If you aren't already in the surefire ecosystem go with cloud - SureFire M340DFT-PRO TURBO Series Compact Scout Light Pro Pro Weapon Light

This little light has TONS of throw, but the spill leaves a little to be desired. Because of Arisaka I'm already super invested in the Surefire switch and tailcap ecosystem so this light made sense to me especially since I got it on sale. However, Cloud Defense has near the same throw and much more spill in their REIN 3.0 micro so if you don't have thousands of dollars of SR and UE tailcaps and stupid AXON switches just get a Cloud REIN it's cheaper and better.
