![]() ![]() There is a less common sub-variant of this that adds White LED's to the strip, so it has FIVE pins and uses one for the additional White Ground line. But at any one moment the entire strip wil be one colour, which can be changed later. The controller output header (or the header included in some mobos) manipulates those Ground lines in varuous mixtures to create many colours. All the Reds are connected together to a common Red Ground line, all the Greens similarly, etc. Along a strip are LED's of three colours - Red, Green, Blue. These are a common +12 VDC power supply and three separate Ground lines. The simpler type is often called just plain RGB, and it uses a connector with FOUR pins (and matching holes) in a straight line. (SLIGHT exception below.) I'll talk about RGB lighting "strips", but that applies also to groups of LED's mounted in the frame of a fan, and to other similar lighting devices. They are technically quite different and hence incompatible you cannot mix them in a system. These days there are two common systems used in computer case sfor RGB lighting. ![]()
