So here is what I'm thinking. Depending on your setup, your light is only going to last so long under prolonged use. Now you thinking, "that's why i carry extra batteries." However, flashlights are great for illuminating relatively small areas. What if you are in a situation where you cannot build a fire? Wouldn't it be handy to have a couple quality light sticks in your pack? You'd need to keep them in something to keep them from getting activated.
