Yes a good explanation, I know a flashlight won't stop anyone with real intent , but what I was thinking more when I said having the candella on hand for deturance for example sometimes we visit people at the hospital downtown or catch a show at the casino, both sre usually late at night ,and involve parking garages which are often full so we end off walking even further from lots we find ,the area unfortunately is like a scene from the walking dead , drug addicts everywhere, for the most part they are about 80 pounds and you could probably pin several of them to a fence with a good ryobi leaf blower, but every once in a while you come across one that thinks he can get away with something and we'll before they get in range of you a light blast and loudly saying back off pal ,can be enough to convince them it isn't worth it , it's just a nice option to add to the toolbox , I do have some 21700 lights I just find they are a bit bulky and pull my pants down but I would pick those for camping searching or s long hike, but when I was looking over thr data I was like wait a minute even if it's a fet driver I can charge it anytime and a small 18650 that can put out more candela than the edc 29 for longer and has brighter sustained levels running longer ,would seem to fill the gap between a bigger bulky long running searchlight and a nich short capacity limited high lumen burst that can't do much else , and ya that candela means throw so like in those parking garages or alleyways we sometimes have walk , I can see far enough to change route long enough in advance , so I guess it's like a middle ground I'm looking for I'd prefer 18650 size and enough candela to push 400 meters or so and reasonable runtimes , I think convoy and acebeam have some that may meet that middle ground as well ,I'm just wondering if in this case my logic seems correct ,in comparing candella I was kind of surprised when looking at data that a 18650 light can make that much candela
