The Streamlight Sidewinder Compact II Military (1451) is a mission-oriented, multi-spectral light built for professionals and advanced users who need flexibility more than raw lumen numbers. Selectable white, red, blue and infrared LEDs cover illumination, map reading, forensic/marker tasks and NVG-compatible operations. The head tilts 185° for precise directional lighting without repositioning the platform. Ruggedized and rated to IPX7, the unit is supplied with an I-Mount and a hook & loop strap to allow true hands-free mounting on helmets, MOLLE or clothing — a practical kit for fieldwork and tactical scenarios.
