Mounted on my Fire Helmet. Doesn't see much use as honestly doesn't see much water abuse. Yet the rear On/Off switch is so stuck that the unit is none functional. Big $ for big problems

great product

For the past 7 years, I've worked in the powerline industry. This light has made it through about half of them. 4AA CPO  has managed to survive ice storms and long nights, and I've even taken it to the river for weekend fun. It's rugged and bright, and the color helps to find it when it's stuck in the mud. When the battery inside blew up a few months ago, I thought it was gone. I filled it with coke cola and let it sit for a few minutes before rinsing it out with water and drying it. It now works like normal. When changing batteries, make sure the bottom spring is aligned properly (to the "one and done" guy that throws them away)
