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

My guess would be faint white, like old type fluorescent tubes do for a few minutes after switching off. But that’s to do with electrical discharge agitating electrons, something that isn’t in play here. Interesting observation.

could it be the button illuminating the diffuser?

So I have the first batch lantern, thinking of flashing it to the new firmware. Any links to the parts needed to do this? Might just order a new version of the c to c is working. Or is the upgradeable too? Edited ,Amazon seems to be much higher on soic 8 test clip with usbisp , Ali is much cheaper but a long wait. A local shop might have them , maybe a tutorial on the possible mods to the lt1 is needed.

Any idea when the colored Lt1 will be available? For now just the black?

this is carry case for JBL flip 4, it will fit LT1 too. How many people need it? Maybe a groupbuy?

Now just the black.

It might be something like this:

Basically, some sort of slow leak allowing the LEDs to stay slightly on when they shouldn’t.

Or maybe there’s some GitD powder in the plastic. Not sure; I still don’t have a production model… just a prototype.

Interested.
Four units.

Depending price maybe more.

You can buy those carry cases for like $8 on Amazon.

I found another one has inventory from supplier. LINK to sofirnlight.com

I have one similar for my Tribit speaker. Cost me about $8/£5.

Nice idea as it is, I can’t see a GB benefitting anyone, the postage costs on from the receiver to those wanting a case would be too expensive, not to mention possible postage problems caused by Covid-19.

Nice case Barry! :+1:

Does it continue to glow if you unscrew the battery tube from the head. That should eliminate if it is caused by some sort of an electrical leak causing the glow or something that glows without power.

My LT1s were delivered today. :smiley:

Got my LT1 with Rev 5 board, loving it already!

I got my LT1 yesterday I ordered it on the 19th of last month thru sofirn’s official ebay store

I recieved my D4v2 Ti in sst20 4000k flavor the day before yesterday ordered on the 19th of last month on intl outdoor.

Still awaiting a c8g ordered on the 19th of last month thru sofirn / aliexpress, tracking says it is in shenzen china im sure it is baby trumps doing

Check the thread about the coloured versions:

I have a question... The answer has to be somewhere in the thread, but I can't seem to find it.

The LT1 lantern, by default is configured for 5x7135 (1.8Amps), but can be configured as 6x7135 or 7x7135 (max, ~2.5Amps), by soldering the joint points for each solder point on the driver board. I forgot whether it was also possible to reduce the max power (3x7135 or 4x7135), by desoldering the points marked "5" and "4"?

I notice on the rev 5.0 board, the "5" and "4" appear to be linked by electronic circuit trace.. so it means reducing the power is possible on the older batch but not as easy on the newer batch?

Hey guys does anyone know if the third batch blf lt1 lanterns support type c to type c charging?
