Resistor for Lime Rebel w/NB v2 + 2W bass speaker

[RebelJedi77]

Please excuse my ignorance, but I am finally piecing together my first saber in a while, and I was looking to order the parts to do so today. The only part I am stuck at is what resistor to purchase in a Lime Rebel/NB v2/2W bass speaker/3.7V Li-Ion setup. No additional/accent LEDs, just the Lime Rebel. If I had more time to research it, I would. I have already browsed the forums and was unable to find the answer, so I appreciate any assistance that can be provided!

Thanks, the resistor calc helped, one I Googled the VF of the LED!

Yep, the 1ohm 2W resistor did the trick!10938
