Below are the current counts per person which includes all the ones added through post #5798. Don’t forget to verify that your BLF user name is correct on either of these 2 links ( interest list by entry number or interest list by user name ) in order to insure getting a PM when the buy goes live. Both files pull from the same database table so it’s easier to look at the user name file since it’s sorted alphabetically except for 1 name which has an umlaut in it causing it to sort incorrectly

This is a one-time only check so if you’ve already done so then there’s no need to do it again.

1 lantern = 805
2 lanterns = 330
3 lanterns = 78
4 lanterns = 37
5 lanterns = 8
6 lanterns = 4
7 lanterns = 2
8 lanterns = 3
10 lanterns = 1

Total lanterns = 1959

edited to account for post #5798

My request for 2, a few posts back, seems to have been missed. Please kindly add me?

Thanks

Updates to the lists are published Sunday evening and your additions will show up this coming Sunday.

Thanks!

I have an even “scarier” story that I’ve told here once or twice before. A buddy of mine was helping me work on my truck and I asked him to swap the cells from the Q8 with the ones on the charger, because the light was getting dim. When he came back with it, we tried to turn it on and nothing happened, except the light got quickly warm to the touch. I opened it up, and he had put two cells in correctly, and the other two in reverse, freshly charged!

I let the light cool for a couple minutes, while I told him not too calmly all about the explosion, fire, and deadly gas he could have unleashed on us and my family, who were in the house. But, then I put the cells back in the correct way and we went back to work on the truck. Shaken but not hurt a bit. And these were laptop pulls of unknown age, and not ever “properly” tested even. Modern Li-Ion cells from a good manufacturer can obviously handle more abuse than we give them credit for.

With “modern” fully charged Li-Ion high drain cells I woud rather expect more damage then less.
I was even able to collapse the springs of a flashlight with shorted Eneloops AA (Thrunite TN4A).

Thanks for this answer I made my mind with this

Three please. Looks like a fine lantern.

DBSAR · August 9, 2019, 3:57pm

With all 7 of the 7135 chips enabled, & on the cooler 5000K settings of the tint range its roughly around 800 ~ 900 lumens or more.

Now that is what I’d call the opposite of a shy order.

Yeah, I was only talking about cells doing direct damage to themselves and to other directly connected cells. After the power leaves the cell and enters the springs, the host, the driver, and the emitters, there are lots of things that can happen. I collapsed some springs from “normal use” in a Q8 by only changing the emitters to SST-40 and turning off thermal regulation. Actually, was in the middle of “setting” thermal and didn’t get it “set” in time, so it happened while the light was running in Turbo.

Thank you & the others for the welcome shirnask. I have been watching this develope for a long time now. Finally just couldn’t stand it anymore & figured I bettet get on the train before it left the station.
I think this lantern will work well in our High Country camps.

8,500ft! Where do you go for winter?

cris2pu · August 9, 2019, 11:59pm

Yes thank you

poxin · August 10, 2019, 3:43am

Interested in purchasing 1 when available!

ShyOne · August 10, 2019, 2:27am

When all the hunting seasons have ended in different areas & everything is packed up and secure, I usually go some place warm for a while.
Splitting time between Everglades City FL & Port Eades LA.

Brett · August 10, 2019, 3:28am

Hmmm... now im confused.. Does the lamp come with all 7 of the 7135 chips enabled ?

& will we get a choice of 5000K tint or ??

sbslider · August 10, 2019, 3:33am

Nothing is final, but the talk has been that 4 or 5 channels would be enabled on the production lanterns. If you want to enable more, it will require connecting two solder pads that are very close together. A simple way to do that is to connect them with melted solder. I suspect some clever person will come up with a way to connect them another way without solder. I have some ideas, but I’ll withhold them for now.

Regarding tint, the lantern has two sets of emmiters, one around 5000K, the other around 3000K. You will be able to adjust the tint between only 5000K driven, only 3000K driven, and pretty much everything in between with a mixture of both sets partially driven.

Brett · August 10, 2019, 3:43am

That sounds good, except i wouldn't want to try to change anything on the lamp bcoz im not good at all with electronics & i don't want to stuff anything up on it, but that's great about the tints..

I’ve never used them but they sell electrically conductive epoxies that you can use to attach wires connecting the pads together or maybe even use the epoxy to directly connect the pads.

Personally I would just use solder to connect the pads since it’s not all that difficult to do .

JustTheTip · August 10, 2019, 2:46pm

Please add me for 1 - honestly need a good lantern more than anything else!

yclongthrow · August 10, 2019, 6:19pm

Maybe you should be put in charge.

BlueSwordM · August 10, 2019, 6:32pm

@Brett, it will be coming with 3000k and 5000k LEDs, and you can mix tints to get CCTs from 3000-5000k.
