This tiny, 2.64-inch LED pocket flashlight with clip-on lanyard is designed for close-quarters use. Its tough Xenoy body is faceted for secure gripping and molded in one piece with the pocket clip so the clip is virtually unbreakable. Pushing the pocket clip activates the switch, which provides quick on/off or momentary activation. A brightwhite light?(9.0 tested lumen value) is produced by four LR 44 1.5V alkaline coin batteries (included). The flashlight weighs just 0.9 ounce with the batteries, which have a burn time of 130 hours. Because impact-resistant Xenoy is a blend of polyester and polycarbonate, it won't cause sparks and is safe to use in electrical environments.
