Mine, as far as I can tell, was lost in Chicago. It says in transit to next facility as it has for the last few days. I’m in Virginia and it never even got close to heading here unless you count the strange occurrence of a Georgia popping up on my tracking shortly after New Jersey

I had a China package spend more than a week in San Francisco customs. Same for Chicago. I think sometimes a package just keeps winding up at the bottom of the pile until they get caught up enough to get to it.

yup, USPS has sorting issues too, LOL

fwiw, tracking says my lights are now at my local post office, and claimed will be delivered tomorrow..
it only took USPS 4 days to move the package a distance of 80 miles within the USA

ordered nov. 12
received dec. 7 in rural NY state (500km from NY city)

I am liking this thing more as I use it. I put a low battery (0.9v) into it 24 hours ago, and got useful light from it all night long. It is still going the same right now.

"Useful light" for me means 0.1 - 0.2 lumens. That means that with dark-adapted eyes, I can use it to navigate around the house, even in completely dark rooms, *and* see the black dog on the black carpet so I don't trip over him. I can stand at one end of a dark room 7 meters long, shine it on the opposite wall, and see all of the objects on the bookshelf. (I could not read the titles, but I could clearly see all of the boundaries, as well as the other, non-book items on the shelves.) It means that I can read in bed and hold the light far enough from the book so that it illuminates the entire page.

Although I did not take it outside, I think it would have allowed me to navigate a woodland path at a careful walking pace. No mountain-biking, x-c skiing, or even trail-running. But it would easily allow you to see the roots and rocks at your feet and for 3 - 5 meters ahead of you.

last night I compared it to my 4/7s Atom0, which claims a low of 0.25 lumens. It was a bit dimmer than that in ceiling-bounce, but also a bit more concentrated.

So that's moonlight mode, and it is still shining on as we speak. I don't want to turn it off, because I want to see what the end voltage is when it shuts off. Then I'll let it recover a bit, and see what its lowest start-up voltage is.

I guess if you have a regulated DC power supply this sort of test is trivial -- you just turn down the power-supply until the light turns off, and then turn it up from zero until it goes on. Anyone want to report results on that?

I can do this but remember that a power supply does not sag with voltage like a cell does. So that is to say that if a light turns on at .7V that doesnt mean that a cell with a voltage of .7V will work.

Okay, got it -- a power-supply is not a good model for an alkaline battery. Well, don't worry about it -- try it out if you get time and have nothing better to do, or skip it and figure that it is not very informative anyhow.

I can tell you that I'm at around hour 32 on a battery that started at 0.9v, and it is still putting out light. But now I would say it is "minimally useful light."

1) I can still read by it, but the light has to be within 12 cms of the page (4" - 5").
2) it is useful for navigation around my house, but I would not want to rely on it in an unfamiliar space. No walking on a woodland path.
(maybe crawling, but then my knees hurt!)
3) the bookshelf test is now down to about 1 meter where I can still make out all the boundaries of the objects.

Comparing it to a ZL H52 on ultra-low modes, it is brighter than the ZL's 0.01 mode, and about equal to its 0.06 mode.

If it was this or no light at all, I would be very happy to have this. But it is really not performing within the range of what I'd say is a functional flashlight.

Still, I'm going to leave it on until it blinks out, to see what the turn-off voltage is. I just hope I don't pop the cell in there -- wouldn't that make me mad!

It didnt start to illuminate until I hit around 0.64 volts

Right. How does that compare to the E01?

Also, I suppose the ending voltage, i.e. when it blinks out, could be lower than that start-up voltage since (as I have heard, but do not really understand), there are some circuits that can continue working on a lower voltage than the voltage needed to start them working. (I assume this has to do with initially charging capacitors?)

excellent question
thanks to everyone for the friendly sharing of information

my C01's are just 2 miles away now.. soon come
I dont plan to use any primaries, my tests will be lumen readings from fully charged Eneloops

stay tuned for the brilliant revelations in which I compare my two C01s to my E01 at Full Power!.. once USPS gets around to delivering them..

I have no idea, I do not have an E01. Likewise it does continue to stay on when the voltage reaches around 0.6V
 
Just like my EA11, 14500s all the way. I have the technology, I can use it. [Bad paraphrase from waaay back when - points for whoever recognizes it]
No, really, I have several charged 14500 cells, a couple of very good Xtar chargers, and if I lose power, a couple of charged up power banks. And if I really have to, a bunch of NiMH as well. Bring it on!
 
Just got my response for the discount.

Ordering later today...I am going to try using a prepaid mastercard to minimize exposure to my personal card.

And after the show jumped the shark, the bionic boy and yes, sadly, a bionic dog.
 
So my order was processed using a prepaid visa card, with no issues. 2x 3200K in black (only color choice), cost/light: $8.71CDN ($6.52USD)


**If anyone is leery about putting their credit card out there this is the way to go. Absolutely no risk on your card getting scammed or exploited.




....and now...the wait.
:popcorn:

In anticipation of someday receiving my lights, I ordered some magnets and B7000 from BangGood. Yesterday I received an email that told me there was no problem with my magnet order but that customs had blocked my B7000. In the follow-up discussion it seemed that they had a list of things that US Customs would not pass. What is there about a small tube of B7000 adhesive that would cause it to be denied entrance into the US?

I just checked and my package has moved from prepared for shipment to passed sorting. At least it is moving.

I used my C01 (finally showed up) to help pull a splinter the size of a redwood out of my thumb. It had been infected for months. Got tired of it and dug it out. Have some interesting pictures but I don’t want to post here haha
