Strmlght Sidewinder X Military W/Mnt
The Streamlight Sidewinder X Military is a compact right-angle flashlight built for operators, military personnel, and tactical shooters who need a hands-free light source without sacrificing output or run time. The 185-degree pivoting head lets you angle the beam exactly where you need it—clipped to gear, mounted on a helmet, or held in your teeth—while the included gear clip keeps it secure and accessible. This isn't a one-trick light: it cycles through white, red, blue, and infrared LEDs, each tuned for specific tasks and adjustable across multiple brightness levels to match your mission demands.
The white LED mode delivers 275 lumens with a 113-meter beam and 3,200 candela intensity—plenty of punch for tactical work without drowning out your night vision in a red or IR setting. Runtime varies based on your power choice: four-plus hours on AA batteries or nearly three hours on CR123A cells, so you can pick your fuel type based on what you're carrying and how long you need to stay in the field. The military-spec construction is purpose-built for rough handling, and the E-Mount base adapts easily to standard gear rails and platforms.
Whether you're running a night op, navigating a dark campsite, or need a backup light that works as hard as you do, the Sidewinder X covers the spectrum—literally. It's the kind of tool that earns its place in your kit because it does multiple jobs well.

Frequently Asked Questions
Can I use this light with standard rails and mounts?
Yes. The Sidewinder X includes an E-Mount base that attaches to standard MIL-STD 1913 (Picatinny) rails on rifles, helmets, and tactical gear. You also get a gear clip for direct attachment to packs, belts, and webbing without rail hardware.
What's the difference between white, red, blue, and infrared modes?
The white LED delivers full-spectrum illumination for general work and navigation; the red and blue LEDs serve specialized tactical and signaling purposes; the infrared mode works with night vision goggles without visible signature. Each operates at multiple brightness levels to suit your needs.
Which battery should I use for the longest runtime?
AA batteries deliver 4.75 hours of runtime on white LED, versus 2.75 hours on CR123A cells. Choose AA if runtime is your priority; CR123A if you prefer a smaller, lighter pack and don't need maximum duration.
