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

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.

Put me in for 2 please. Many thanks in advance…

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.

can i get added to the list for one so sofirn can confirm for teh ebay offer.

Thanks

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?

Order successfully placed via ebay with cells. Thanks to all involved.

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.

Thanks for clearing that up Barry :+1:

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…

Anyone buy from AE ,any info how to get the group buy price ?

There is instruction in post 7717 as stated in the first post.

Please add me for 2 more, 3 total.

Thank You

Ordered thru Amazon, got my code from Sofirn. Thx TEAM!

THX!

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.
