Another example of a rechargeable duty light is Insight Tech-Gear's H2X Arcturus. Its Dura-Last LEDs produce a maximum output of 150 lumens controlled by a multi-function tail cap that gives you constant, bright, strobe, or S.O.S. light modes. Built tough, the Arcturus is waterproof to 15 feet and made with lightweight aerospace anodized aluminum. Runtime is approximately three hours on a full charge. The charge will last for a full 12-hour night shift. The Arcturus is easy to use with a handgun, no matter which light technique you choose. The flat of the light mates up well with the grip of various handguns using the Rogers method. This flat gives you a nearly perfect two-handed grip-something fully round flashlights can't claim.
