Mine had 2 ohms series resistor. I dropped it to 0.82 ohms, if I remember correctly. And, of course since mine was green, I put a Q3J emitter on the original star pcb. I think I'm going to use a ZLT booster either with a dummy AA, or if one of my buddies can match the threads, I'll have it cut down to 2AA size. The light is just too long!
