Hello, I am new to the saber scene. After testing my first PVC saber today, the resistor I was using had burnt out. I am running the saber off of two Xtar 14500 mAh 3.7v batteries, along with a Royal Blue Luxeon rebel led. The resistor that was in the saber was a 2ohm 1w resistor (Which was clearly the wrong resistor for this setup). So, I was wondering what would be the correct resistor for this setup?
