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

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.

Thanks! It sounded appropriate for the vintage lanterns and the madness of over-illumination. The camera auto exposure did very little to show just how overly bright the room was lit.

They are all funā€¦ once youā€™ve learned how to enjoy them without burning your fingers and eyebrows! Kerosene pressurized lanterns are typically of robust design and construction and can burn most flammable light petroleum distillates, but require a portion of the lantern to be preheated before it can be ignited. Its another step added to the lighting process (versus white gas lanterns), but they put out more light and BTUā€™s while burning kero or similar. The vintage versions can be built like tanks, look quite ornate and are collectable. Tint and lux is adjusted by the type of mantles you use (the higher the thorium content, the brighter and whiter), fuel pressure, and fuel type (I mix a cocktail of kero, stoddard solvent and white gas for my kero lanterns). You can usually buy a cheap used white gas lantern locally (such as a Coleman 220) on FB or CL for around $10-20 to experiment with.

Ive seen that pic somewhere too. Very nice! Keep on lanternā€™nin!

Can you please put me down for one.
Thanks.

Please put me down for another lantern, for a total of 3.
Thank you.
