hey all, I have an older surefire 6p that I just don't use, since my fenix little AA light is near as bright and much smaller. I've recently read that there are some drop in LED kits that make a 6p really great (as in 300+ lumens). what's the best way to do this? The Malkoff kit I looked at is like $40, which seems like a lot to spend on an older light. any other options and is this project even worth doing? I would happily put the 6p back bedside or on a rifle.
