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

Very cool to find another lantern collector here! We are all lumen junkies, so anything that produces light is fair game. I prefer the early lanterns with the white porcelain treatment under the shade. The white color really does reflect more light and the differences are visually apparent. Its also fun experimenting with different thorium treated mantles and fuel mixtures, especially with the kerosene varieties. I have around 200 lanterns and still growing.

Im looking forward to your LT1 accessory kit. The plastic bowl you demoā€™d will be replicated if all else fails. lol

A little something to heat my house. Dont worry, my insurance company says my house is insured if one blows up!

Itā€™s nice to hear so much enthusiasm from white gas powered lantern owners for the LT1. While I see many advantages for the battery powered version, I imagine the LT1 wonā€™t come close in terms of maximum output capability compared to a gas powered lantern. In my use I donā€™t see that as a problem, but I would be very interested to see a comparison of the LT1 to a gas lantern in a picture like the ones posted above.

EDIT: sorry for my blasphemous comment regarding white gas, I did not realize these are kerosene lanterns . . . :person_facepalming:

Would still be interested to see the comparison though.

Thank you!

I enjoyed your choice of music for the video.
(I have that soundtrack and have watched the movie countless times)

Iā€™ve been gone for a while and see Iā€™m way, way late to the party. But, if Iā€™m not too late, can you please put me down for 1?

Actually, the party is just about to begin. :partying_face: Get your credit card ready.

I seen that video somewhere!

My current collection of gas & oil lanterns is much bigger now, but here is an old photo from a number of years ago:

I did do just that some years ago with the original V1 prototype of the LT1, but will certainly do more comparison videos of the production LT1 to them as soon as they are in production and on the way :+1:

Here is the original V1 prototype, (the lantern on the right of the photo, when it was running 4-7135s on a Nanjg Q-Lite driver) and the Coleman 321 single-mantle gas lantern on the left of the photo, (with two modified LED lanterns in the middle)

I'm sorry to hear that you didn't get a chance to have a look onto the manual in the first place. I asked my contact at Sofirn who created the manual but she wouldn't know. It looks very well done as far as I can assess.

I send you a shared link via PM to download the editable docx-file. It would be fantastic if you were to check the content for any mistakes and let me know about it or maybe even do the corrections (if any) in the file.

I convinced Sofirn this morning to let you check the manual first and do the translation afterwards and not vice versa.

If you see any chance to place the nice logo into the file that'd be great. Otherwise I could also do it including some minor corrections with the layout where necessary.

Thank you Den!

It essentially looks like a copy/paste of the FW3x manual with some edits.

@Lux-Perpetua
I noticed a typo under Temp Ramp configuration (the only section I looked at, btw).
ā€œWhile the lantern is on, clic, click, hold to changeā€¦ā€

Thank you guys. Any feedback is deeply appreciated. I will also wait for Den's feedback.

As far as I know the launch of the LT1 is imminent, so I try to get the translation done asap.

I wonder if the manual was created by some BLF or TLF member.

Also under Integrated Charger on the first section you have ā€œPlease us a premium cableā€ instead of ā€œPlease use a premium cableā€

You know whatā€™s fun about gas/kerosene lantern?

Flame sources have efficiencies of about 1 lumen/watt.

That means to output 800 lumens, you need around 800W of power, while the lantern could do this with about 8W of power, or even less.

I got the manual copy shortly after & looked it over. (sent you a message) Also any typos or errors you see, edit them if you can and send it back to Sofirn.

Please could you put me on the list for one LT1?

Regarding the manual, itā€™s got a snippet in it for thermal config, but does the lantern have a temp sensor? I recall reading somewhere it didnā€™t but I could be mistaken. If not, that whole section could probably be removed.

Just read your PM and replied back. :-D If you say the manual is correct contentwise I'd be more than happy.

I will correct any typos and minor flaws in layout I find and that were reported by helpful BLF members here. Thanks for your support.

Sofirn has (hopefully) given me a due date until the end of next week to get everything straightened out. Not much time this time but it will be done.

Good point! Den / Selene, could you please let me know how to deal with this part of the manual? Thank you.

The LT1 does not have any thermal sensor, as the driver board section is not conducting any heat form the head where the LEDs are. (that section for the thermal sensor can be omitted/removed.
