    Hello guys,

    I have a 95W Xitanium LED driver with the ability to adjust the Amp output. I am planning on using x15 Cree XP-G3 LED's with forward voltage @ 2000 mA/ 3.06V (believe the calculations came to 6.12 W per led). The issue that I am attempting to grasp is the LED driver is set at 2750 mA default with no resistor on the RSET.

    How/ what resistor do I wire onto the Rset?
    I attached the driver and led spec sheets and the driver sheet dose have the ohms chart for the Rset to mA values. I have googled this issue and looked through forums but it appears that people have usually used fixed output LED drivers. I appreciate the help, thanks.

    Looks like its a 50k or over resistor for maximum set current of 2.75 A.

    What I am trying to figure out is what resistor to use to bring the amp from 2750 mA down to 2000 mA & how to wire the set up when the Rset on the driver is only a single wire.

    For 2amps use a 6.8k resistor.
