Very bright...consumes batteries within 2 - 3 weeks of daily hunting...but still works, just not a bright.
Great light. It does use up the batteries pretty quickly. One of my more important weapons in my scorpion hunting aresenal....I get them with duct tape on a ruler, than i put them in a shopping bag and generously give them the coup de grace. I do NOT recommend hitting them with a hammar (lazy move i did) -- sprayed juice and maybe their venom nearly into the eye.
