The Streamlight Sidewinder Stalk is a versatile, hands-free lighting solution engineered for professionals who require adaptable illumination in dynamic environments. Featuring a flexible, articulating stalk, it allows users to precisely direct light exactly where it's needed—making it ideal for helmet-mounted use, gear attachment, and close-up task work in low-light conditions. Designed for maximum operational flexibility, the Sidewinder Stalk incorporates multiple LED options, including white, red, blue, green, and infrared (IR) illumination. Users can quickly select the appropriate output for the task at hand—white light for visibility, colored LEDs for preserving night-adapted vision, and IR illumination for use with night vision devices (IR does not emit visible light). An integrated Identification Friend or Foe (IFF) beacon with a dedicated control switch allows simultaneous use alongside the primary light for enhanced signaling capability. Each lighting mode offers multiple brightness levels, including low, medium, high, and strobe, giving users the ability to balance output and runtime based on their environment. The white LED delivers up to 76 lumens on high with extended runtime, providing reliable illumination for both immediate tasks and sustained use. Built for secure, hands-free operation, the Sidewinder Stalk supports multiple mounting configurations, including helmet systems, MOLLE platforms, and direct attachment to gear or headwear. The push-button power switch and pull-to-turn rotary selector help prevent accidental mode changes, ensuring consistent performance under stress. Constructed from high-impact nylon with a gasket-sealed, corrosion-resistant design, the Sidewinder Stalk is built to withstand harsh conditions. With an IP67 rating for dust-tight and waterproof operation up to 1 meter, and tested to MIL-STD-810H durability standards, it delivers dependable performance in demanding tactical, industrial, and outdoor environments.
