Battery Type: 

CI7 requires a 18650 battery with 8A+ output to reach the maximum brightness and access the full function of the light, 

A regular 18650 usually has 5-6A output so the light might not reach the maximum brightness, or it might shut off abruptly. There are many 18650 batteries available that fit this requirement. Most IMR 18650 batteries are compatible as well. (Check the manual for details)


Switching between White and IR Beam: Hold the head of the light and pull it slightly outward. Rotate the head for 1/8 turn and it will click into the next position. You can see four light yellow LEDs when the light is set to the white output and four dark red LEDs when the light is set to IR output. (Do not look directly to the LEDs when the light is on)


Enable the Strobe Function: CI7 can be set to two user modes (Daily or Tactical mode). Strobe can only be activated in the Tactical mode. To enable the Tactical mode: 

  • Turn off the light at white output setting. 
  • Slightly loosen the tail cap. 
  • Tighten the tail cap while holding down the padded mode selection button. 
  • The light will blink (once for Daily mode and twice for Tactical mode)

IR Wavelength: 940 nm


What is the difference between ir illuminators with 850 nm and 940 nm wavelength?


The 850 nm wavelength is standard for most applications, including CCTV.

The light source does produce a faint red glow at direct exposure, but otherwise it is not visible to the naked eye. Most of the true Day/Night cameras with removable IR cut filter have great sensitivity to 850nm wavelength, that’s why they are so widely used for IR illumination.

The main advantage of the 940nm wavelength is that it is completely invisible.

The light source doesn’t emit any glow. This is imperative for law enforcement, military, traffic and railroad applications where red light can be interpreted as a signal. However, not all cameras are sensitive to 940nm wavelength. The illumination range is shorter, compared to 850nm wavelength. While selecting the 940nm IR illuminator, be sure that you really need it, and will be able to use it.
