When will the accessories be ready? I think that DBSAR said that he was going to make a video to talk about the accessories but I probably missed the video.

In the mean time i know, i need to get my butt in gear & make time to finish developing & testing some of the favorite accessories for the LT1 to create the accessories video for my Youtube channel, and see if we can get an “Accessory Kit” rolling for it.

Hummm….I thought that a person could only buy 1 unit at Ebay. I’d like to know the outcome of that offer.

best I can tell there are no personal codes required for ali or ebay. see Sofirn’s post for the details.

OK, I made an offer on Ebay (as per instructions in post #7717) for my first (#53 on the interest list). Let’s see what happens…

My “offer” on Ebay was accepted, so I payed.
Now for the wait…

I believe sofirn did limit to ONE per PERSON . So max you can offer is 1; I dont think Sofirn will accept that offer. I could be wrong but in the description it does stated 1 max.

I’m on the list for 7 — So I submitted an offer for 7 on EBay. Just waiting for acceptance then pay.

In the comment section of the offer I put my Forum user name and the 7 slot numbers from the BLF list so they can verify and approve.

The first round of orders is limited to one per person. You should expect your offer on 7 to be rejected with a request to lower it to 1.

When the second round is released, you should be able to place multiple lantern orders.

I’ve been following the thread closely all year, but I thought that the only real difference between the first and second batches was the manual. What are the other differences?

The major difference is the option to get the LT in something other than black. There are also some driver upgrades that in my opinion would never be noticed by most people.

Does anyone know if the 3000mAh Sofirn batteries offered during the GB are “protected”?

It appears that the cells offered with the GB are these same 3000mah ones available on Sofirn’s AE store, and if so, they are protected. I’d say it’s a safe bet that they are protected.

I have yet to see protected Sofirn cells. None of the Sofirn lights I have came with protected cells. Unless I’m blind the link you supplied is to unprotected cells as well. From my testing Sofirn cells are not something you would buy on purpose. Capacity is OK but only at extremely low amperage. Max amperage is about 2.25 amps which is well horrible.

Well maybe you are blind. The name of the listing is

Quote:
Sofirn Rechargeable 18650 Battery li-ion Battery 3.7V 3000mah 18650 Cell Rechargeable batteries with Protected PCB Board

And the image of the cells has in red text 3000mah 18650 protected battery.

if you buy purchase batteries alone, there are protected version and unprotected version. Since sofirn lights are protected, the KIT is including unprotected batteries.

Thanks for clearing that up Barry Thumbs Up

Any idea when the personal codes will be sent out for the first 500? I’m in at 419 and 420 and would like to buy through Amazon as I have a gift voucher to redeem…

What is the story with the “Batch 2” (with firmware corrections)? What was corrected or changed and how does a person know which one to get or which one they will be getting?

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.

My two last remaining questions are still opened:



  1. Can somebody help me on the “Switch Backlight“ chapter. I’m confused of the behavior, and don’t want to translate something I’m not sure of getting.

  2. Can somebody detail me this paragraph from the “Ramp Configuration“ section: Note the default (after a battery change or other power interruption) for LT1 setup the smooth ramp will turn on at level 65.  For the stepped ramp, the output level choices by default are 10 / 45 / 80 / 115 / 150. The LT1 will turn on at level 80 by default.  Once the floor and ceiling levels of the LT1 are changed as described below, the LT1 will remember these changes even after the power is interrupted.  After the stepped ramp is changed the lantern will come on at the programmed level closest to 65.

    1. Why does STEPPED and SMOOTH does not share the same default (65 vs. 80)?

    2. What are the various defaults for SMOOTH? Or on the opposite why are there multiple defaults for STEPPED?

    3. Why does the STEPPED RAMP would want to be as close as possible to level 65 on start after a programmation?




They are needed so I can fully finish the translation.

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.

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.

I’d rather have a 2nd batch light.

Do we know if there will be any differences between the batches? Small corrections, improvements, anything like that?

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.
