What makes a flashlight tactical? If it is of the proper design to be used in a law enforcement, military, home defense, or personal protection scenario. If you are Joe Videogame Dude and don't know the first thing about "tactics" and couldn't fight your way out of a wet paper bag, then you probably have no desire or need for a true tactical light.
I'm ex LEO now. When I started patrol, I was issued an incandescent Magcharger. I thought it was huge and useless, and left it in my car never to be touched. I carried a single incan stinger on my belt, and thought I was hot stuff. Until I dropped it in a scuffle, the bulb blew, and I was now fighting an armed suspect, in almost pitch black, with no working flashlight. It was an eye opening experience.
After that, I added an LED light (Surefire I think) AND carried the Magcharger,for three total lights. I carried two lights during the day,and three lights at night for the rest of my career.
If I was in the game again, I would have at least the following:
1)Full size magcharger or similar style LED light. Perfect for tucking under your arm when taking notes,writing tickets.
2) Two cell Malkoff or Elzetta
3) A moonlight, less than a lumen,navigation light. Needed MANY times while trying to stealthily navigate, and I never had one unfortunately.
4) rechargeable Stinger LED or similar
5) something with strobe. Not really to disorient drunk idiots, but to signal drivers in dark conditions (perhaps at a crash sight) or to flag down the ambulance or helicopter to my location.
To me, a tactical light is uber reliable. That means many Chinese lights are out of the running. A light needed in a dire situation, and you like only have that one single light on you and it needs to work. Or perhaps I should take my own advice, two is one and one is none.
