, no fear of walking the dog late in coyote territory. Only drawbacks I find are the cr-123 batteries which do not come cheap and second, they do not last as long as the manufacture claims. I must submit that I have never officially timed the battery life empirically, but after years of using a wide array of different lamps intrinsically I intuitively sense this to be the case.
The lith batteries may be experiencing performance degradation due to storage or exposure to cold that limits their effective life.
