SureFire HL1-B-TN Helmet Light - White & IR LEDs, 19.2 Lumens, Tan The SureFire HL1-B-TN HelmetLight is a compact, mission-ready hands-free lighting solution engineered for military, law enforcement, and tactical professionals. Featuring three white LEDs delivering up to 19.2 lumens for close-work tasks and two infrared (IR) LEDs providing a maximum output of 2.5 lumens for use with night vision devices (NVDs), this light covers every operational scenario. A dedicated IR Identify Friend or Foe (IFF) beacon further enhances safety by allowing friendly forces equipped with NVDs to quickly identify the wearer. Output is precisely controlled via two multi-position toggle switches and a pressure switch that cycles through low, medium, and high intensity levels. The ambidextrous mounting system attaches securely to any Modular Integrated Communications Helmet (MICH) and allows 360-degree rotation across 20 click-stop positions, ensuring the light is always pointed exactly where needed. Constructed of fiberglass-reinforced nylon polymer and neoprene, the HL1-B-TN is o-ring and gasket sealed for reliable waterproof performance in all weather conditions. Product Highlights Dual LED System: Three white LEDs (up to 19.2 lumens) for general tasks and two IR LEDs (up to 2.5 lumens) for use with night vision devices, plus a dedicated IR IFF beacon for friendly-force identification. Precise Output Control: Two multi-position toggle switches and a face-mounted pressure switch allow independent control of the IR IFF beacon, white/IR emitter selection, and three-level intensity cycling (low, medium, high). 360-Degree Rotatable Mounting: Included ambidextrous MICH-compatible mount features 20 preset click-stop positions for true 360-degree rotation, enabling precise light direction and quick attachment or removal. Waterproof and Durable Construction: O-ring and gasket sealed body built from fiberglass-reinforced nylon polymer and neoprene withstands harsh field conditions and all-weather use. Extended Runtime on a Single Battery: Powered by one CR123A lithium battery, with white LED runtime up to 48 hours on low and IR IFF strobe runtime up to 120 hours.
