The TerraLUX TLR-310MR-EX is the one of the world's brightest upgrade kit for Magchargers! Turn your Maglite rechargeable flashlight into an amazing search light that will trump anything in its class. TerraLUX has revised the popular conversion kit design with an improved upgrade. The MiniStar31 now outputs up to 1,000 lumens and has a selector switch so you can choose whether you want it to operate in single mode or multi-mode. Single-mode has typically been the preference of police officers and tactical users that want momentary light with full brightness when they need it. The Multi-mode has traditionally been favored by outdoor users, such as campers and hikers where the lower brightness levels can greatly extend battery life while still giving off suitable levels of light. Now you can choose either mode by using the selector switch on the upgrade. The MiniStar is easy to install; it's as easy as changing a light bulb!
