I was skeptical of it being very bright. However, the darn thing is blinding. Now in all fairness, it needs to be bright and blinding to someone looking at it from 6 feet away. This light is easily seen by cagers approaching and it has several different patterns which are good to have. Longevity? Who knows as it is new to me and I will have to see. As to what it is intended to be, bright and noticeable, that it is!
