If it is to be carried in the pocket - then the IncenDIo is the way to go. It is very small and very narrow for a CR123 light. The SF is a great light but much larger.
Also
- The IncenDio can be set to a medium output and still have a very respectable output. Low output runs a LONG time.
- The IncenDio can use RCR123 cells.
- The IncenDio is less expesive.
- The IncenDio has a cool GITD button and oring.
The SF will be built more solid and project a beam farther. It will probably feel better in the hand when using do to the larger size. Its a Surefire. Just some thing to think about.
I am not familiar with the Lumapower flashlight. I carry a 2-level Cree Surefire E1L in a shirt pocket. It's been the best EDC light I've had so far, and that includes an HDS EDC Basic 42XRGT.
It throws far enough so I can see objects well over 100 feet away at night and I can use it at 45 lumens for hours without the battery running out.
