Help Sourcing host heads


I was hoping for suggestions for sources of the head components only.
I could buy a complete host but that would be a waste.

I’m looking for the parts as shown in the picture below, something around the 50mm diameter in a flood and 1 flood and 1 thrower somewhere between 80mm to 130mm.
I already have my own driver and i’m using single xhp70’s at the moment.
