The new versions seems to out throw the older two. The tint seems to be just a bit higher than the previous ones as well. This one claims to have an output of 3500 lumens on turbo. I have no way to actually measure it but, using them side by side the new version does look to have higher output to my eyes. I like the ramping option, something the other two lack. I think the modes are nicely spaced enough to where I don’t really need to use the ramping that often. So I reckon I like to be able to use the tail cap as a momentary switch, the longer run times with the cell, and the higher output. I know the first batch of new ones had a driver issue of some sort that was keeping it from getting full output. Sofirn was sending out new drivers to those buyers to remedy the situation. I assume I have a already fixed one from the factory as it is brighter thank my other two. I also like the feel of the new light body in my hand. The knurling really helps keep a good grip on it.
