To build on some feedback about, how much you looking to spend? And for output, are you looking for flood or throw?
I got some high candela/throw lights in the last year or so. Compared them with high lumen/flood lights and there's a distinct difference. Some YT videos capture much of the difference, but the human eye captures/receives was more. For my uses, my older high lumen lights are just fine. If I were outdoors more, or had a larger property, a high candela light might be preferred.
I currently have Surefire, Cloud Defensive and Arisaka lights. I have Streamlight hand helds, but would be ok with them on a gun.
