Streamlight Nano Light II Features The Streamlight Nano Light II is purpose-built for everyday carry measuring just 2.2 inches long and weighing only 0.6 ounces so it rides unnoticed on a keychain until it is needed. Its LED emitter produces 20 lumens and 120 candela of output throwing a usable 22-meter beam that is bright enough for close-range tasks like unlocking a door or checking a bag in the dark. The rotating on/off head switch lets the user control the light with a simple twist while the non-rotating snap hook holds the light steady on a keyring during that same motion. Because the switch and hook work independently the light can be turned on and off one-handed without fumbling for a separate button. Construction is 6000 series machined aircraft aluminum with an anodized finish in Blue giving the body durability well beyond typical novelty keychain lights. The LED itself is impervious to shock and rated for a 50 000-hour lifetime so it is built to outlast the single AAAA alkaline battery that powers it for roughly an hour of continuous runtime. An IPX7 waterproof rating to one meter for 30 minutes and documented 2-meter impact resistance mean the light tolerates rain drops and rough handling on a keyring. Every purchase of this Blue C.O.P.S. edition sends a one dollar donation to Concerns of Police Survivors supporting families of law enforcement officers killed in the line of duty.
