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

That is not the problem though.

We can get 90CRI LH351D in 5000k.

I actually ordered some. The problem? They are going to take 6 weeks to lead time.

Ditto on that. 3000 to 5000 would keep far more people happy than 3000 to 4000, without losing anything or costing more I suspect. Look at the reports on the Zanflare T1 that have come in recently, thus far there seems to be a preference for the two extremes rather than for a level in between by those who have been playing with them.

check. just a note to VOB, you also are 620 on the interest list for 2 lanterns total

double check, numbers 850 and 851 on the interest list

check for arisdes as number 852 on the interest list

Got it, your second one is number 853 on the interest list

asciiphil you are number 854 on the interest list

junglejim13660 is number 855 on the interest list

interest list sorted by entry number

interest list sorted by user names

All caught up for now.

@Zulumoose, that is easily done. There have already been tests of the 5000k LH351D, so just asking Thorfire to put in 3xLH351D 5000k 90CRI and 3xLH351D 3000k 90CRI is really easy.

The reason we considered only 3000k and 4000k options were because DBSar did not test them.

If i had some LH351 high CRI 5000K LEDs i would test those too. Right now i am testing the 3000K & 4000K because i have these, and modifying the V1 to use four of the 3000K LEDs to be able to do a direct comparison to the 4000K variants while on my trip.

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.
