I now own a 6P, and the U2 ultra in the start to my Surefire collection. I have a friend that can get me Surefires for 10% over cost. I think my next SF will be the M4. I know that it can put out 350 lumens on max, but the most that I have seen so far is the 120 put out by my 6P with replacement bulb. Will the difference between the M4 and the 6P with P61 bulb be dramatic? How about 500 from the 10X???
