Hi all, I'm considering adding some ocw multichips along with my cree, now when it comes to leccytrickery I'm a complete noob, so my cree chips run at (I think) 3.2v and there's 13 in a string, the multichips are >8v, so do I just add as many to a string as I can to get the same total string v? Then run it from same psu

With the OCWs, I ran 3 of them and treated them as 3 LEDSs each. So that was 9 LEDs on a string driven by a LDD 500H (which is what the manufacturer recommends).
I've attached an image of how I laid out my LEDs. The 5 strings were all whites, all blues, purples, violets, OCWs.
Hope some of this helps

Yeah definitely thank-you @daveH.
I'm actually also considering some warm whites, and once I've finally decided I'll probably ask again for chip placement, lol,
I did notice they were on ldd500. I'll have to get some of those and ldd300 for the violets I already have
