? Tonight, its price in the official Sofirn store on Aliexpress was $ 104 (94 Euro), now it is - $ 71 (64 Euro). What is the discount for forum participants? From what amount should it be considered?

From the first post:

> For the BLF LT1 lantern, ( without-batteries) the GB price is to be $49.99 USD. > For the BLF LT1 lantern, (with four sofirn 3000mAh 18650 batteries) the GB price is to be $62.99 USD.

Yes, on Amazon I paid $49.69 plus local tax ($4.29) with the code they pm'ed. It's not on Prime however, says in stock, arriving Nov 7 - Dec 2, hoping it will be sooner.

Instead of participating in the mad frenzy for getting a lantern ordered as soon as possible (I could get trampled), I intend to let Sofirn fill my order when they get to it. It only makes sense since the folks here have gone to all the effort to coordinate the GB for us and I don’t need to try to “cut in line”. Frankly, I don’t undertsand the frenzy at all. It’s been almost 4 years and I’ve gotten along without one in hand for this long, does another month or 2 really mean that much? No, or at least not to me.

Maybe if they are gifts and I need to have them for Christmas, that might make the difference for a shorter delivery time.

Thanks to all involved for doing what you do and also for tolerating the “madhouse” that the GB has become. It’s amazing what volunteers can accomplish and I must admit I couldn’t do what you folks do for us, or I couldn’t do it for any length of time without losing it. I’m trying to say “Thank You!”. (I’m just reading and I’m beginning to lose it, hence this post.)

Calm down folks! After you all trample each other, I’ll step over and around the trampled and bloody bodies and calmly take possession of my lanterns requested in the GB and without the frenzy. You can do the same. Life is so much simpler and longer without the rise in blood pressure and possible adrenalin dump. It’s not life and death, just a light, albeit a very nice light.

Also, interested for 1.

I’m guessing that when the second batch lights are ready, we’ll get new links for the sand and green versions. I have my first order code, but I’m waiting on the codes for the lights I added later. So, I probably will just wait to order all together, and I might get colors other than black when I do. As excited as I am, I have to be patient I guess. :innocent:

Question here. The batteries, have to be button top? or will any protected 18650 work?

I had no problems with my e-bay order for one without batteries, took about 45min
Looking forward to this one.
