Hi, guys.
We have an 850 nm infrared flashlight K3-i8. It is equipped with one 850 nm 5000mW infrared LED lamp and beams a maximum of 350 meters long-range distance. This infrared flashlight has received good reviews from many users.
Today I introduce a new product: 940nm infrared flashlight K3-i9. Compared to 850nm, infrared light at 940 nm is more invisible.
The human eye can perceive visible light with wavelengths ranging from 400nm to 750nm. Light with wavelengths outside this range is invisible light. Infrared wavelengths are between 760nm and 1000nm and are invisible light. Using the invisible characteristics of infrared light, equipped with a night vision device, you can observe people or objects at night without being noticed. Infrared lighting is ideal for the following groups of people: police, military, government agencies, law enforcement officers, hunters, farmers, and people with night vision goggles.
CYANSKY K3-i9 is a high-power long-range infrared tactical flashlight specially designed for night hunting, observation, and tactical tasks. Equipped with one Osram 940 infrared LED, better hidden the palm-sized K3-i9 can reach a maximum of 150 meters beam distance without being exposed. The single tactical tail switch with one output design allows extremely easy operation. Additionally, the double gold-plated spring against violent impacts allows K3-i9 extremely reliable for shooting or hunting.
We are looking for reviewers for infrared flashlights. If you are interested, please PM us.
