LED Lenser K3 Keychain Flashlight 880058 is the keychain-ready lighting solution that's a highly convenient, highly compact addition to your glove box, backpack, or pocket. These LED Lenser flashlights make good use of the Blue Moon Focus System, an innovative technology from LED Lenser. Blue Moon Focus separates segments of the white color spectrum from nearby blue wavelengths, then sends the blue tint to the exterior of your beam. The result is an unadulterated, bright light cone bordered by a blue ring that helps define the beam's boundaries and provides a little extra ambient illumination. The LED Lenser K-3 Mini Flash-Light is just over 2.5 inches long and weighs only 1.2 ounces, plus the flashlight is affixed to a key ring for quick keychain mounting. Despite its diminutive size, the K3 still manages to pump out 15 lumens of light, plenty for close range illumination of your car, bedroom, or anywhere else. The perfect mini flashlight for constant carry, choose the LED Lenser K 3 15 Lumen Flashlight for its compact size, bright light, and ease of use.
