Alright, thank you so much, that helps out a lot!

So I should have 2, .47ohm .5w resistor and 1, 1.2ohm 3w resistor, correct?

I need some help calculating resistors. I plan on using this LED and this battery. I got Green-0.2, Red-1.2 and blue I got 0.3. How do I use those values to come up with the resistor I want? Please...

Ok so for the others I got Green-0.2, Red-1.2 and blue I got 0.3. How do I use those values to come up with the resistor I want?

Edit- I figured it out, it should be 2, .47ohm .5w resistors and 1,...

Thank you I'm glad that will work. I'm having a horrible time coming up with the resistor calculations, can you help?

What I got (which is probably wrong):
LED 1 - 0.035
LED 2 - 0.325
LED 3 -...

Will I have enough power for this led with a 3.7v battery?
