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

I believe they were able to get the 3000K in the numbers they needed fro production, unsure about the 2700K. ( i can check to confirm)

UPDATE -the upgraded test sample has arrived! and i am running it though tests now and will do a video over the next 24 hours on it and my thoughts. So far what i can see its ready to go for production and meets me expectations! Will comment on it in the upcoming video. :+1:

Right on!

Great news! Time for everyone to get their orders in and if you haven’t already done so to check that your name is valid on one of the files linked post #1.

Excellent news, Den!

It’s great to hear that you’re pleased with the latest version so far.

Very much looking forward to your upcoming video! :+1:

Ok everyone, So far i spent the last 7 hours testing, probing, disassembling, comparing, measuring, banging around, and staring at the latest upgraded/revised test sample Barry of Sofirn sent. So far, this is by far the best, most versatile, usable, quality built rechargeable area lantern i have ever seen, built, modified and used. Its a winner! :+1: I will be giving this a green-light for production to begin, all the team has to do is we will finalize the production & specification info over the next couple days. The quality & refinement is much better than the any expensive box-store & consumer lantern i have used or seen. While it may be a bit heavier than the average plastic lantern found in most outdoor stores or online, it looks & feels much better quality and professional. If i were living off the grid or in an area where i depended on a good lantern light with great modes and options, for long-term use in power outages, emergencies, disasters, camping, wilderness cabins, RVs, or even has daily lantern at home, this is it finally. The upgrades & changes i sent to Barry & Sofirn did as requested are spot-on. everything is good in my eyes, and i am giving this final version a thumbs-up for go to production. all they have to do is add the LT1 logo, and create their package options. (as in basic lantern only, and add accessories for other options like adding charge cord, Sofirn high-capacity cells, etc.) I will be doing to the video tomorrow night in my RV trailer with no electricity, only using the LT1 test unit and the original V1 & V2 design prototypes.

Awesome, thanks for the hard work!

Awesome news! Thank you for your hard work and organizing this!

Rock your body ya! :wink:

Awesome news DBSAR! Seems like we are finally close to getting the production started.
Here we go guys!

It is still unclear to me if the warm emitter is 2700K or 3000K? It sounds not much difference but it certainly is a clear difference in practice, both for how warm it feels (important for me personally) and for what intermediate tints are achieved.

And DEN, did you do drop tests? (or was that the “banging around”? :slight_smile: ) In order to gain the classification of “best lantern ever” , surviving mild (toppling over a few times on a hard surface) and even medium drops (a few 1 meter drops on wood) seems very relevant to me.

I’ve been wondering, since neoprene-like covers have been made for other flashlights is it possible to include something similar for the lantern at a later date? Something that wraps around the base, I’m assuming the o-ring bumper on the head should suffice for accidental toppling.

Can it be used as a lightning “system”? For example connect multiple lights to usb charger (power supply) and turn on when there is power over usb and turn off when power is gone? (One switch controlling several lamps.

Maybe even the exact opposite would be useful as an emergency light - when power over usb is lost, turn on.

If it’s not possible ATM, is it possible with firmware update? Can MCU detect whether usb has power?

I don’t know the exact layout of the driver board. But I think there are 2 different and independend circuits. One circuit for the LEDs and one circuit for charging the batteries. Both circuits are connected to the battery of cause.
And I think both circuits can use the switch LEDs for status purpose.

For this behavior you have to change the Side switch. Exchange the switch to a plug and build a remote switch, which you can exchange to a switch-system (one switch and many plugs).

Top Work DBSAR :+1:

New to the forum - Just returned from a camping trip and this looks perfect!
Count me in for 1

A few random thoughts … …

Packaging — As far as I’m concerned wrap and put into a USPS Flat Rate box and ship. I have to remove and re-package for Christmas packages. Now — If this Lantern will be offered on the Retail Market after the Group Buy — I then could see professional packaging — After the Group Buy.

I’m sure some have thought about this question — So I’ll ask … … If one orders on the Group Buy a large quantity — Say 10 or more … … Any further discount ??

As the World is introduced to this Lantern thru exposure from the Family and Friends of the Group Buy participants — Will this Lantern be made available For Sale on the Retail market ??

If upon receipt of the Lantern — We want to order more … … Can we do this at the Group Buy price — And how long will the Group Buy price be offered once the Lantern’s ship ??

If the Lantern passes Den’s series of tests — Release it. Let it get into the hands of the Group Buy individual’s hands as this will expose it to the World. As time goes by — Suggestions will be made as to how to modify and/or improve it — Let this happen to version 2.0 and so on.

I’m down for 5 at this time (1594,1595,1726,1727,1728) — — — Add 2 more for a total of 7 … Unless a discount is offered for 10 or more — — If this is granted ………… I’ll take a total of 10.

It may only require custom firmware. I have an Anduril light that that comes on using a forward switch just fine (once I compiled it with momentary support). So chances are, with some changes, you could not put batteries in it and turn it on and off with USB only. Have to wait and see.

No more changes, SHIP IT!

Thanks Den, and all involved, for all your hard work
