Thanks for your responses guys.
Seems like the Convoy C8 and the P60 pills are the most popular.
Iām just wondering, are all P60 pills compatible with each other?
I have a P60 pill from FastTech but not sure if itās compatible with other pillsā¦
I donāt see the point of a copper P60 pill unless it is totally redesigned. They donāt really make contact with the flashlight body to dissapate heat. It would have to be designed to eliminate that big ground spring, and fit snugly into the body tube.
Copper P-60 pills are being made, professionally silver plated and with either a center hole for triple board or the more conventional reflector style with 2 holes at the sides.
Contact member mattaus. This is not a new thing for Matt. 
Ouchyfoot, which tube? This is why they donāt fit snugly, theyāre made to be able to fit a wide variety of brands. Make it a bit small and it fits everything, a little too big and it fits nothing.
Cut a 7/8ā wide strip out of the last beer can you tossed. Wrap it in a circle around your pinky, drop it in the tube. Try to put your drop-in inside. Remove and cut short lengths off the strip until the pill fits. Voila! Problem solved.
If you have to shim it with beer cans or copper tape it kind of negates the beauty of a custom copper pill.
Best to stick with a popular light type that the pill threads into the head.
A P60 copper pill would only be worthwhile if it was designed for a specific host. Say an L2P, and exactly fit tightly into that host. Not really worth while. Easier to use a copper star and jam a piece of copper pipe in the body to fit the pill.
Yeah, I hear ya. Mattās are beautiful, but of course that disappears when you cram it into a host. Then itās all about functionality. Someone needs to invent a clear host.
We have some varied expectations, from $2 per pill to $110. 
So I current have these two pills with me, Iāll just ask my local machinist for a quote for both. Iāll just tell him to duplicate them in copper.
Do you guys think itās necessary to have the retaining ring shown in the third pic to be in copper as well?
The retaining ring wouldnāt have to be in copper, but I wish there were one on the HD2010 pill, it would greatly simplify grounding the driver in that one.
The āpillā in my M8 is an external part as well, itās literally the middle section of the light. It has more areaās of threading as the head and battery tube connect directly to it, with o-ring seals, itās finned, so I would expect it to be in the $110 range, itās also larger in diameter so would require a larger piece of expensive copper. I will be having Matt make this one for me when I can get the funds available from my managerās coffer. (The wife)
FWIW, the machine shop down the street took a look at the M8 pill and wanted to take it in to the the guy that programs the CNC machine, said itād probably be over $200 with itās complexity. I think he wanted to program the machine and start selling them! Canāt say as I blame him, as itās a nice part.
What I canāt figure out, is why they spend the extra time and cost machining out the middle of these pills? Why not leave it more solid? Beautiful pill, thin shelf for the star to sit on. Whatās up with that? I put a 1/2ā of copper under it, which helps, but itās nothing compared to the entire pill being made of copper. 
It would be nice if you would make āāc8 pill for 20 mm star
Bore led/star to fit 20mm please.
Why bore the pill for a larger star? Why not use a smaller star and let the pill do the work? Reflow the star to the pill while putting the emitter on the star, itās all one piece, absolute best thermal path. A 16mm star easily does that with no need for that extra 2mm all the way around. My 2 cents.
Hmmā¦ I just measured the diameter of the star placement base and I thought it would be a stretch for the C8 because its outer diameter is already pretty small, but I think it would be possible for the HD2010.
The OD of the HD2010 pill is larger and the star base diameter is already pretty big at about 18mm.
DBCstm, would there be a better thermal path to the pill if there was a greater contact area between the star and the pill?
Don't just copy the HD2010 pill. Allow it to take a 20mm star and 17mm driver, but with enough mass underneath to allow the pill to be bored out to accommodate a 20mm driver. You could ask MRsDNF for the design, then you'd have a pill that's better than what vestureofblood did with his pills, and it'd have more thermal mass too.
Another replacement pill could be for Convoy, especially if there's a pill that's used for multiple popular lights.
Iām no specialist in this stuff, but it seems to me that the heat is going to follow as direct a line as itās allowed to. The tiny emitter base is where itās coming from, if allowed to flow into the pill freely it will have an angle of travel much like the light that flows from the emitter, or a 125Āŗ emission angle. Iāve seen charts that indicated that to be so. Thermal imaging was used to show that heat flows into the heat sink at almost exactly the same conical pattern as the radiance of light out the front.
That is , unless itās bottlenecked, then it has no choice but to mushroom out looking (as it were) for the way out. Given a nice copper pill, with the star soldered to it, the heat is going down before it goes out. So a larger star wonāt see any real heat until the sink starts seeing saturation.
Maybe so, but some of us would still prefer to use a larger star. It's a lot easier to fit a 16mm star in a 20mm hole than the other way around. If I have the choice between a HD2010 pill that doesn't fit a 20mm star and a pill that does like the one vestureofblood made, I'd go with the one that does.
A 16mm copper star in a copper pill is exactly the same as a 20mm copper star in the same size copper pil. A flashligh doesnāt know where the star ends and the pill begins. Itās all copper.
Iād love to help but I never used a standard battery tube with a new pill. My battery tubes were made to suit longer pills. It would not be hard to measure up though.
A bigger star also helps prevent shorts with the reflector when thicker wires are used.
leaftye! The issue of the reflector on the HD2010ās shorting out on the connections is much more easily handled with the larger star. I had forgotten that I enlarged the pill in mine for a 20mm star but then, Iāve done so many things to mine itās hard to remember just exactly where it does stand. lol
Reckon I ought to get a new one and start over.
So whatās the ETA for something like this? Iād order more if there was more lead time.
It doesnāt look like the Convoy pills isnāt practical like I was hoping for by looking at these pictures. That would have been real slick if their lights were modular.

I doubt many, or any, others would be interested, but Iād like copper pills for the A8 clone and F13. I believe both these lights use the same pill.
Anyone know if the Fandyfire HD2010 pill is different to the Ultrafire HD2010?
From the picture ryansoh3 posted above, it looks like the UF takes a larger driver, or at least has a thicker wall for the driver cavity. The topside appears to be the same.
Would you love to help a fellow Aussie, & also keep Aust. Post working, by sending me up one of those copper HD2010 slugs
