…and the gap between the solder pads is smaller so there is more copper directly under the center of the led. (I did not ask specifically for an extra thick copper layer, and have to look up what thickness I actually got)
djozz, it may not be that you got an extra thick copper layer, but that they made that other one cheap, with an extra thin copper layer. 
Edit: What is the weight of each board?
dunno, I can weigh one when I’m home, why do you ask?
Maybe normal is extra thin… :confounded:
I mean, the djozz board versus the generic board. I know the copper core weighs more than the aluminum one. I’m wondering how much difference there is. Just curious.
I like to get one or two but I get no response
Hey djozz I’d like to get two of these.
I would like to get 2pcs of them. Please ship together with the Nichia 219C & 144A.
Thanks!
I’m sorry Lexel, lots of things going on on BLF today, and then there is a life too (work, shopping, making dinner, reading book to my son, comforting him later at night when he wakes up with bad dream).
I will go through my PM’s now.
I wrote you two messages, just give me a price and paypal I add shipping info to paypal transaction
Djozz is very busy lately in part due to the 219C group buy, I am sure he will get to you as soon as possible.
Sorry for the long wait Lexel, finally replied your PM.
(for doing practical work on the hobby I have monday exclusively atm, busy with work, family and St. Nicolaas festivities, just catching up with hobby administration today)
Still have some you’d like to sell?
Yes sure, still have most of them… 
PM’d you.
4 for me, please. PM follows.
I’m in need of a couple. I’ll send a pm
I used these MCPCB’s to test a nichia 229AT today. The results were surprisingly good. It beat out the 219C all the way up to 4.5A when the lack of a thermal pad and DTP caught up with it.
They have the lowest Vf I have seen to date as well!
I take 2 as well to germany
PM me for pricing and paypal
Sent a message also for one board.
