I’m sure others will probably do the same but I’ll definitely be doing a before and after extended run (temp/output(lux) comparison on my 6A nanjg HD2010 (draws 5.84A on a fresh Kinoko IMR 18650). I’m keen to see what real world difference the copper pill actually makes in this host.
I’d like to see not only what run time difference it makes, but how it affects output during that time. The emitter will obviously be staying cooler, longer, so what would the out-the-front numbers look like while the run time test was being conducted? I don’t have measuring equipment to conduct this kind of test or I’d be all up into it my own self! 
Maybe you posted bout this light mod, dunno, if so, do you have a link? Didn't think 5.84A on a stacked up Nanjg was possible in a single cell, at least for a high Vf demand setup with an XM-L2/copper. Copper pill should benefit this setup. I got my vob copper pill measured at 5A using a Powerizer 26650 or SONY 26650. Don't have Kiniko IMR's though - are they less internal resistance than a Samsung 20R?
Edit - ohh, the HKJ review indicates it's the same as a Pana CH. I can't get near 5A, yet alone 6A with a cell that high in resistance (0.08 vs 0.04 for a 20R) - in this thread: https://budgetlightforum.com/t/-/21733, you mention a HD2010 with an XML U2-1C, if so, then yes - can be done...
Like I said, I’m getting 5.3A on a stock unmodded HD2010 with a FourSevens Protected 26650. I haven’t been able to find a single review on this cell. I wonder who the manufactures this cell is.
On the stock East-092 driver with the stock XML/alum, I can see that - yes. Still for a protected cell, that's good. If it's 4000 mAh rated, it may be a KK cell so already has a good low resistance foundation, then if the protection circuit is well designed, you are good there. KP will OEM also, so the FourSevens could just be a KP under their own label.
Yes sorry I should have been more clear. It’s an original XML U2 on copper from led-tech. I have yet to step into doing single cell high output stuff with an XML2 so I wouldn’t know as well as you what’s doable with those emitters.
I’ll also say that I only get this high a sustained current on those kinoko IMR cells, my Trustfire 26650 5000mahs max out at about 5.4 for one and 5.15 for the other older one. They also drop faster from there.
I’m also still using the stock very thin emitter cables that came with the HD2010 so I could probably get closer to the total potential those 16x7135s if I upgraded there. 6A sounds very doable especially on those Samsung 20R
I tested two new fully charged unprotected KK ICR26650 against two Protected FourSevens 26650, and the unprotected KK couldn’t get past 4.9A.
Ohhh - wow, that's an incredible protected cell then. Forgot, I posted this in the other HD2010 copper pill thread:
The 4.9A Nanjg is in the HD 2010 pill now. For the bare pill with a de-domed XM-L2 U2 1A/Noctigon, I measured 5.0A on each of the 2 Powerizers -- not bad. The SONY 50A got 4.95A, MOLI got 4.60A. On a stock HD2010 with the East-092 driver:
SONY 50A 5.6A
Powerizer #1 5.4A
Powerizer #2 5.4A
MOLI 5.3A
Samsung 20R 5.1A
KK ICR 4000 4.7A
KK ICR 4200 4.6A
KK INR 4000 4.55A
The KK's and 20R are the oldest and most used, while the others are newer. All are pretty much fresh, maybe charged in the last week or 2.
I see posts of the good stock hd 2010 having 5amps… Is this okay on aluminum or should some measures be taken?
What's the length of the Protected FourSevens 26650? The only protected cells I've found so far that fit in a 3-cell light are the Trustfire Flames.
I wouldn’t be too happy running 5A on an Aluminium mcpcb, it probably won’t harm the emitter but you’re in the region of the output curve where you actually get lower output with increased current.
So you’ll definitely see lots of benefits going to copper pcb.
If you’re up for it, I would definitely recommend doing an emitter swap to some known emitter tint on a copper sinkpad/noctigon.
Edit: And if you want to do a direct driver swap into the stock pill to get rid of blinkies but retain the pseudo direct drive high mode of the East 092.
This is probably the best option.
You have to use a Nanjg 101 4x and stack 12x 7135s onto the back to get close 6A to an XML. You’ll only get that with the right batteries of course.
The nice thing is it drops right in and the retaining ring still fits, which isn’t the case with the 105c or KD 8x 7135 drivers that have components on both sides of the board.
Frankly I would just get this copper pill and not bother. Stacking chips 4 high is a real pain, it’s seriously annoying to do any more than 2 high |(
Wow I’ve read so many posts talking about stacking, but to see a pic of it… 
That’s crazy-neat. Thanks for the info!
Woah.
I tried a 5 stack and it was a complete fail.
That looks like awesome ‘fun’!

If you’re going to build tall, running a strand of coppper braid vertically for “reinforcement” is essential. Bridging the gap between the pins is much easier that way.
At least that’s the only way I could pull it off, there’s members here who have been stacking for way longer and probably have some better tips
I just use both sides of the board, stack one on top of all 8 on the Qlite driver for a theoretical 6.08A. Just got through doing this with the MT-G2 in my M8 moments ago, with Samsung 20R cells it’s pulling 5.65A at the tail, didn’t even check to see if the cells are topped off. They should be close if they’re not.
That’s some 3000 lumens on Hi, around 1000 on Med, and 400 on Lo. Approximately.
There was a pic of i think a german guy who has stacked like a gazillion high?
The FourSevens 26650 cells are 68mm protected flattops.
How many AMC’s can be stacked into this C8 pill ?
I’m considering 12.
Is there suffice space ?
The original pill can fit an extra layer of AMC7135 chips on the top, so you could have 12 chips in total.
The 3x AMC7135 edition pill can accomodate two extra layers of AMC7135 chips, which allows 16 chips in total.
Here’s some progress that we have made: Eyecandy alert
WOW!
I'm seeing the appeal of copper. :D
