Grouch is correct, CREE has printed the numbers on the COBs several different ways over time.Supra said cxb were printed multiple ways and to match it by the tracing. Or you could check the voltage.
The traces I am referring to are the tiny gold wires you can see through the surface of the COB. The pattern for the CXA3590 is much different than the CXB3590. Your COBs both match the pattern of the CXB3590 and that is a sure method to visually identify them.
Although you may not have a way to test them, the fact remains that they can easily be tested/verified. Therefore Jerry would not have a leg to stand on if he wanted to lie about it and he knows that.
