FWIW, any light with more than ~600 lumens should do what you want. But more is definitely better for the blinding effect especially with the flood type beams that I'm suggesting (set it and forget it). An L6 will also give the light shield effect and looks more like a traditional flashlight if that's important. Due to the large reflector and smaller tube it would have a built in up angle to point more directly into the perps eyes.
Prices? Last I knew the Q8 was $80- $100, but you'll need 4 18650 cells. Good cells can be from $5-$10 each. The L6 was ~$60 last I knew and uses larger 26650 cells. It might come with spacers to use 18650s in it, but full runtime will be achieved with the full size cells.
As with all things "tactical", one is none, and two is one. Which means have spares because when the time comes when you really need "it", it will fail, so have back ups. Doesn't matter the brand or quality or the fact that "it" hasn't failed in the past 10 years.
