I've read the review on the 10X, and it sounds like it would be as bright as the M6. I also read that rechargeables are never as bright as their battery powered brothers. If I get a 10X, will it be as bright as a M6?
Comparing my 9AN to my M2 (w/ P61), the 9AN is a little brighter (140 lumens) than the M2 (120 lumens), but the color isn't as bright (where the 9AN is a yellowish color as opposed to the M2's white color).
