How big is the head on that little copper light?
put me down for another set NW with box please!
One set Aluminum, CW please. Serial # 271 if possible. Thanks.
Copied from post #2814
The Cu X5 measures 30.5mm dia at the bezel, 20mm at the battery tube, 108.1mm in length. 46.1mm of that length is the head itself with the weight coming in at 212 grams including a cell.
By comparison, a Sipik Zoomie (clone) is 25.9mm dia bezel, 20.8mm tube, and 91.6mm in length, weighing 83.4 grams with a Sanyo Eneloop.
Edit: Photo comparison. All lights battery tubes are in alignment, as is the Coke can.
Sipik SK68, BLF X5, BLF EE A6, EE X6, BLF Lucky Sun D80, Olight M2X-UT Javelot

dale to me its also in the seasoned version still a visible difference its nto ans issue to me but i thought worth mention it if its possible to make it right it should be done if nto then i got no problem with this little difference.
the colour difference has nothing to do with the machining or factory it comes from its the composition of the material this tube copper is made in a different mix then the block probably different material producers too not machining producers if the material is the same composition it apears same whatever factory it will be machined later
What personal issues Dale, come on. Mr. Admin himself changed the rating to avoid and you say Iâm out of line? For having a screenshot of this very forum as signature? Itâs not like Iâm making stuff up, this is happening right here, as we speak.
You might want to ask confirmation they are using pure copper as claimed long, long ago.
Not to start the religious war about handling leaded alloys again, please. Most wonât handle these much, some will.
For those who do, manufacturing and after, they ought to know the alloy; âtrust but verifyâ because, you know, stuff happens.
i can agree with daniel the ship[ping work its no in gearbest hands but their customer service and offers are not good and trustworthy 4 order 4 issues fake light DOA lights not delivered at all lights not ansering tickets offer 50% refund for 100% loss thats far worse then any other vendor i deal with for me gearbest is dead i would never use them again.
Let's stay on topic please.
+1. Weâre spinning out a bit here. Letâs get back to drooling over this beautiful âlumenous artworkâ in the making.
thank you sir! I have a good friend who is going to love one of those, right next to his prometheus beta v2. He had a cheap zoomie for a year that he really liked until it broke, this will make an excellent replacement...and I get to keep the bigger 18650 version!
Any updates for a release date? should have offered a host only GB, that's all I'm interested in, those guts are getting yanked quick, the lighted tailcaps might remain.
Iâm all for bare hosts too, but Iâm very interested to hear what you plan to replace âthose gutsâ with.
seriously? âThose gutsâ are the best driver in the industry, in many peopleâs opinion, and I choose it over anything else. Iâve got a lot of these in my own lights, with dozens more boards and components waiting for more lights to arrive in the future. It donât get better than this, seems weird to see someone claiming theyâll yank the class-leading driver poste haste. That driver is the same in both the X6 and X5, and fully capable of delivering monster lumens in a quad, triple or single design that is simply setting new standards across the board.
Daniel, a signature line is, by definition, a place to put your signature. Seems simple enough. Not a clothes line for dirty laundry. Those are indeed threads that are listed here in this forum, and if someone wants the skinny on each of those persons grievances, they can find them in the main menu. To list someone elseâs personal grievances against a store with every post you make, and indeed, every post youâve EVER made, seems over the top. That particular store has been very helpful to us here on BLF, hosting more than one group buy and going far over the top to do so. Pretty ungrateful to smear em all over the place that way, and it just really makes you personally look bad for being the kind of person that does that. What if I had a disagreement with you and put in my sig line that YOU suck, for everyone in every thread to see? (Mind you, I have almost 10,000 posts, thatâs a lot of sig lines scattered all over this forum!) In that context Iâm sure you wouldnât care for it in the least. Those threads exist, theyâre out there for anyone interested to look into, why spread it everywhere when itâs not even your issue? Got a personal issue with them? Start your own thread, but why carry someone elseâs torch? (so to speak, forgot Europeans call a flashlight a torch. lol) Thereâs a place for it, and a lot of people donât want to see it plastered in front of em everywhere they look, like so much ugly graffiti. I wonât say anything else either way, will try to overlook it as I have been, but please consider a cleaner more positive sig line for the benefit of the forum.
Banggood is helping us on this group buy in major ways, going way over the top to get it right. Itâs been a hassle, but it always is when trying to get people to see eye to eye when there are language barriers. We have new driver samples being looked at and itâs looking very good, so this particular group buy is well on itâs way in my opinion. Shouldnât be much longer and weâll be seeing a new level of Group Buy in this epic delivery of custom materials and custom drivers and custom tail caps and custom display boxesâŚ. over the top in so many different ways.
A lot of people are trying hard, working hard, to establish new boundaries for our hobby. I, for one, am very grateful for all that is being put into these efforts and I really do appreciate the results weâre seeing.
*B*etter *L*ights *F*orever
Well said, Dale 
I am tremendously grateful for the work done by the organizers for this GB, and I have read through the OP and 2900+ responses. The pics are great, but the information on the drivers of this GB is not exactly clear in this thread. You guys know what it is, but you havenât been at all clear about the driver, from the perspective of someone that hasnât been hanging out with you all very long.
Iâd love to see specific and comprehensive information regarding the driver, just the facts, without insider or trade nicknames and inscrutable initials or abbreviations. If its as simple as âgo look âXâ up,â that is AOK, but for the amount of posts on this thread, seems a major oversight not to discuss this amazing driver into the minutia of its greatness, even if this information is redundant because it exists elsewhere on these forums or wikipedia or wherever. There isnât here.
