@StephanMatthiesen Yes, that’s correct: they use the magnetic field projected by the AC in the ring coil to induce their own AC in a tiny coil hidden under each LED package— then a precious little group of square-dancing diodes rectifies the current back in to much more respectable DC which lights up the diode. (as much i understand it it so far)

Since this is the case, as you state (and more or less I agree it is correcT)... I dont understand your question. Do you not already know the answer to how many? You count the ones that give off light.... I feel like im misunderstanding the question?
