Lets try this one on for size:
This looks like a smart, elegant and practical design!
thanks, I can go to bed with a big smile now!
I think this is going to work: XM-size and XP-size leds can be used on the same board without compromising the functionality. Nice!
It may need some fine-tuning (like tilting the therm.pads a bit to make the current path for led #4 a bit wider), make a bit wider clear-outs of the tracing around the holes and the edge, etc.
And perhaps looking at this design people come up with more clever ideas (add XHP70 pads as well :smiling_imp: )
Thanks for the very helpfull drawing and thinking sofar, Texas_Ace, let’s let this brew a little while 
…
Please add me to the list as well.
Thank you!
Ya’ll are too quick lol. I actually noticed the thermo issue just after posting the picture and was hoping to update it before anyone saw it. I had just tossed it out of the way and forgot to position it properly.
I updated the above picture with the pads angled properly.
The entire board will need to be redone by thorfire as I have no exact measurements to go off of plus this is something that would be best to have them do the final design work anyways since I have no idea what software they use and they need to work with the raw source files.
Here is the design with .5mm clearance all around.
Yeah TA this was very fast.
Let’s see what the rest thinks.
Gonna update title and point to this ledboard design to make it easier to see for the rest there is new input.
Welcome to BLF!
and when I do the OP change tomorrow, will update the interest list as well.
Naturally we need to see what the group says, just figured I would knock out the obvious things while I was in there so people and pick apart the not-so-obvious.
Two months ago I have asked for a quote for the Q8 board at a manufacturer based on my hand drawing, and even that was no problem, their engineers just re-did the drawing properly.
So I have confidence that a drawing like yours above should be way sufficient for Thorfire to make a design with all dimensions correct.
Yeah, that was my thinking. Thats why I was not real worried about getting things super exact, just good enough to show them the key details.
Thanks for the additions. Great work everyone on the rework driver. You nailed it!!
TA, it has been said somewhere before, but your contributions to this forum have been great, in a very short time. We all say thanks!
I would like to be added to the list for one light……?
Don’t know about the group, but I give it the big thumbs up :+1:
Cheers David

Welcome to BLF!
Added to the list, this should be updated now.
Title changed with a pointer to the start of the second run for EDboard discussion. Indeed thanks TA for this elegant and rapid design!
Please add me to the interest list, in for one, thanks!
Regarding the clearance of parts and + traces around the screw holes - do you think it’s enough for bigger screw heads which Thorfire might use? Don’t want the problems which Astrolux S41 had.
Screw heads are on the bottonside of the board.
The E14/41 had the board screwed in from above to the housing, this screws from below to the reflector.
Ah, I see …
I didn’t see this anywhere, so I’ll be the one to bring it up, I guess (unless someone else did and I missed it).
Texas_Ace, you said you turned the LED pads so that they had a larger trace size to the ground plane? Do you mean for the LED- trace or the Thermal pad or something else? I can’t see where the copper to the LED- is any bigger in your drawing than it was in djozz’s sketch. And, of course, the Thermal pads are DTP, so no traces are needed there. So, I’m not understanding what you mean by bigger traces to the ground plane.
