I have read that the flashlight can be regarded as "tactical" when it possesses the output that can temporarily blind an agresor whose vision is adapted to the dark. Flashlights outputting 80 lumens (sometimes determined borderline) and more can do this and therefore can be regarded as "tactical".

I have experience with the Fenix L1T V2.0. Itīs very good light. My only critique is that it has no clip and its surface is too smooth so the flashlight has tendency to slip. But as for the TK10/TK11 this is not the case (judging from pictures).
