Just found this :- http://www.intl-outdoor.com/cree-xml-u2-1a-16mm-copper-mcpcb-with-brass-cap-p-403.html
The specs don’t seem to say, but would it be fair to assume this fits in a 20mm pill? What’s people’s opinion?
It will go into a 20mm but it appears to be made for a 16mm pill.
These seem to have been sold out for a couple of weeks now, I keep checking back in the hope that they’ve got a new batch in…….

Johnnymac, I agree on the board size, but if the boards 16mm, in a 20mm pill, that leaves 2mm for wall.
It doesn’t look like a 12mm star, hence my question. :bigsmile:
Woody, I’d not noticed the stock level, just found them and took an interest as I have a 20mm pill that needs an emitter and driver…
Thats what I found.. also available for XML. MOQ is too high for me tho.
I don’t think I’ve seem a 17mm pill specified, it would make either the wall .5mm or its description is wrong. :~
Be sure to take note of this thread which shows those Int'l Outdoor pcb's are not copper anymore. (Unless this is a newer version and it's changed again.)

If you look on his site at the p60 drop-in he sells, you will see that they use a 16mm mcpcb and these brass emitter caps. Whether they will fit any generic p60 pill remains to be seen. Appears to be a little on the gimicky side to me anyway.

Hmmm, I’ll have to come back to that link, I agree possibly gimmicky though, just it may have worked in my c8 pill. P60’s aren’t a consideration, I don’t own any and don’t plan to. 
My other thought is that if your soldering is not up to scratch, it would make for an interesting time…. And, will a reflector seat properly?
Exactly! It looks like a recipe for a short circuit at the LED to me.
Yeah, unless there is an insulator on the bottom this is a horrible idea.
I shouldn’t click on links….I now have a 1/2 26650 lxp sat in my cart. 
I tried placing an order for XPG copper MCPCBs from that seller in early September, but got a reply saying that they were out of stock and are not going to produce it anymore 
Seems like it would also interfere with the focus of the led, pushing it down out of the reflector.
