@DBSAR and all the others involved, thank you for mustering together such a useful high tech lantern. Its an incredible effort that’s coming together beyond all practical expectations. Like so many other BLF projects, you really dug in deep to make this one as good as it can be. Your attention to detail is just phenomenal.

Ive been using a Coleman 228 lantern (which has a large hood to reflect light downward) to provide wide area lighting during camping. If no trees are close by my camp, I mounted it to a 12 foot telescopic pole (1/4 × 20 mount). It’ll be interesting to see how the LT1 compares when lifted on the pole or dangling from a tree.

THANKS AGAIN!!!!

Love those classic big-hat 228s! Thumbs Up I have a few of them in my Coleman GPA lantern collection, they can produce some good warm powerful light & heat on cold winter nights when our power goes out. one of the added accessories i been working on & testing is a top reflector to do just that when on a tripod or hanging high in a tree or over head.

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 demo’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!

It’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 won’t come close in terms of maximum output capability compared to a gas powered lantern. In my use I don’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 . . . Facepalm

Would still be interested to see the comparison though.

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 Thumbs Up

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)

Odd i haven't seen that manual yet to check over it.

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.

I noticed a typo under Temp Ramp configuration (the only section I looked at, btw).
“While the lantern is on, clic, click, hold to change…”

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 “Please us a premium cable” instead of “Please use a premium cable”

You know what’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.

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

Just read your PM and replied back. Big Smile 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.

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 fun… once you’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 BTU’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.

@DBSAR

I ran across this work-light and thought the accessories would work well with the LT1. The sharpened threaded aluminum stake is a great idea, and it comes with a tripod base for when it cant be stuck into the ground. Id much prefer to see 2 or 3 2-foot sections, but any height for the lantern above the ground is better than none. Maybe throw something together like this with your shade.

Is the LT1 1/4 × 20 threaded?

Yep, both the side & bottom tripod mount holes are 1/4-20 threads.

TBH, tri-pods and stakes compatible with 1/4-20 threads are super abundant already. I don’t think it’s necessary or even advantageous to pick a specific size/shape/style to sell as an official accessory. The official LT1 accessories should be things like a 180 degree side shade, a top hat shade, and other accessories that are specifically useful for the LT1 and aren’t already available in abundance. This is only my opinion and you’re free to disagree, as always. Innocent

Yep, very true. I am working on a bunch of accessory ideas, and will do a video soon. Thumbs Up
