Vcsel 850nm/940nm：

Vcsel 850nm/940nm LED today's smallest and most advanced infrared LED with high efficiency, low thermal resistance. It can produce a powerful punch with approximately 100-500 meters+ range with focused beam. (The farthest can reach more than 500 meters.)

Not all infrared cameras and night vision goggles can receive 940nm infrared light. This is because 940nm is much further away from the visible spectrum than 850nm, which makes it harder for camera sensors to pick up. Check that the camera device you are using is compatible before purchasing. Please beware that: you won't see any light with your bare eyes (only a small and faint red glow on the LED to show you that the torch is on).
