I love the low settings for count, more than enough light to see the inmates clearly but not enough to jar them awake so I have to deal with them any more than necessary. lol
Medium and High come in handy when doing area searches or for searching tight corners ect. I don't think I could go back to a just on off light anymore.
Although I do keep one of the Ozark trails in my glove box of my truck and it has served me well.
