So, I did some initial testing today and first tried a ferrite core roughly where the wires leave the main board. Here, I found no discernable change.

However, without splicing the wires (yet) I placed cores between the main board and each LED unit (the white bed light LED units) and achieved a significant improvement in performance. I'm not a rocket surgeon, so I'll estimate a 82.71% improvement. In this scenario, I just barely have the pairs of wire pulled into the core center since there is not enough give to pull them through fully. In other words, it is jury-rigged at the moment, though with good results. I suspect, once I splice the wires and fully pass them through the ferrite core, I will achieve a great result.

More to come, when I find some more time...
