    Hello
    My circuit 6led series 800mA x 3parallel (1A max P4 Seoul) PSU:constant current 24Vdc 2.5A. To each series add R2.2ohm seemed very big, any other idea? http://led.linear1.org/led.wiz
    Please help if I want a circuit for over current protection ?
    thank you

    PSU:constant current 24Vdc 2.5A.
    does not compute...

    2.2 sounds right but you didn't specify the forward voltage drop of the LED, so it is rather hard to double check it.
