This is generally true, and I have given the same advice. But I will note that my fairly new Cygolite 350 (I think it's called the Hypershot?), even with the intensity dialed back a bit, seems to have a shorter battery life than my four-year old Cygolite 150. I suspect it has something to do with the 350's design, which has TWO lights in one enclosure.
