Product OverviewThe Fenix LD15 LED flashlight is the perfect portable AA flashlight in a very small size. Since an AA battery delivers 3 times the electrical volume of a AAA battery, the LD15 offers a brightness beam (max 117 lumens) and much longer runtime (max 39 hours) with Fenix's advanced lighting technology. Furthermore, the design featuring two modes of output, not only provides easy operation, but also strikes a delicate balance between the importance dual requirements of high brightness and extended runtime. If you are looking for a powerful, long running EDC flashlight in the smallest size, LD15 is your perfect companion.Specification LED Type Cree XP-G R4Max Output 117 LumensMax Runtime 39 HoursAdjust Level 1Switch Type Reliable twist switchBattery AA Operation Mode GeneralDimensions 3.14"(L) x 0.65"(D) Weight( oz) 1.74AccessoriesLanyardKey Ring
