There are several common methods out there for powering LED's. Why all the fuss? It boils down to this:1) LED's are very sensitive to the voltage used to power them (ie, the current changes a lot with a small change in voltage)2) The required voltage changes a bit when the power LED driver is put in hot or cold air, and also depending on the color of the LED, and manufacturing details. So there's several common ways that LED's are usually powered, and i'll go over each one in the following st...
