I'm preparing to order a PC 2.0 sound card for my lightsaber. I'm running off a 7.4v 1600mA Li-ion battery. The FoC die is a white Rebel (off of a GGW tri-rebel). I'm planning on running it at 700mA (White seems really bright already...but would you recommend 1000ma instead?) So I need the Power extender, wire, and a 6.19 Ohm 3 W resistor? If 1000ma is recommended, which resistor would then be used? The 4.2 Ohm, 4.2 W resistor, right?

Thanks!
