Well, the English system, for measuring distances less than an inch is more advanced. The metric system is based on the arbitrary and cumbersome base 10.
Fractional inches on the other hand is based on the negative powers of 2, it’s binary! 
Hmm no. The metric system is the only valid measurement in science worldwide. Imperial units are very imprecise. Its just that you are used to them.
Imperial is better because it sounds cooler than “metric.” Case closed.
Just ordered 40 Copper DTP 20mm XHP70 stars from SinkPAD. They are making a 6V and a 12V version, I got the 6V. Should see em by the end of the week. They’re sending me some DTP Aluminum stars to test against as well as some XHP50 stars.
Very nice lady, Deannae. Easy to talk to, very helpful. Has even been here looking for information, ready to build some lights her own self! 
Will let y’all know when these arrive. I surely don’t need 40 of em!
Would be nice,
if you can send me 5 pieces .
Regards Xandre
Great purchase, Dale, I would not mind 4 of these too :-)
6V copper DTP XHP70 MCPCB’s, oh boy! I think I might like to get my hands on a couple of those guys, Dale. Let me know when your ready. I think I’ve got just the build in mind.
Will do, they’re $2.50 apiece. I had to meet a minimum $75 order which I was told is 40 boards. She’s sending me some aluminum samples as well as Cu/Al samples for the 50.
Now if I can just find the emitters in stock somewhere…
AND, the XHP50’s will be here end of next month. 
Oh well, I’ll have something to play with for a little while anyway. lol
Might have to spend some time pulling my rigged XHP70’s out of lights and putting them on the SinkPAD’s. Then I can test all over again and see if there’s any viable difference with the proper pad.
Anybody seen any real leads to the XHP70/50 leds or copper stars for sale at "regular prices and amounts"? Like 2 or 3 or 4, instead of a bunch? Any word from Hank about his stars or Maxtoch about the 26mm ones?
I haven't been keeping track and probably won't be able to for a long while.
DBC has I believe some MKR stars coming and has them for sale.
RMM stated that he has some bare and mounted to copper on the way.
From Hank at IO?
He didn’t say where they were coming from.
I have 40 SinkPAD XHP70 stars coming, they were supposed to have shipped yesterday…so maybe tomorrow? Cost me $2.50 ea. and that’s what I’ll sell em for.
Richard ordered some of these from SinkPAD as well.
Edit: I’ve been snookered yet again! I was told they had a $75 minimum, “about 40 boards” and I was told they’re $2.50 ea. I never actually did that math!!! I should have 30 coming. I don’t need 30, of course, so will be spreading the majority of them out…
...between the 15 or so lights I am going to build next month. (finished it for ya) 
Sinkpad MCPCBs, LEDs from IO.
I’m aiming for at least 2 or 3 a day, sometimes 4. 
(I’ve done that before, but certainly not on a daily basis)
Can’t afford that many big emitters. Already in a hole, imagine that….
So forgive me but it got lost in the thread, if one put the XHP50 in a 80mm reflector, how far away would the donut disappear?
It’s not so much that you’d see the donut out there in real life, but you’d see a dark central area as compared to a brighter aura. Messes with the brain, as we’re used to seeing a central hot spot.
But it will throw better than a mt-g2?
