second what you say about being bright. i use one for caving, and it is much brighter than many external battery pack powered lamps. only downsides are wieght (compared to many led headlamps) and battery life. 1 set of batteries will last about a full day, and it will be many times brighter than most led headlamps. being waterproof is nice too.
