Origin: Mainland China Light Source: LED Bulbs Model Number: Infrared LED Flashlight Material: Aircraft Aluminum Alloy Chip: IR 850nm or 940nm Powered by: 1x 18650 Rechargeable Battery Battery Input Voltage: 3.7-8.4V Waterproof: Splash Proof Only Weight: 90g Length (Zoom In): 128mm / 5.07in Length (Zoom Out): 132mm / 5.19in Operating Temperature: -25°C to 50°C 5W 850nm 940nm Infrared LED Flashlight, IR Torch, Zoomable Infrared Illuminator for Night Vision Scope Features: 1. 5W Invisible IR Light This is not a regular flashlight with white LED for general lighting. Utilizing an infrared 850nm LED emitter, this illuminator emits high-power, invisible IR light. Note: No visible light is emitted to the naked eye (only a faint red glow may be seen at the LED to indicate operation). 2. High-Quality Material Constructed from high-strength aircraft aluminum alloy with a three-stage hard-anodized finish for durability, wear resistance, and splash-proof protection. Housing diameter: 25.4mm. Compatible with standard 25.4mm mounting rings and systems. 3. Single Lighting Mode & Telescopic Zoom Features one constant-on mode (100% output). The flashlight head extends or retracts to adjust focus and beam intensity for optimal illumination. 4. Adjustable Focus Lens Rotary zoom focusing allows transition between a tight spotlight for long-range use and a wider flood beam for close-range coverage. Designed for enhanced long-distance performance compared to fixed-focus illuminators. 5. Long-Range Performance Effective illumination distance exceeds 600 meters (2000 feet) for the 850nm model and 300 meters (1000 feet) for the 940nm model. Suitable for outdoor applications including wildlife observation and target identification.
