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

LT1 arrived today 12/24 after ordering on 11/29 as a black Friday special. Less than a month is pretty fast. I couldn’t believe that I got it for $53.xx after using multiple coupons and codes, until I saw it arrive. That’s with batteries!

Thank you to the LT1 development team, at both BLF and Sofirn.

Yeah… I don’t picture the wife being too interested in that lol

Mine is in shipping limbo too. Ordered November 21st, “shipped” November 29th, and that’s the only information that Amazon has. Both “aftership” and “17track” show nothing for my tracking number. :-/ Since it has theoretically been shipped for almost a month, I’m hoping it just pops up at my mailbox.

Merry Christmas and a Happy holiday season everyone! :beer: :beer:

Very politically correct.
It is Christmas for me, but thank you anyway.
Wish all of you the same

Merry Christmas everyone!

Here’s my lantern:

I am so pleased with it, it’s easily the best light-related piece of equipment I ever got hold on since I’m into flashlights. Thank you DBSAR, ToyKeeper, SIGShooter, Sofirn and all others who have made this possible.

I recommend this case for JBL Flip 4 Bluetooth speakers:

Not only does it fit like a glove, it also provides storage space for the manual, spare O-rings and the charge cable:

If you look closely, I added some O-rings outside. The top got a 60x5mm ring, which sits really firmly and should provide good cushion in case it topples over. I also put 40x2.5mm rings over the base to provide a better grip.

And, in case someone is interested, here’s how I modified the USB coding:

I found my charge end voltage to be 4.17V, which is perfect. A bit lower than 4.20V is always good, as it stresses the cells less. I also found the voltage indicator to be extremely precise. I supplied voltage with an adjustable lab power supply, and just as the voltage changed from 4.04 to 4.06V, the lantern changed from indicating 4.0V to 4.1V. Same when going from 4.14V to 4.16V.

Speaking of the usbc port, what the input voltage range?

Essentially the same info. No further updates after the 5th.

The TP5100 ranges from 5V (or a bit below) to 18V, and 18V should really be the maximum with no headroom.

Awesome, thanks. I had seen some posts earlier in the build about it, but couldn find them again. It just got way more usefull as an emergency light.

That’s what usually happens to my packages until they suddenly appear at a US sorting center. (customs) In my case it’s Chicago.

Mine will most likely be Chicago as well. I guess I’ll just keep waiting.

Merry Christmas everyone!

I got my code to buy my other light(s?), but with cells only. I had to reply to request a code for no cells. I haven’t heard back yet but I’m in no hurry.

The rubber bumps for feet is a really clever idea!

Keen eye! I use those on all kinds of gadgets, as they are very cheap:

Fixed it, its Christmas for me too. :smiley:

Thanks for the info and pics, does anyone have a recommendation for a good place to purchase O rings like the ones pictured(in US)?

TIA and Merry Christmas!

If you have a little patience:

Did you use 45-mm-x-3-mm or 40 x 2.5 as you previously stated?

The inner diameter is 40 on mine, the 45 one from ebay is measured at the outside, so its 39 inside which is ok. 2.5 width is what I had at hand, but the grooves are slightly wider than that, so 3 or even 3.5 would also work just fine.
