From the size of the light and the AAA battery enclosed in the package, I was expecting the Microstream to perform like a typical keychain light: Handy, but for short-range use only. But when I installed the battery and clicked it on, I realized that this little sucker is bright. The packaging even warns you of eye damage if you stare into the beam! This potent C4 LED bulb is rated for a lengthy 50,000-hour lifespan. The matte black aluminum body is a nice touch, but a little slippery, especially with gloves on. The two-way clip is my favorite feature, as it will clip into a pocket for safe keeping or onto a hat brim for an instant headlamp effect. It also comes with a small keyring attachment and a necklace-style lanyard. All this for the MSRP of $19.95.
