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

I’ve never seen one with a different button.

“T” is for terrific!

Bought 2 within the last 3 weeks. Both got the T button. The spare button have the T also. Never really noticed it and it doesn’t bother me.

Sofirn has a trillion of the T-button caps to use up, so all is good! :smiley:

I don’t think Sofirn has any of the old mcpcb anymore. I didn’t order the one with the power bank function but I got the latest mcpcb based on the chart a few pages back.

Sofirn probably forgot or hasn’t gotten around to fixing the AliExpress store pages

Any guides on how to build a flashing kit for the latest mcpcb?

Not “T” for ToyKeeper? :partying_face:

I received notice today that mine has reached the country, and in the hands of the postal service. Scheduled for Monday delivery, but maybe I’ll get lucky and have a shiny new toy for the weekend.

Big big thanks to you and all who have helped on this project. I watched all your development videos. Long time Coleman gas lanterns user and I still plan on using them as I like the heat from them while winter camping. However the LT1 have become my go to lantern. I use it all the time at work too.

Patiently waiting for the mini version. Thanks again.

Got my third one today in green this time and just love the colour. :sunglasses:

This one has came set with the simple Ui and of course took me few minutes to remember the 10H to switch it to advanced Ui,
these days takes very little to get me confused…. :person_facepalming: :innocent: yes keep laughing you`ll get there one day too :wink: hope not :zipper_mouth_face:

Good that you pointed this out for others.

I’ve bought several different USB-C OTG adapters/cables to be plugged in the BLF LT1v2.0 (or other Sofirn lights that feature powerbank function, eg. the Sofirn Q8 Pro, Wurkkos HD20, Wurkkos TS21, Astrolux EC06, and possibly more in the future) so I can use the flashlight/lantern to charge other stuff that only use a standard USB-A male plug.

I notice that some of the OTG USB-C adapters (male USB-C to female USB-A) have bigger molds that barely fit the USB-C port on the lantern/flashlights.

Side question:

Is it safe to use USB-C OTG adapter/cable (USB-C male to USB-A female) on these flashlight/lantern to serve as a more general-purpose powerbank? Or would there be some concerns to note about?

(I understand some of the cheaper/lower quality adapter/cable will pass a lower current, maybe just 5v/1A; but the more expensive/higher quality OTG adapter can allow 5v/2A or maybe 5v/3A)

I have a massive Coleman GPA collection too! (over 90 lanterns, 70 stoves & heaters. :smiley:

I have noticed a variance in the molded plug end between cords and run into a variety of devices that have problems with inserting the larger molded plug ends.

I switched from smooth ramping to stepped ramping on mine … And never managed to get it back … :person_facepalming:

I think using an adapter is even better than safe (when using high-quality ones) because you can force the LT1 to act as a powerbank and the other device to charge itself. When I plug my smartphone in my Q8 Pro the phone tries to charge the light for some reason, so I need to plug in an adapter to the Q8 Pro which has 5.1k pulldown resistors on the USB-C CC1 and 2 pins to activate 5V.

Yes, this is a ‘universal’ problem with plug ends & sockets on various devices.
I have reverted to shaving a little off the moulded plug to get it to fit a socket. Otherwise I use a different cable.

Turn it on (1 click)… then click 3 times. That goes between smooth and stepped ramping.

thank you for your help;
I tried this already, but 3 clicks does nothing : after the 3 clicks, whether I wait and then hold or turn off, it stays in stepped mode. I must be missing something there

Does your LT1 have Anduril 2? If so, you will need to switch to advanced mode to toggle stepped/smooth ramping.

If you got your lantern recently than just like @Rayoui mentioned first you have to switch to advanced mode to be able to use this future.
To switch to the advanced mode: from off 10 clicks and hold

Damned, you and ToyKeeper saved myself from madness :
I was refering to the cheat sheet on the aliexpress page : Sofin — Lanterne de camping LED multifonction 8 x Samsung LH351D (BLF LT1), lampe ultra lumineuse avec variateur de couleur 2700K 5000K | AliExpress, and it said 6 clicks to go to and from muggle mode … (of at least that’s what I thought it would do)

BUT, after you wrote “Anduril 2” I looked for it, and found http://toykeeper.net/torches/fsm/anduril2/anduril-manual.txt … that says 10 clicks/hold !

so here is what I did :
from Off, 10clicks+hold > advanced mode
switch On, 3 clicks to switch to ramped (and it works this time)
switch Off, then 10 clicks > back to simple mode

Thank you a lot :slight_smile:

… I should have refreshed the page before searching, that was exactly what I was missing :slight_smile:

thx !
