for the Convoy Nichia LED I would strongly advise to make a resistor parallel to the LED which eats up 200mA
R=U/I=3.8V/0,2A=19 Ohms
P=U*1=3.8V*0.2A=0.76W
mine on this star is dying, lost about half its output
I used that light more than 20 minutes continously some times and its not good at 700mA
Hate to revive an old thread… but anyone know where i can find a few of these boards for the Nichia 119? I have a couple dozen 119’s that i have a project form, but no boards to put them on.

Yes, the VirEnce VR16S1 board will fit the 119’s fine, but are a bit overkill at 4 dollar per board.
The boards from the OP were not cheap either and are unfortunately sold out, I had 200 of them made and sold most of them and have only a few leftover for own use. And it seems that you need many. I see no source for 119 boards on the internet atm
So sorry, that USD 4/pc is there for unlucky reasons. For anything below 10 watt it’s overkill. Any cheap non DTP board will do just fine. Try Digikey or Mouser.

Any cheap source for get them or similar at 1~2$ Piece, better if free shipping? need some
I’m behind in sending out stuff at the moment, and next week I’m away for work, so it will be next weekend before I will send the next boards.

If you still have some to sell i will take 3 Boards.
Yes I do, 3 boards is fine, and thanks for the PM. I will reply this weekend because I’m not at home atm.
In general, I have so little boards leftover that at this point I stop the sale. Will update the OP and title.

These would be a nice addition to Clemenece’s new online shop I think.

Portable Thrower Comparison
Clemence has a version in the pipeline if I’m correct that should perform better than this board.

I think the clemence PCB’s will work with the 119. I would contact him.

You should buy S2+ UV Nichia 276A very early, I changed the aluminum plate to copper plate for several years.
