Cree base lit

I have used the configurator to obtain a wiring diagram for 3 channel LED Star. Resistor sizes are output for red1.0 , green 0.0 and blue 0.24. Are these values in ohms? Do you really need a .24 ohm resistor for blue? My kits smallest resistor is 1.0 ohm. I was just wondering.

Ohm: yes
Do you need it: no
I do recommend it, but the LED can almost certainly handle the extra voltage, and the proffieboard will use PWM to try to make sure the LED doesn’t overheat.
