ON
With the light turned off, press and hold the Master switch for 0.5 seconds to enter General mode, press and hold the Auxiliary switch to enter Flash mode.
OFF
With the light turned on, press and hold the Master or Auxiliary switch to turn off the light.

Mode Switching
In General mode, single click the Auxiliary switch to enter Flash mode.
In Flash mode, single click the Master switch to enter General mode.

Output Selection
With the light on General mode, single click the Master switch to cycle through Eco→Low→Med→High I→ High II→Turbo.

With the light on Flash mode, single click the Auxiliary switch to cycle through Strobe→SOS.

Instant Turbo
In any status with the light unlocked, press and hold the Master switch for 1.2 seconds to enter Turbo mode, click once on any switch to enter the last-used General mode.

Instant Strobe
With the light off and unlocked, press and hold the Auxiliary switch for 0.5 seconds to enter Strobe mode, or single click the Auxiliary switch on General mode to enter Strobe mode.

Intelligent Memory Circuit
The light memorizes the last selected brightness level on General mode. When turned on again the previously used brightness level will be recalled.

Battery Level Indication
When the light is off, single click the Auxiliary switch, the battery level indicator between the switches will display the battery status for 3 seconds. (Single click the blue button on the battery holder to check the battery status with the battery level indicator displayed).

  • Green constant on: saturated
  • Green flashes: sufficient
  • Red constant on: poor
  • Red flashes: critical

Lockout Function
Lock: With the light unlocked, simultaneously press the two switches for 3 seconds, the light will blink twice to indicate locked status.

Unlock: With the light is locked, simultaneously press the two switches for 3 seconds, the light will be unlocked and activated on last used brightness.

In locked status, clicking or pressing the switches will activate 2 one-second blinks to indicate locked status.

Intelligent Overheat Protection
The light will accumulate a lot of heat when it is working at Turbo mode and therefore has two levels of protection.  1) When the light is overheated up to 65 ℃ (149 F) or above, the flashlight will automatically downshift the output to 2500 lumens or 2) when the temperature is lower than 65 ℃ (149 F), after 3-minute working on Turbo, the light will slowly downshift to 2500 lumens within 30 minutes, to protect from high surface temperature and avoid risk of damaging your light.

Low-voltage Warning
When the voltage level drops below the preset level with the light switched on, low voltage warning will be activated automatically, then the battery level indicator between the switches will display red to remind battery replacement or charging. The flashlight is programmed to step down automatically to a lower brightness level until Eco output is reached. To ensure normal use, the flashlight will not turn off until the battery level runs out or once the battery over-discharging protection activates.

Note: This only works on 18650 Li-ion battery.

Charging
The battery holder features charging function with a standard Micro USB port.

  1. Take the battery holder out of the light, plug the USB port of the charging cable into any USB power supply. and plug the Micro USB side of the charging cable into the charging port of the battery holder.
  2. The charging indicator will display red while charging, and will turn to green when fully charged.

Note: Avoid contact with conductive objects like coins, screws, and keys when removing the battery holder from the light, to protect from static discharge which will damage the circuit boards

Battery Replacement
Unscrew the tail cap to take out the battery holder, and then insert the batteries in accordance with the polarity marks. After loading the batteries into the holder, insert the holder with its convex top towards the light head. Screw the tail cap back on.

    Meh….Long time Fenix user and honestly i was expecting more. I have the 3000 lumen 2 18650 cell light (i forget the model) and IMHO it is a much better value and almost as bright

    Was this review helpful to you?

    I like the brightness and sturdiness of the flashlight but I do not like the on/off mechanism. In an emergency it is too slow to find the little on/off button and the strobe comes on first and I have to switch it to a constant beam. I much prefer the big on off button on the end of a flashlight as you always know where it is.

      Loren – sounds like you are turning the light on using the Auxiliary Mode (the left button). If you turn it on using the General Mode (the right button), it will turn on at the last level used and will then cycle through all the modes. I’ll email you a copy of the operating instructions on it, or they can be found on our page for the TK75.
