COURUI DO1 'Big Head' (Black/GRAY NOW AVAILABLE) $29.99 @ Gearbest ( use coupon: gbcourui) A long-throw modder's light!

Ah, sorry in my rush didn’t see that.
I’d also be interested to know what batteries you guys plan to use in this? I have ordered a nitecore d4 charger but wanted some input on what protected cells to get and from where?
I have read quite a bit so far but it all gets a bit deep… lol.

Where's the gray version?

The first ‘prognosis’ of the gray version was about 10 working days from last week’s announcement, then with the China National Holiday (holiweek?) to start Oct. 1…well, we know the usual effect… Don’t just hold your horses, perhaps let them go back to the barn to rest. Haha

I will keep this thread informed on every pertinent information available. I’m with you with the gray version too, btw.

The first batch of 33 lights will be shipped today.

Well then I must of got lucky and been one of the first ones out, I received my shipping notice around 16:00EST 9/28.

I added a Y3 extension to the order threw customer service so maybe that’s why it went out already.

Edit, can we expect mail to sit during the holiday or will it actually continue to move?

BTW my 3s conversion / totally new buck driver is coming along great, there is a thread about it in the custom mod/DIY section called “buck driver component selection” by tterev3 if you want to watch the progress and see the preliminary spec’s.

Cheerios!

I got a shipping Notification 10 hours ago.

Nice, mine’s on it’s way too.

It all depends on the shipper and its location when the holiday starts. If it is a Chinese company it will definitely sit if it has not left the port. They usually, unless using surface mail, work 10x harder to make up for the lost volume so until they hit the weight barrier they double the efforts.

Hey guys, for anyone who has a courui already, perhaps you’ve seen my thread on the brand new design buck driver I’m making. Anyway I could really use the measurements of the factory driver so I can get to work. Can anyone help me out?

Also if someone has one they don’t mind not using for a few weeks or so I could do an even better job if I had a driver in hand, I would gladly supply you with one of the first ones I get together in return for you sending me yours now.

@Cereal_killer:

I have added the link you posted in the OP. Buck driver design - component selection example

For easier reference to all modders/enthusiasts, the thread below is now added/consolidated in the op:

Teardown and Mod Thread of Courui XML2 Aka “Big Head 3×18650 Side-Switch Thrower” (by LinusHofmann)

:beer:

I feel like venting a little. So, here is a little rant. Feel free to not read it.

I’m tired of getting tracking numbers that don’t track anything. My Courui is marked as shipped and has a tracking number that I paid $1.99 extra to get. I try to track it and it says nothing found. It seems to be the natural state of the world now that tracking numbers are not updated properly or something. I bought an Olight i3s on eBay on the 10th of September. It had a tracking number assigned to it within a couple days. But, not until yesterday did it show any activity at all (Processed through sort facility). Do people not realize that the reason we want tracking numbers is so that we can actually track something? It’s really worse than not having a number at all, because it creates an expectation. Especially, in this case (the Courui), when I paid extra for the privilege of having tracking available.

Tracking shipments has been done for decades, at least by Fed-Ex and UPS. The technology, the processes, everything has been worked out. If they can do it, by now anybody should be able to. There is no reason why a shipping system can’t get tracking right. As for the seller, they are perpetrating fraud when they give a tracking number that is no good. Perhaps they are generating a label, which provides a tracking number, but holding the package and not shipping it. In that case, keep your worthless tracking number until it is worth something - after you’ve actually shipped my items! Until there is something to track, you aren’t doing me any favor by providing a tracking number to me.

Just to be sure, let me clarify something. I’m not ranting about long delivery times. I know that is just the way it is sometimes. I’ve learned to expect long shipping times and be pleasantly surprised when the shipping time isn’t very long. I just can’t understand why “tracking” isn’t consistently tracking anything so many times. It would seem to be so easy to get it right.

Make sure you are using the real tracking number and not just the order number which looks similiar…
There is vacation in china so I guess all our shipments are on one heap for some days before they get tracked.

I used NL post which isn’t trackable but gives shorter delivery times to my country so I can’t check if it is a singular problem

I like to track my shipments, I have the parcels app and it’s quite fun to have an overview which shipment will income next. But I also like the Christmas like surprise packages I have already forgotten about.

It will probably update once it gets in the country

That’s how I do it ;-).

In my experience with tracking numbers I received, regardless of postal service/vendor used (China free shipping), the tracking numbers usually goes active other than “not found” at about 7 to 10 or 12 working days. I’m happy if it goes active after 5 days.

What I don’t know is if your parcel shipped Sept. 29th was able to ‘escape’ the Oct. 1 to 7 China Holidays.

Btw, I almost always use this link to track: http://www.17track.net/en/result/post.shtml

Thanks, tatasal. That has been my experience, too. That’s the part I don’t like. I guess I’d be happier if they didn’t give me a tracking number at all until it goes active “at about 7 to 10 or 12 working days”. But, then I’d still be worried about whether they were ever going to ship it or not. :~

I’m hoping my shipment made it out before the holiday, but since I have a useless tracking number, I can’t know whether it’s moving or not. It would be better if they would assign the tracking number only when they are ready to scan and make it active. That would require that they change the way people are able to print labels at their home or business. The tracking number would have to be assigned only after the shipper had the package in their possession. They’re not going to do that. It’s much easier to generate a tracking number when the label is printed and just make it active at the shipper’s convenience. Especially, when you consider a business with the shipper coming to pick up multiple packages. The label is applied, the tracking number is there, and it can be scanned as received by the shipper before being put on the truck. But, giving away inactive tracking numbers makes lots of bad things possible.

Haha, this is the part that I don’t like either…but as I said, that has been my experience with shippers/tracking numbers that until now I really don’t have an idea how free-shipping, with or w/o tracking, China post works. (but at least parcels with tracking will give you an idea if you are already losing your parcel, haha). All the vendors that I have dealt with before can’t fully-explain how it’s done (as compared perhaps to USPS, etc.) That’s why we always read posts of surprisingly fast shipping AND snail-paced parcels, or something in between, even from the same postal service.

Talk about the consistency of being inconsistent!

Just got my first Courui in today, ordered from KD before I found out about the GearBest deal. Been going through the threads, and can't find any stock output #'s on it, even throw -- weird. So, this is what I got:

On 3 fresh LG HE2's: 2.6A tail (one cell), lumens: 734 @start, 734 @30 secs, throw: 75 kcd (taken at 5 m)

I'm quite impressed by this light stock - not what was implied in the threads. Maybe they changed things? I didn't do anything but apply Nyogel on the threads, and broke the o-ring at the head joint. Plus the e-switch stock driver isn't that bad either - with 2 simple hi-lo modes, and strobe available via long hold. Mine came with a big aluminum 25.8 mm MCPCB that fills the recessed shelf. I would not call the LED centering piece as overly high at 1.80 mm. Maybe they changed it to a lower profile one?

Also amazed of not one little droppage in output in the first 30 secs. There is some intermittent flicker, seen in the lightbox and during throw tests, plus noticed it testing. Not sure of the contact of cells to the driver or what. I'll probably first try dome wire upgrades and simple resistor mod first - maybe a big 31.5mm MaxToch MCPCB...
