    I bought some LEDs and im not really good on what resistor i should use. I have the specs of the leds below

    Technical Spec
    Source Material: InGaN
    Emitting Colour: Blue
    Emitting Wavelength (nm): 465-470
    Size: 5mm
    Intensity (mcd): 6000-8000
    Viewing Angle (deg): 20
    Forward Voltage (mA): 3.0-3.2
    Forward Current (V): 20-30

    I want to connect them to the 5V source from the 360 HDD and I was just wondering what resistors i should use. Would and 82 Ohm be ok? or 100ohm or am I completely off?
