I think you need to go with the newer breed of flashlights. The Surefire is yesterdays light. You need a light that will strobe and pump out 600 lumens at the min.

When you got twice the power and strobe then that will bedazzle the target. In fact, my 1xAA flashlight with the Cree R5 has as much power as that surefire in your hand.
