Thanks for all the advice. I like recharchables better than others because I usually have plenty of time to let them charge. However, pjandyho makes a good question. Can you get spare betteries for it in case you don't have time (or a place) to recharge? Also, size is one issue. I lready have a rechargeable tigerlight(minus the pepper spray). I want a smaller light that I can fit in a medium or large pocket. If that means regular batteries then I would take it over a large cumbersome rechargeable.
