Well, let's figure out first what you want the light for... "tactical" doesn't really say much. I got a Surefire 6P back when they first came out - I was working law enforcement/corrections and needed that kind of light. I've still got it and it puts out 120 lumins or what ever the word is and is blinding bright. That said it has a really short run time. Good for clearing a building, using for 'as needed' shots of light. If you need something else, this won't work.

I think you need to better define what you plan as the primary use for you light and what your expectations are.
