Streamlight Sidewinder Stalk Features The Streamlight Sidewinder Stalk mounts its LED cluster on a flexible stalk rather than a fixed housing so the beam can be bent and aimed independently of head position. A push-button power switch and a pull-to-turn rotary selector knob work together to prevent accidental mode changes while still allowing quick selection of LED color. Multi-fuel capability lets the light accept AA alkaline AA lithium or CR123A lithium cells which means an operator can keep it running on whatever battery is on hand. The separate IFF switch with its center off position and two on positions keeps the identification beacon fully independent of the main light functions. A durable clip attaches the Sidewinder Stalk to a helmet or MOLLE vest giving hands-free lighting without extra hardware. At 5.51 inches long and roughly 2.88 to 3.20 ounces the light adds minimal bulk to a helmet or chest rig setup. The housing is IP67 rated dust-tight and waterproof to one meter for thirty minutes with O-ring and gasket sealed openings and it is tested to MIL-STD-810H Method 512.6 for 3-meter impact resistance. Built with high impact polymers and assembled in the USA the Sidewinder Stalk is backed by a 1-year limited warranty for dependable long-term service.
