Compact, yet ultrabright, this flashlight is capable of throwing a beam over 450 ft. on High. It switches quietly among 5 modes: High, Strobe, Nite Lite™, Signal, and SOS. The variable power level helps to conserve power by providing only a necessary amount of light for each application. It also features a motion-controlled strobe rate. Powered by 3 AAA alkaline batteries (included). Battery burn time is 21⁄2 hr. on High, 218 hr. on Low.
