LMAO... leave it to China to name one of their flashlights "Old, Long, Cheap"! Next they'll offer a disposable model called "Who Flung Poo". While some of those "tacticle" lights look the part, they are far from what manufacturers like Streamlight, SureFire, Maglite, etc. produce.
I own more flashlights in various sizes, lamp types, etc. than some members here stockpile electronic components. There are varying qualities of xenon, halogen, and krypton bulbs with some of them producing not much more output than a standard lamp. The same goes for "ultra-bright" leds. Reflector and lense design and quality is also a very important factor. I have a "shake light" that is pretty decent IMHO. I also have a dynamo powered incandescent flashlight that also works rather well. But there is no other favorite of mine other than my Luxeon and Nichia LED flashlights. I always take extra effort to know where those are lying about and always reach for them as first choice. The Streamlight is a quality product that could withstand any environment on this planet short of being tossed into an active volcano.
