XP-G Cool White at 1200-1300mA
XT-E Royal Blue at 800-900mA Here is the link for reference: http://www.rapidled.com/led-university-1/

which driver are you using?
Mean Well ELN-60-48P ? if Mean Well ELN-60-48P , no need to adjust anything on for the XP-G string For XT-E, you can do from anywhere from 700mA to 900mA. |

Actually cree updated their datasheets, you can run the XT-E up to 1500mA same as the XP-G.
http://www.cree.com/~/media/Files/Cr...g/XLampXTE.pdf DC forward current mA 1500 |

thats 1500mA max but I would think you would want to lower the mA for longevity sake

That's a good level, the most important thing is cooling. If you don't cool the LEDs enough then even at a much lower current than max you can still harm the LEDs, and vice versa.
