Another thought. I put one of the cheapo 360 lumens light on a Ruger P95, which has a normal 2 white dots on the gun sights. I used that gun for my camping or RV gun while I carried a smaller EDC in the pocket. We have had 2 small dogs for decades and they all have to pee at night while camping. With the 360 lumens, I can see coyotes eyes easily at 100 yards, more important enough light to actually see the 3 dots on the gun and shoot a man sized silhouette at 50 yards or more, so that power level works great for that use. I also have them on my 1911-22 along with laser which I use for shooting skunks at night, lots of them where we live.
However, if I were back in law enforcement I would definitely want one with the 800 or 1,300 lumen burst. The reason is that they are blinding to any one you might confront.
To me, the quality of the light on a pistol is much like the quality of a scope on a deer gun. Everyone has stolen the technology the last few decades, so even the cheap stuff is often very good. If you are hunting deer with a 30-30 and your shots will never be over 150-200 yards any 3 x 9 x 40 rifle scope will do what you need to do. If you are trying to count points on a deer rack at 550 yards in dim light, then that $1,000 scope is probably worth the extra cost. To me, same with lights on handguns. I have a Surelight on my old shotgun and a cheapo on my AR house gun, just does not matter much for me no longer chasing down and arresting people in the dark.
Here's a thought. Buy one of the cheap ones and try it. If you do not like it, just put it on another gun, not much lost.
