Very nice looking MCPCB’s, looking forward to trying the Q8 with Luxeon V’s or one of my favorite the XM-L2 7A3 CRI90.
@LED4Power, have you thought about doing Nichia 144AM MCPCBs?
I would love a 20mm Nichia 144AM MCPCB.
I think BLF member clemence has those?
No, not a 20mm version yet.
I'm not sure about demand?

Q8 pcb is out of stock until djozz checks if it's ok.
Nice.
Also ordered one reel of Samsung LH351D 4000K 90CRI few days ago, they should be available in ~3 weeks.
Nice ! I will get a good amount of them 
I see in few BLF threads people expressed need for BLF GT XHP70 DTP MCPCB. I can make them,just like BLF Q8 PCB, is there bigger interest(100pcs+)?
If yes,I can make a batch, available in ~1month.
If there is any other interesting MCPCB, I can also consider it.
As seen in his video, (at 1.45 minute) vestureofblood has used a prototype of such a board (with TA logo) in his XHP70.2 GT, the idea I think is that Lumintop at some point will come up with either a XHP70.2 GT or the loose board (and driver). There is no mention of a timeline for when things are happening but the question I guess is if there is a market for two sources for such a board. (perhaps you can contact Texas_Ace about what is going on) .
For me personally I’d be really happy if in a month or so there is a board ready, I have a driver and a led, I’m just waiting for a board now, and I’d be surprised if a Lumintop board will be ready a month from now.
Edit: Btw, I got the Q8 boards and leds in, just waiting for some time to swap them in a Q8 and check the fit and numbers.
My family was gentle on me today and allowed some time to try the led4power Q8 board in a Q8. I posted it in the WDYMT thread. In short, it works fine and the Q8 with Luxeon V leds rocks!
So I’m not up to date on the latest emitters, especially non cree emitters. There may be a better option coming soon. Seemed to be the case as I read some of the previous comments a day or two ago. I’m wondering however, if there would be enough interest in a 16mm board for the OSRAM black flat.
Thanks djozz! That was quick, I sent boards 4 days ago.
I will update Q8 PCB listing today.
I will make 16mm OSRAM mosX gen2 PCB (~4times lower thermal resistance compared to mosX), difference in output compared to copper DTP should be ~1.5 - 2% based on some calculations.
Triple/quad? This is the only powerfull led that may help carclo 10mm optics work the way it was developed for.
I have 3XP mosX, it should be good for testing.

I don't have washers+screws in stock yet, I hope I will have some in a few days.

From now on, shipping calculation is based on weight, over 50€ order registered shipping is available with 2€ discount included. Also, for heavy packages there is Premium packet option available for most EU countries, with good prices.
any idea about the centering rings? which ones should be used? I guess it’s okay with the stock ones but with the hole made a little bigger for the new led
I used a reamer to make the hole in the stock centering rings bigger, it was not fast going because the tiny rings do not provide much grip while the reamer scrapes the inside. Other centering rings that I have in my parts box do not fit the Q8 reflector hole.
