Summary: Once again, Streamlight delivers, and does it with professionalism and style. If they'd give us the same light but with a tactical momentary switch in the tailcap as well, it'd be nearly perfect. As is, this is my everyday carry light, replacing one that was way more expensive. From a law enforcement point of view, I would carry it was secondary, in a belt pouch.
Pros: LED/Incandescant dual, Compact, Good light output
Cons: No tailcap switch for tactical use, beam less center focused as I would prefer.
Summary: The 2 illumination levels are very useful-- most of the time the dimmer light is more than enough, and using the dimmer light makes the batteries last much longer. But the brighter light is there in the few instances where you need it. The batteries are more expensive and less available than, for instance, AA or AAA batteries, but that's okay, these batteries make for a compact light that gives outstanding service.
Summary: A high quality product, well made. Puts out a lot of light for its compact size. One of the few dual power/dual mode (LED and Xenon) lights available: the best of both worlds (long running time and light output). A great buy for the price.
Summary: The switch has four clicks for a two mode light, 1-xenon on, then 2-led on then 3-xenon on again,. 4-then off. The third should turn the light off. The range is short in my opinion and spotty for both modes. It,s use is for close up..lighting.
