Okay, this says one LED unit is included, and optionals have to be purchased. However, it says that
four LEDs are needed. I understand the other GN drive requiring a single LED, but how many LEDs have to be actually bought? Where do the other two go? And is it a total of 4 LEDs we're talking about here, or 5?
