[SOLVED] RGB case fan single ring or dual ring?

[theheadshotdude]

So, I found 2 case fan kits, and one is single ring and the other is dual ring, that is the only difference between the two. But, I have no idea what it means? Can someone elaborate pls?

Single ring = 1 ring of LEDs on one side of the fan

Double ring = 2 rings of LEDs, one on each side of the fan
