The K1 is one of the smallest AAA flashlight in the world. It is only 2.48" long and weighs .53oz; it's practical and stylish for every-day-carry. The K1 also features the fabulous upgraded carabiner, the S-Biner®, which makes it even easier to carry around. We call the K1 'Small & Strong', as it produces 15 lumens of light which is more than enough for regular activity. The attractive aerospace grade aluminum body with hard-anodized finish, as well as the refined stainless steel head enables you to always have the most functional lighting equipment on hand.
