I find that they are well made but a one trick pony: pretty much just pencil-beams...that's about it.
I have quite a few Streamlight models. None tosses out a pencil-beam of light. Not even my Streamlight Stylus that runs off of three AAAA batteries. In fact, the light comes with a special sleeve that fits over the bare LED in order to significantly narrow the otherwise floody beam. My first "tactical" light was a Streamlight TL-2 LED model. Functioned very well, if underpowered by today's standards. Narrow beam? No. Not even remotely. Did a very good job of lighting up the sides of small buildings outdoors. The flood setting on my SL Scorpion isn't ideal. Full of dark rings. But, it works as intended. Easily lights up a large, dark, bedroom fully. If you get a pencil-thin beam coming out of Streamlight's HID Litebox, then you definitely received a defective unit. One of those will easily light up a typical house from several feet away. And I mean the entire house.
Streamlight also has their own version of the classic SureFire A2. (At least in function.) Incandescent bulb designed for throw. Along with a cluster of 3 LEDs designed for flood. My Streamlight 4AA Proploymer LED flashlight is specifically designed for flood.
Streamlight makes a huge variety of different lights. I own just a few. None of mine toss out a pencil-thin beam.
