Subtract the LED voltage (around 2 volts) from the power supply voltage and divide by the current you want. This is the resistor value to use. This is Ohm’s law.

Some are in kit form others are ready built. Hook up a power source, a set it to the highest resistance hook up a load and dial down the resistance until you reach an acceptable brightness.
