    Default Urgent electical help please!

    LUX 1 Royal blue LED

    Source power 6v

    using the handy calculator I need a 8.2 ohm 2w resistor, which is pretty much impossible to find locally so my question

    can I gang up resistors to get what I need?
    If I gang them, I cant match OHM, only Watt
    How much does the OHM matter?

    Radio Shack sells a 8 ohm, 20w resistor will this work?

    Some one help please!

    IIRC wattage doesn't make a much of a difference, but that conversation with J-Lo was a loooooong time ago.

    soo I can use the bigger resistor, and the OHM is the important part

    Yes. It's ok to go over the wattage that you need, but not under.

    8 ohms is close enough for this.

    And why are you using 6V for a Lux I? What color is it?

    And, why am I not re-reading his original post to see if he posted what color LED he's using?
