LEDs and resistors Answered

I notice a lot of people tell you to always put a resistor on an LED. Should I use a resistor if my LED's forward voltage is the same as my power supply?

... but using a resistor will give you a little room for error. . If you're going to be running at max voltage, be prepared to burn out a few LEDs - feces occurs when experimenting. Resistors are cheap.

True, nobody likes darkness emitting diodes... And with cheap LED's there actual specs tend to vary widely.....
