LED IR Floodlight 20W

Comparison of 850nm and 940nm infrared LED products and applications:

LED Infrared Light class burst into red (850nm) and no red burst (940nm) categories.

  Red explosive products using infrared led 850nm wavelength of emission control, use, close observation, dark red light will emit infrared light. Red explosive products without the use of a wavelength of 940nm LED infrared emission control, use, there is no bright infrared light surface and therefore more subtle. With a video camera in the 850nm wavelength sensitivity than in the 940nm wavelength sensitivity to 10 times better. So this has a slight red storm 850nm infrared light has a higher efficiency, it should be the first choice as an infrared lamp.
