At first this might seem like common sense - obviously a flashlight would illuminate a dark space,.. but what the public doesn’t understand is the importance of adopting the mindset of ‘all dark holes contain threats’.
A 700+ Lumen light will allow you to perceive threats at a safe distance, to be fully aware, and be alert of your surroundings.
Always ‘clear’ an area! Whether your taking walks at night, walking the dog during dusk, or hearing a strange noise in the house. Always make sure to 'CLEAR' an area before proceeding. Clearing an area will increase your chance of safety and unknowingly walk into an ambush.
