The test to find the light best for your application is this: stand in a lighted area, or in a dark area with full illumination in between you and the target area, and illuminate into the deepest area into which you will need to see detail.
If you can see detail, things are good.
If not, you either need:
A) a better beam focus or
B) more lumens.
Unless you are dealing with patrol car
overheads and spotlights, I bet your issue will be beam focus. If you work
around patrol cars, you need a properly focused beam AND 1000 Lumens.
