Brief Introduction

K3-I8 is a long-range IR flashlight specially designed for law enforcement, military action, search & rescue, and hunting. Equipped with one 5000mW OSRAM IR850 LED, the palm-sized IR spotlight achieves a maximum 350 meters beam distance, which doubles that of a standard IR illuminator and greatly enhances the performance of a digital scope at night.

The infrared led flashlight K3-I8 is made of aero grade T6061-T6 aluminum with HAIII hard-anodized anti-abrasive finish. The special double gold-plated springs design ensures constantly reliable contact against violent impacts during shooting. Additionally, the IPX8 waterproof (2 meters underwater) and 2 meters impact-resistant performance allow K3-I8 capable of use for all weather in all rough environments.

Q1: What is an infrared flashlight? 
A: The infrared flashlight is also called IR torch, or IR flashlight, which comes with LED emitting lighting that falls beyond human’s normal visible spectrum. So, it’s invisible to the naked eye.

Q2: How do infrared flashlights work?
A: When you turn on an IR LED flashlight, you cannot see any beam. But if you take night vision equipment, the invisible IR flashlight will create enough light for the night vision device to use it as a light source and illuminate the area effectively, while keeping you not being exposed.

Q3: What does an infrared flashlight do?
A: Since infrared lights for night vision can light up an area while keeps hidden, it is widely used for military action, law enforcement, and hunting.

Q4: What LED K3-I8 is used?
A: The IR torch K3-I8 uses one 5000mW OSRAM IR850nm LED, which allows a clear view as far as 350 meters.

Q5: What is the difference between a normal LED and an IR LED?
A: LED is short for light emitting diode, which can emit light when an electric current passes through. Normal LEDs and IR LEDs are the same in appearance. However, for a “normal” LED torch, we can see the light beam while for an IR LED torch, it’s invisible to the naked eye and can be seen only when working with a camera or night vision device.

Q6: What is 850nm?
A: 850nm refers to the wavelength. Generally speaking, the wavelength of infrared light is from 720nm to 950nm. 850nm and 940nm are most commonly used in led illumination resources for IR flashlights.

Q7: 850nm vs 940nm IR
A: Both 850nm and 940nm IR torches are invisible. But they do have some differences and are used in different scenarios.

IR flashlight 850nm pros and cons

☑️ Better sensitivity for cameras

☑️ About 40-50% longer range

☑️ A better choice for hunting and most security applications

✖️ Not as covert as 940nm

IR flashlight 940nm pros and cons

☑️ More covert

☑️ Better for military operations or law enforcement where covertness is essential for safety

✖️ Performance reducing up to 40-50%

✖️ Requiring a very sensitive camera

Q8: What’s the most suitable use for K3-I8?
A: The IR illuminator flashlight K3-I8 adopts one IR850 LED, which is the best ratio of long-range to covertness. Thus, it’s a very good option for hunting and most security applications. However, if you require completely covert, IR940 would be a better choice. Just remember the range will be reduced up to 50%.

Q9: Do any animals see infrared light?
A: Like humans, most animals cannot see infrared light.

However, there are some species like vampire bats, bed bugs, and some snakes and beetle can use portions of the infrared spectrum for vision.

Q10: Can K3-I8 be an IR weapon light?
A: Yes, you can mount K3-I8 on a rifle with the gun mount. You can also take the remote switch for easier operation.

PS: Gun mount and remote switch are available for optional purchase.

Q11: Is K3-I8 rough enough for shooting?
A: Yes, it’s extremely tough made of aero-grade T6061-T6 aluminum with HAIII hard-anodized anti-abrasive finish. To ensure constant reliable contact, it has been specially designed with double gold-plated springs, buffering against the violent impact during shooting.

Q12: What about the weather ability for K3-I8?
A: Featuring IPX8 waterproof, 2 meters impact-resistant, and workable from -30℃ to 50℃, K3-I8 is competent for all seasons and weather use.

Q13: Is the IR light K3-I8 battery powered?
A: Yes, it can be driven by one separated 21700 or 18650 Li-ion battery. You will get a 5000mAh 21700 battery with TYPE-C charging port in the package.

Q14: How do I know if my infrared light K3-I8 is working?
A: Since the IR light is invisible, it’s difficult to tell whether it’s working with the naked eye. Then, please check the tail button and keep it pop-up when you do not use the light. To avoid accidental power on, we suggest you unscrew the tail by a half-turn to completely power off.

Q15: Are IR illuminators legal?
A: Yes, it is civilian legal. BTW, since K3-I8 is a high power infrared light and invisible to naked eyes, please avoid directly staring at the LED when the light is on just in case there is any possible harm to the eyes.
