I'm a regular guy. I don't need a high-powered, multi-mode, bullet-proof flashlight to carry around for EDC tasks. What I do need is a little extra illumination from time to time. I wanted a light that was super-compact, super-lightweight, durable, reliable, pretty bright, and stupidly simple (but nicer than a keychain light). All those requirements are fulfilled in the Streamlight Microstream. It's about 1oz, with the battery! It clips to my pocket and is pretty much forgotten about until it's needed. It gives an adequate 20-ish lumens, and is tough enough to survive the occasional drop on the street. I use it to look behind entertainment centers, under desks, inside computers, under car seats, and pretty much everywhere else you can think of where extra illumination comes in handy. It won't drive back a giant angry spider intent on eating a hobbit, but it does what I need it to, and I love it.
