Since we want to hook this LED to a circuit board, we will dump the header cable entirely and connect LED light to PCB. We are checking if there is a thru-hole or SMT version of similar header that we can use on the circuit board. Thus asking for anyone familiar with this connector for make and part number.
You should be able to find an appropriate board mountable JST connector from a major supplier like Digikey. However, depending on how often you plan to unhook the LED from the PCB, you still might want to replace the JST connector on the wires going to the LED. For example you could use this connector on the PCB, and this one on the LED wires.
