I bought a bunch for people for predator hunting and they work great!!I would rate them as brighter than any headlight I have seen.They are either red or green emitting color.I have 2 or 3 left of each color but they are going fast.Each light will come with a charger,2 batteries,pressure tail switch( for use on a gun) and a mount to attach it to a scope.I can see a coyotes eyes at 400 yards on a clear night and can easily shoot a coyote at 250 with this light.First come first serve.There are a few peeps here that have them and I am sure they will chime in to how bright they are.60 dollars for a light kit.(one light,2 batteries,charger,tail switch and a scope mount)Small and lightweight and I will show anyone before they buy how bright they are.The lights are a gunmetal grey and not black light the one pictured
