Even if it’s the complete light, I think there are BLF members that still want it 
I would buy the light and use it as a host 
: )
I’ve got two myself. EDC at work.
Sold the sinner (apples to orange I know)
Copper Convoy available again

Thanks for the heads up…
Which led do I pick for maximum brightness…?
I have these in XML…would XPL be brighter or punchier?
XPL is a bit stronger. One of the orientation tests.
Was there any reason for the knurling to change from diamond to square? The knurling on the head has changed to 6 fins also.
From personal experience, the Traditional Crush (pressure) knurling is very tough to do on very soft alloy’s like real copper, the soft material starts to build up on the roller blades. Turning and side broaching to produce the square knurling is a tad bit easier…
That graph comparing the XM-L2 to the XP-L is misleading, it uses an old outdated XM-L2 against the highest binned XP-L. If a newer high binned XM-L2 U4 were shown against it the graph wouldn’t show like it does. Just saying.
I don’t know anything about machining so I can’t speak to the reasoning, but I really like the new look. That “grenade grip” is very popular for good reason, and I really dig the cooling fins on the head. Gotta have a new one too I guess…
Of course, you are right. That’s why I wrote to treat it roughly. The author of the question does not give specific diodes. In fact, the author of the question referred to XML and XPL which have successors. Maybe it’s better to ignore this chart.
I have a limited experience crafting with copper, and I can say it definitively started to build up around my cutting bits when chopping a 1mm copper sheet carefully under my vise attached Dremel style multitool. This for sure has to do with its malleability/plasticity with its super high thermal conductivity. I ended up managing fine results, but took careful filing:

I missed the first batch, went ahead and purchased one of these from the second batch, XM-L2 T4-7A
Nice work Barkuti, looks very well done.
Just ordered one with XML2 T6-4C. 7135*8 Biscotti. OP Reflector
I will probably change the driver and maybe the emitter. I thought about ordering a host instead but wanted a light that worked out of the box.
Late to the party… Again.
The 4C with the reflector is kinda meh, but throw in a 20mm TIR lens to blend the beam, and you’ll absolutely love it.
29 days later my Copper S2+ is here. Love at first sight
The package was opened along the way, perhaps by UK customs?
The light arrived in perfect condition and in the configuration I requested. As expected it is a second edition.
Biscotti should tide me over until I get an A6 driver. I wonder if my 42W Weller is going to have trouble melting the solder on the retaining ring. It is ok with an aluminium S2.
Any suggestions? Carclo part number??
If single LED… (no Carclo suggestions for now, but Yajiamei works good)
… if you want a buttery smooth creamy beam, go with these (probably 15 deg is very good; 30, 38, 45 are definitely floody; 85 is extremely floody with almost no hotspot):

… if you want less spill, and more defined hotspot (but not with the ‘artifacts’, which are present with ‘clear’ optics), go with these:

Also, everybody should check, that whether the front lens diameter is at least 20.5mm. Recent S2+ hosts I received, had something like 20.0mm diameter, and with that, the lens gets partially slipped past the green GITD silicone ring, which then results in tilted optics when I fasten the pill.
The new batch of copper S2+ looks different from the previous but I think I like it a bit more. It weighs 170.0g without batteries. I leaving it running on max output measured around 710 lumens to see if it can sustain it indefinitely. At about 10 minutes (didn’t time it) I touched it and it is almost too hot to touch. I guess despite it has the mass, there’s not enough surface area to radiate off the accumulated heat. The lighter aluminum version would heat up much quicker though. I wish there’s a copper light with a lot of heat fins.
This is a 7A tint, which is a very nice warm white matching the copper. No ugly yellow or green in the tint.
The one in my copper S2+ is about 0.802” or 20.36mm. No issues with fit. Unlike my aluminium hosts, the retaining ring was not soldered to the head. phew!
The glass is square with the callipers. Perspective makes it appear otherwise.
