"All the lumens?" with John Chapman

This Article was published by Mr. Chapman in a private training forum. With his permission, I share it here for others. -Whiskey Delta Gulf

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.
