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

Interested in two please.

Put me on the list for one please.

Nice to see some progress! But what happend with the tint ramping option we discussed earlier? As far as I understood it, we would need at least 6 LEDs (and a new LED board) to make that work.
Also I thought that our priority is to create the “ultimate Latern”, not the cheapest.
And please add me for a second one.

I would be interested in this, please add me to the list.

Definitely interested. Those Samsung LEDs look really nice.

Is it intended that the lantern is water resistant? The schematic shows an o-ring at the base of the diffuser, but nothing at the top or around the center screw

The cup shape makes it much stronger than just a cylinder type shade. i did test that shint base reflector idea originally, and the flat-white surface increases light reflection and reduces the hard-light glare and bad light distribution flaws of most factory lanterns i tested & used. (shiny or chromed reflectors cause to much glare & artifacts.

The cross section can;t really show it, but the shade would definitely need either one or two index locking notches at the head area to lock it from turning. (Same goes for the base)

added! number 849 on the list.

That tint ramping is definitely in line to be added, as this cross section is just the design of this prototype being tested. All it would need is the change to six emitters, ( three 3000K & three 4000K LEDs) and the addition of a third wire lead from the driver.

Thanks for mentioning that to remind me i missed adding that to the drawing. :smiley: i did forget to add the upper rubber gasket/o-ring to the head & the small o-ring to the center bolt. (next updated drawing will have those)

Could you please put me on the list for one light.

Thank You

This really is coming along nicely :+1:

Is the tint range finalised at 3000K to 4000K?

I was rather hoping for 3000K to 5000K, because that would cover everything I ever do with artificial light, from reading at night to workshop stuff, respectively.

I understand that LEDs aren’t always available with high CRI at the cooler colour temperatures, though, so no worries if that’s the case. High CRI is more important to me here :slight_smile:

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
