PentagonLight K2 Porcupine Review - Officer.com
A review of the PentagonLight K2 Porcupine flashlight has been posted over at Officer.com. 'The K2 Porcupine, purely as a flashlight, is manufactured out of aerospace grade aluminum and finished with a Military Spec Type III Hard Anodized exterior coating. This is quite common to handheld lights of this type. What's uncommon (to others) is the Pentagon shaped tailcap which prevents the light from rolling if it's laid on a slanted surface. The K2 uses two CR123 3V lithium batteries to produce 70 lumens of light from a Xenon lamp assembly for approximately 60 minutes.
The bezel is a standard 1.25" and the light is 5.5" long overall. Activated by a fairly standard tailcap push button, with practice you can get touch-activation (where the light turns off when you release the pressure) or you can simply click the light on and off with a positive push of the button. The light weighs just over 1/4 pound (about 5 ounces) and has a pocket clip around the body just below the tailcap. I've found the light convenient to carry clipped into my front jeans pocket.'