What I donât know, after reading nearly 3000 posts (iirc, there were about half a dozen posts discussing details somewhere mid-thead, but nothing firm):
What is the true legitimate and proper name for the driver? Who originally designed it and when? What is the running voltage range? Any low-voltage cutoff protection? Is it current controlled, or does it utilize PWM? How many modes? Have runtimes been calculated for the different modes? What is the mode sequence? Have memory?
Iâm happy to know its the greatest driver available and the top choice of flashlight jedi, and its just like the driver in such and such, but that isnât really informative. I donât know what I have signed on for, exactly⌠a couple bright lights no doubts⌠but it is excruciating having to read OT posts about past shipping experiences and ânext time can we do thisâ-type suggestions that have zero to do with this particular GB.
No offense intended. Thanks in advance.

But does it have mtn's guppydrv rev 1? It's a personal choice, the UI is the whole reason I got into modding, being tired of disco modes. I may or may not swap MCU's but either way "those guts" won't go to waste, they will end up in the next light I build for a friend. There's no need to get mad at me for not liking your personal choice of firmware. I know and understand there has been a lot of R&D and TK has put serious love into designing the perfect firmware. I have a little experience with writing scripts, so I have half a clue what it is to tweak it to work *just right*. It's just not my cup of tea, and thanks to guppydrv, I don't have to open up notepad again and work through the hassles of figuring out a new language because all the bases are covered.
the triple -or quad- emitter setup swapped for a single emitter is kinda obvious lol..
The day the perfect light is sold to me is the day I will quit visiting this forum. I'm just here to learn and have fun building lights. I recently discovered how to choose a MOSFET and the differences between types of mosfets, with ambitions towards learning my way around this eagle program I installed the other day. (Mainly for another hobby, the driver tech is more than adequate for me.) I never intend to come off condescending or beligerent so I'm sorry if my words were taken that way. I'm just another new guy with a lot to learn, don't mind me.
Hears whats going to happen. Someone will post a thread so for co-operative buys (sort of team buying) and/or bite the bullet and then go looking for folks to buy the âblack sheepâ of the set (what ever that might be).
The questions are:
Who will start the thread?
What are the most effective ways to split up sets?
When will that thread (not this thread) get started?
Once a âmarket valueâ is determined for both the CU and the SS member (yes I know how that sounds 
) of the set, the exchanges should flow with out a lot of drama.
.02 lumens
AFAIK this is TK's Bistro Firmware (proposed for these lights):
~toykeeper/flashlight-firmware/tiny25 : contents of ToyKeeper/bistro/bistro.txt at revision 208
But I have no other info on the driver.
Hopefully Dale, TK, &/or Krono will enlighten us.
Best Regards,
George
not mad at anybody, itâs your light. Run over it with a tractor and it wouldnât make any difference to me. 
(Hey, have I tried that? HmmmmâŚ.)
For the noobs, this driver is a conglomeration of efforts from members who are on leave as well as current members. It uses a board designed by Wight, with influences by MattAus and several others (sorry, bad memory moment), with a User Interface designed and tweaked by ToyKeeper. It utilizes an MOSFET to run the top end and a single 7135 chip to run the lower 4 levels. This allows PWM to be applied at a scant 350mA instead of the full 5A or so, giving it a very high efficiency in those lower modes. Itâs officially known as an FET+1 driver. ToyKeeper took it a step further and figured out the higher capacity ATTiny25 MCU so more information could be held, then she added mode groups and soft starts and hidden loops and bicycle strobes and a random Police strobe and a digital voltage meter and tweaked the thermal sensors so that it could be manually set to your own taste or turned off. Then Pilotdog68âs lighted tail cap was implemented and that made this light yet more unique.
The original idea of the MOSFET comes from Comfychair, and others, and has come a long way since itâs introduction here on Qliteâs. For a Chinese Manufacturer to implement customer designs is a new and unique situation, an opportunity that hasnât presented itself before, and to use exotic metals takes it a step further. Most here are very well versed in the Noctigon copper Direct Thermal Path mcpcb for emitters. These are produced by Hank at International Outdoor. So there is yet another piece of work in a cooperative effort to bring us the best light we can all manage. [I may be wrong about this, but I believe Hank had these mcpcbâs produced with a new color mask and Alexâs name on them, as well as BLF (Alex is âWightâ) One of the promoters is gonna have to confirm or correct me on this one. The memory thing again. I try.]
Epic, would be a good word to describe this group buy.
I will go out on a limb and state here that I do not like guppydrv and will not use it. In part, for me, itâs too complicated. Mostly because of my horrible memory. My reasons go beyond the firmware itself though, probably best to leave it at that.
I, myself, am excited about this group buy largely for the X5⌠not very long ago we enjoyed AA sized lights that might be able to make 200 lumens, 500 if they didnât fry with an 14500 cell. Right? So imagine my satisfaction in tweaking this little copper X5 into a 3170 lumen behemoth of a light! :bigsmile: Yeah, Epic is a good word.
And the X6 itself is a favorite of mine, with a few variants in my stable reaching in excess of 4000 lumens. They even tweaked the design, threading the reflector so that it is solidly stable and centered and adds itâs mass to the heat sink factor, great work, loving it! This also means that a copper heat sink for a triple or quad build can be cleanly threaded into the head for a very reliable contact and heat transfer. Whatâs not to like?
on both the X5 and the X6?
Just the X6 has a threaded reflector, the X5 uses the Manker T01 Godmes reflector which is a very good reflector.
If you can do a relatively simple spring bypass on each end of the X5 it can do around 1500 lumens from the Efest Purple IMR14500 cell.
Edit: The X5 has a neat square cut section above the emitter shelf, the reflector is heavy duty and has a corresponding flat for good contact. Easy to make a heat sink for.
