<1>Human's eyes are most sensitive to the Red range of light, but animals are not spooked by a Red LED flashlight, so this red light is very helpful to find the animals in the dark, like hogs, coyotes, fox.are less sensitive to the Red light, so you can find them without disturbing them.
Didn't work out of the box. It's a very inexpensive flashlight made very inexpensively. I bought the bullet and went and bought a coast red flashlight. The good news was I was able to return this one!
