I have an L2P that I would like to upgrade from my R5 XPG. I have a Truenite XML single mode drop in on the way. Since my order, I have decided that I want more than the advertised output of 460lm. What ampage controller would I have to get to push this drop in to 600lm? Would this be in the safe range for this drop in? I want it to remain reliable. Where would I get a quality controller? Links please. Thank you very much.
