Rechargeable / Dischargeable Search And Rescue Flashlight Good Heat Dissipation

You will be marveLED at its excellent high reliability & durability and will find the design is workable for a 2+ pound light. The case is made of high strength aerospace aluminum alloy construction with anti-scratching type HAIII military grade hard-anodized finish, and the texture on the exterior of the light is handy for holding with cold/sweaty hands or even if you are wearing gloves. It is also waterproof in accordance with IPX-8 (submersible to 2 meters).

Thanks to the Direct Thermal Path Copper MCPCB(which improve heat dissipation effectively to extend the longevity of LED), consistent silo integrated structure and the ample heat dissipation fins, SD75 has the best heat dissipation at its super brightness.
