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

I’m more of a fan of the 5000K CCT, and in a lantern I guess I would like the 4000K ~ 5000K range, but with variable CCT, I’d be down for much warmer emitters, as long as I still have the option to go to 5000K

2 lights for dmsoule, interest #s 391, 808.

These links are always updated to the latest versions of the lists by the way.

Great update on what’s going to be a great lantern. Please add 2 more for me (#38 on list).

you also have 809 and 810 also, 3 total.

Yeah, that’s me too. In fact, with the variable CCT option, I’d probably want as wide a spectrum as possible. But, then, as FBsLights indicated above, the lantern would “look” better when all lit if the LEDs were closer in CCT. I think 3000k to 5000k will be a good range.

Also, I just found out in the new poll for Your favorite CCT for EDC that Clemence even has 2000k HI CRI emitters available. But he says they’re expensive and not very efficient.

If the light of the leds are blended well, which should be easy with the current design of the lantern, it hardly matters how far the CCT’s of the leds are apart, the spectra just add up to produce a fine intermediate spectrum.

I am on the list for 1 right now. Please put me down for 2 more. A total of 3.

Caseit741, your two additional interest list numbers are 811 and 812, along with 638 for 3 total BLF ultimate lanterns.

Put me down for one. Do we have an estimate of the price?

I assumed I had signed up a couple of years ago, but apparently not. :blush:

Interested in 4, please.

you’re #813 on the interest list. There is no official price estimate. I have been imagining around $40 US, but that’s just my imagination.

You are signed up now for 4 lanterns, interest list numbers 814-817

Going to take my name off the interest list I think. This looks like a great project and I hope it comes to fruition soon, but I don’t want to wait forever, and the prohibitive cost of cells in Canada doesn’t make this practical for me.

Sorry to say you were not on the interest list, in spite of being asked to be put on there.

I started updating the interest list on May 16, with Phlip at interest number 757. I think I have gotten everyone added since that time, about 60 lanterns worth.
Hope there are not too many others that have been left off, but you can always check the list on the links below. They cover everyone since day 1.

Well that all worked out then

Please add me to interested list.

@bmengineer, here are some nice high capacity legit 3000mAh cells for you:

They are legit cells, and they have a valid permit for shipping lithium ion cells, so all is good.

Thanks, but in truth I’m realizing pop can lights are a bit larger than what I need for any practical purpose.

Yeah… probably the main blending question is whether the light can get an even distribution of light with two of each emitter, or if it needs three.

In general, I’d agree. I rarely use anything bigger than 1x18650. But the soda-can form factor may actually make sense for a lantern.

added as #818 on the interest list

I am going to design an eight LED star based on the Q8 four-LED single channel one, but will have eight 3535 pads arranged to offer the best blending of the light tints, and have two channels to control them. ( I have a rough drawing in mind already for that purpose.

As for the other comment I agree that for some cases a tiny single 18650 lantern can work, but the advantage of this Lantern design is much longer run times & output form a lantern that is still small enough to backpack. pushing a lantern past 800+ lumens continuous on a single cell will give barely a night’s worth of run time before it has to be charged. I have many modded lanterns that use a single 18650, but they are somewhat limited to 300 lumens or less to get a night’s worth of run time form a single cell. Thew past test at the camp, the V2 prototype ran on maximum mode for roughly 5 hours per night, and lasted the entire trip without the need for recharging, and when i got home the four 3400mah cells still had 3.83 volts in them.
