Why do CSI search a crime scene with torches instead of turning on the lights?
Or is that merely dramatic license?

You can see better with a small directional light than you can with the room flooded with light. When you are looking for prints, stains or other clues, you need to narrow your focus. If you have light everywhere you will get too many reflections on your target object.
