A good hunting light should be able to cast a focused beam as far as you will need to properly engage the animal you’re targeting. Most models vary in the range between 200 and 600 yards but consider you won’t really need to see at half a mile in order to hunt something like a raccoon.
There’s also the peripheral vision to consider for scanning and navigating, and a light that’s too bright can scare certain species off, even if colored green or red. Most hunting lights, regardless of type, can be set to various intensities for the application at hand.
