The UC15 was made in four colors: black, blue, red, and silver. Being so small, it fits on your keychain without weighing you down like other lights. This guy can shoot out up to 1000 lumens using 2 rechargeable 10440 batteries or 250 lumens when using 2 AAA batteries (sold separately), with a maximum beam distance of 107 meters. The UC15's three LEDs are activated with a click of the switch under the head. That's right, three LEDs. In addition to bright white light, you get red and ultraviolet as well!

Regardless of color, this keychain light is made out of aircraft-grade aluminum with a hard-anodized finish. Scratching the UC15 is going to be hard to do on your own. It is also weather- and dust-resistant, meaning taking it out in the rain or on a cruise won't make it stop working, barring dropping it in a lake or the sea for too long.
