Is there a LED upgrade for the G2Z or Z2 that brings it to over 100 lumens? Right now I have a non-LED 9P, but I'll be moving for college in summer, and it's very likely that I'll get a new SF and leave the 9P here. If that is the case, I want to see if I can get a smaller one like the G2Z or Z2 that will give me more than 100 lumens with a LED (the xenon lamp upgrade is not an option because I don't want to be carrying a box full of batteries every time I plan to use it).
