For projects that require concealment and high requirements for animal disturbance, such as wildlife protection research projects, it is recommended to use 940nm infrared fill light, because the infrared light it emits is invisible to the human eye, has better concealment, lower loss rate, and less disturbance to animals. In addition, the penetration ability of 940nm infrared fill light is stronger than that of 850nm, and it can penetrate thicker objects, which is suitable for a wider range of application needs, such as shutter remote control, smart home, drone, infrared heater and other applications.

For applications that require lighting effects and durability, such as lighting of equipment such as infrared surveillance cameras and infrared night vision devices, and infrared remote controls for controlling home appliances such as televisions, air conditioners, and audio, 850nm infrared fill light is a more suitable choice. The wavelength of 850nm is between visible light and infrared light, and its lighting effect is better. It can be perceived by the human eye as a weak red light. At the same time, 850nm infrared fill light has good durability and a long service life.

In summary, the choice of 850nm or 940nm infrared fill light depends on the specific application scenario. If you value concealment and less impact on animals, you should choose 940nm; if you need better lighting effects and durability, 850nm is a more suitable choice.
