1. Turn the flashlight on and try to light on objects from distance, you will notice its lighting distance is bad and it's so much unfocused (so much faded edges of the lighted area)
2. Light through walls, while having someone else standing inside the house to verify it lighting though walls
3. Light towards someone who is using NVGs, the other guy will never get blinded...
4. Perform all the previous steps at night when it's completely dark in the game
A quick tutorial on how to make this issue no longer reproducible:
Sit down and fix this up :)
