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

Interested in one.

Put me down for 1 if I am not already on the list

No problem - if there’s one thing I’ve learned through work it’s how to point out missing things on drawings. Let me know if you need help or a more detailed cross-section for Thorfire.

Btw DigiKey has the 2700K and 5000K 90CRI immediately available so not sure why it was mentioned about 6 week lead time.

About $8 for FedEx international priority which is (1-3 days I think)

you have to use the .ca site

add me for another please.

Thank you

I’m interested, please add me.

Has there been any more interest or discussion on the reflector/deflector to allow adjustment or partial blocking of the output from something other than full time 360 degrees?

My thoughts were that it could snap into grooves at the top heatsink and bottom base plate in order to rotate or be quickly removed.

It would not only block light from selected areas of the 360 pie, but reflect blocked light (white front side black back side) back to lighted areas possibly allowing lower settings to be used for more efficiency. Less output and energy would be wasted if directed only to areas where it is needed and not to unwanted areas.

I have made makeshift shields in the past to block light from shining in certain peoples faces or tents and motorhomes with sleeping people etc. For me, having this all available in a well designed manner on this lantern would be the cats meow. There seems to be occasions where I don’t want or need a full 360 degrees of dispersion whether being carried or hung stationary. 180-270 degrees gets the most use from me.

5000K seems on the cold side for a lantern. I’d think 4000K would be better, or perhaps two 3000K + two 4000K LEDs if they mix reasonably well and don’t end up with color casts that shift over angle.

Does anyone else think the profile just feels tall for a lantern? i.e. the tall base/battery compartment combined with a tiny little lantern top above.

I realize this is based off of an existing light to save time, but the aesthetic feels weird to me.

I’d love to see a smaller version - maybe like 1 or 2 18650’s that sit horizontally to reduce height and size.

number 856 on the interest list

only on the interest list once at number 857

Got a third lantern at number 858 on the interest list

you are added at number 859 on the interest list

I would not think that functionally the length is a problem, but of course the general reference being a kerosine lantern, the proportions feel off. I have been looking at it but at least when using the 4 18650 batteries in this orientation, the lantern is bound to be about as tall as the prototype, give or take 1 or 2 cm.

good points. it was mentioned before and can be an accessory possibly to add.

Thanks :slight_smile: definitely a better CAD or cross section for Thorfire would be beneficial.

for using four 18650’s to get the run times including the output which is the main intention of this project, its size is not bad really. the current height works much better for resting on tables than any flatter shorter lanterns i have for illuminating a table top, and its already much smaller & shorter than any other factory lantern i have used that can even match half the output of this lantern.

I am interested in one.

For the rubber seal of the USB:
Utorch UT02 and Manker 22 Manker 21 have round ones which are pretty good. They have two sealing lips and they are better than any rectangular ones I have seen.
Maybe we can get the same type of covers for the charging port?

I understand that some people seriously don’t want 5000K LEDs in their lantern, but I still don’t understand why it’s a problem. If the CCT mixing works right (it should, because TK is writing it) then you can use anything from the bottom (currently 3000K) up to the top, but you don’t HAVE to go to the top! You could STILL use only lower CCT. But, it doesn’t work the other way. If there is no 5000K, then those of us who WOULD use it CAN’T.

DBSAR, this isn’t directed at you. I know you’ve already responded that you don’t have any 5000K emitters to test with. This is just a call-out to those who are adamant that the light should absolutely NOT ship with 5000K emitters installed. I don’t understand why they keep insisting on that.

Can you add a 3 minutes versio of sunset? Or 2,5min on a certain level and then dim to zero?
It is nice when you are in a cold tent in winter time and you zip your sleeping bag

Xiaomi has a desk lamp which does color mixing up to 6500K
It’s for to stay awake.
