Wow great timing Jakesoft! i have been reading about putting in resistors and how to figuring out
the Ohms for them. I understand that now.
But you use the Mosfets to control the RGB LEDs. So the Mosfet is like the resistor, limiting the voltage, but allowing the dimming of the LED's through the Arduino coding.
I am planning on using this RGB star: http://www.ebay.com/itm/1pcs-3W-RGB-LED-3-CHIP-6-Pin-Bead-Lamp-LED-Star-Light-/121149855858?hash=item1c35181872:g:xOgAAOxyYSJR8iHf
With these specs:
Forward Voltage VF (V) : red (min 1.9, typ 2.2, max 3.1),Green/Blue (min 2.8, typ 3.5, max 4.0)
DC Forward Current (mA) : red 385 ,Green/Blue 350
Average Forward Current (mA) : red 350, Green/Blue 350
People are using the Luxeon, and I see them saying 700 to 1,000 mah. So is that the total mah
combined from the 3 LED's Or are the Luxeons more powerful?

Green LXML-PM01 2.55 2.90 3.51 -2.0 to -4.0 10
Blue LXML-PB01 2.55 3.03 3.51 -2.0 to -4.0 10
Red LXML-PD01 2.31 2.90 3.51 -2.0 to -4.0 12
Red LXM2-PD01 1.80 2.10 2.80 -2.0 to -4.0 8
So I guess they are comparable, and the Mosfets you specified above will work fine?
Sorry for the basic electronic questions, I understand the coding better as I have
done BASIC programming.
I have found some nice links today that explained it well for resistors:
