Who would have thought the LED's could radiate so far?

It's not the LEDs, it's the wires (antennas) connected to the switching power supply for the LEDs. This should come as no surprise to any ham -- switching power supplies are generators of RF trash, that puts RF current on those wires, and like any other antenna, those wires radiate the trash.

Thank you VERY much for posting details of part numbers and vendors for the bad products.
