So this is my understanding, please tell me if it's correct. I graduated in BA and this is like the first time since middle school doing math

-----------------------------------------------------------

Here is my setup:

Tri-Cree Blue Green White

Blue Cree Part# XPEBBL-L1-0000-00301

45.7 Minimum Luminous Flux @ 350mA

Forward Voltage @1000mA = 3.47v

Green Cree Part# XPEBGR-L1-0000-00F01

122 Minimum Luminous Flux @ 350mA

Forward Voltage @1000mA = 3.58v

White Cree Part# XPEBWT-L1-0000-00F51

266 Minimum Luminous Flux @ 1000mA

Forward Voltage @1000mA = 3.15v

-----------------------------------------------------------

Blue:

Step 1: Resitance (ohms) = total voltage / current (amps)

-> R = (3.7-3.47)/1

-> R = 0.23

Step 2: Step 2: P (Watts) = R *( I^2)

-> P = 0.23*(1^2)

-> P = 0.23

Green:

Step 1: Resitance (ohms) = total voltage / current (amps)

-> R = (3.7-3.58)/1

-------------------

-> R = 0.12

===================

Step 2: Step 2: P (Watts) = R *( I^2)

-> P = 0.12*(1^2)

-------------------

-> P = 0.12

===================

And if I to use one resistor for a parallel Blue/Green I can just add their numbers up, am I correct?

R = 0.23 + 0.12 -> 0.35

P = 0.23 + 0.12 -> 0.35

This seems weird...now for the white

White:

Step 1: Resitance (ohms) = total voltage / current (amps)

-> R = (3.7-3.15)/1

-------------------

-> R = 0.55

===================

Step 2: Step 2: P (Watts) = R *( I^2)

-> P = 0.55*(1^2)

-------------------

-> P = 0.55

===================

Please comment on my calculation.
