Hey guys, I have a couple of questions, but since it is late, I will probably not convey what I want to ask correctly (not that I generally succeed any better when awake anyways), but I at least want to start asking. Since I started trying to build my first saber there have been a few ideas that have popped into my head as to possible ways to increase the efficiency of the current led/blade combination. I know this is nothing new, and some of my ideas may have been tried before.

So I'll start off by asking, is there some kind of master list of things that have been tried before, and failed, or conversely succeeded in experimenting with the diffusers, and lens set ups? Examples like, using a solid polycarbonate rod vs the tube, things like that. I have some ideas to try, but I don't want to go over ground previously tread upon, since it would be a waste of effort, hence the question.
