I primarily use the Streamlights on long guns. They have a bunch of different intensities and focuses.
The TLR-1 is 300 lumens and is pretty decent (bright) for indoors. I have one of these and a prior version that had a lower output. Outdoors, plan on maybe 40 yards for fast target ID. You can stretch to 100 if speed and best ID is not essential.
The TLR-1HP is 200 lumens, but the beam is focused and I can shoot out to 200 yards on most targets with speed and optimum ID capability. 300+ on targets that have light colors or are reflective is not a problem, but I would not rely on positive ID past that distance. It casts a pretty decent soft glow indoors, but that beam, across room distances is about a foot. This is what I use on my AR when I shoot the night matches, but I have to be able to see a target out to 200 yards right now. The focused beam allows you to look off to the side indoors. I keep the beam at the intersection of the ground/floor and walls if I use it indoors.
The TLR-HL is 600 lumens. It is bright. It is great on a pistol or shotgun outdoors, and a lot of guys use them. For rifle, it does not have enough beam focus out past about 60 yards or so, partly becasue you are dumping so much light up close. Indoors, it is too bright for me.
Not a fan of the "s" versions, and I ended up with one I keep meaning to sell off. I like the toggle they use, and for me it is one of the best. When I shoot and work the night matches, it seems that the people who run the TLR-1 units have less issues than most of the other brands. You can pretty much bet money on the fact that the guys that place at the top of these matches are running Streamlight, Surefire and Crimson Trace.
I have an Inforce, and it is okay, just not enough lumens for an AR and the pressure switch needs some firm pressure.
