yes we have 140mm x 70mm, pin fins, does that work for you

Hey, thanks for the reply. I think the heatsinks I'll need will have to be larger than that as I will run these lights at 2100mA, giving each one about 109w of power. I'm looking around still and checking in with people, but I believe if its to be a passive pin heatsink will have to be around 180mm?
