What I meant by tactical was something that could be used on a weapon and/or used by police officers.
That's not always the same thing.
For example, a lot of LEO that expect return fire situations demand that the on/off switch not be ABLE to work other than as momentary, IE: They HAVE TO HOLD it on...if they let go, it goes off...so that if they need to dive for cover, the light will go out, etc.
That also means they HAVE TO HOLD the button in to look around with the light...unless they use a SECOND switch, or twist of the cap, etc, to lock it in the on position...which is VERY inconvenient for patrol, etc....AND makes it even SLOWER to turn it off quickly if need be.
Other LEO prefer a switch that is momentary when partly depressed, but that will click on if pushed further, and off if pushed again. This allows patrolling with it on, and a quick click to extinguish it if things go south, etc.
Almost all LEO prefer a light that goes ON in HIGH, no one wants to have to cycle through brightness levels to get to high...and they want it to not have a memory, IE: If it goes off in low, med, etc, it still comes on in high the next time.
Most patrolling is best served by a floody beam...its hard to sweep an area a few square feet at a time, its safer to see the entire room/warehouse/yard all at once/not give a perp time to dive for cover when he sees the hot spot of your beam sweeping towards him...
Long run times and high lumens covering a wide area mean a larger light to hold batteries that can power that sort of beast. A large one might be club/baton-like to allow DNA sampling of perps in close quarter combat, etc. It mght be heavy and built to shrug off damage.
A weapon light is typically smaller than a patrolling light, as its on a shorter duration/doesn't need the battery life, needs to use common rail mounts, etc (1" diameter range, etc), will tend to be a tight throwing light with little spill (A circle of light on the target, but not a pool of light around that).
If too heavy, it weights the weapon down, and slows response time to bear, increases fatigue/reduces accuracy, etc. So, it tends to be a small, light tight beamed light which is terrible for patrol, but good for aim point illumination.
So, the question is still vague...there are many lights that fill the above requirements for SOME of the scenarios. Other scenarios are mutually exclusive...and you need more than one light to fulfill their needs well.
What scenario, in particular, are you trying to adapt to?
If you are really just fishing for a brand deemed more reliable/tougher, you can just ask that instead.
