Thats excellent, the difference between Milspec and standard in Red and blue is quite pronounced. That is a very extensive and useful set of comparison beamshots, well done! :D

Dude, you rule. Awesome beamshot pictures. I haven't been terribly interested in the Kroma (another TIR SF? *Yawn*), but I can see that the Kroma actually has usable side spill to go along with the focused TIR beam. I'd personally rather see a UV/Red version rather than IR or blue, but my interest is finally piqued.

Am I the only one that loves their U2 (pending my lux & runtime measurements this week) even more after seeing the beamshot comparisons?

Edit: NoFair, you beat me to the punch!!

Wow, curse, you really did it up here and I sincerely thank you. I was having a hard time making a decision on Kroma vs Kroma MilSpec vs U2 and you have 110% answered all my concerns.

Huge thanks again for the time and effort to put this detailed comparo together.
