The white light and colored light are controlled separately and can be turned on at the same time. The button with power icon controls the white LEDs and the button with C icon is for multi-color LED and the button with sun icon is for instant turbo and strobe function. 


White light 


Press and hold the button with power icon for 0.5 seconds to turn the light on or off. 


Output selection 

Press the button with power icon to cycle through five brightness levels in the order of Turbo>Eco>Low>Mid>High when the white light is turned on. 


Colored light 


Press and hold the button with C icon for 0.5 seconds to turn the light on or off. 


Output selection 

Press the button with C icon to cycle through four output options in the order of Blue>Green>Red>White when the colored light is turned on. 


Instant turbo 

Press and hold the button with sun icon for 1 second to activate turbo mode directly. To return to previous condition, just press the button again. 


Instant strobe 

To activate strobe mode, just press the button with sun icon. It will flash between 6Hz and 15Hz every two seconds. Press the button again will return the light to previous condition. 


Battery level indicator* 

The battery level indicator lights up the multi-color LED for 3 seconds to show the remaining power of the batteries loaded. To activate the battery level indicator, just double press the C button when the light is turned off.

  • Green LED constant-on: sufficient power level
  • Blue LED constant-on: high power level
  • Red LED constant-on: low power level
  • Red LED flashing: critical power level

*The battery level indicator only supports 18650 Li-ion rechargeable batteries. 


Intelligent memory circuit 

The flashlight memorizes the last brightness level used but it will not remember strobe mode. The next time you turn the flashlight on, it will light up at the last used brightness level. 


Over-heat protection 

The light will accumulate a lot of heat when it is working at high lumen output levels. The flashlight will automatically adjust the output to prevent the light from overheating. If non-stop full output is needed, just press the power button again. 


Battery Replacement 

Unscrew the tail cap to insert the batteries with the anode side (+) toward the light head, screw the tail cap back on. The light can be powered by two 18650 batteries or four CR123A batteries loaded in the correct battery compartments (as the diagram below shows). Under this condition, only the corresponding LED will light up and the runtime of each brightness level remains the same but the output is reduced by half. 


Usage & Maintenance

  • Please don't disassemble the sealed head, doing so can cause damage to the flashlight and will void the warranty.
  • We recommend the use of high quality battery. If the flashlight is not to be used for an extended period, remove the battery, or the flashlight could be damaged by electrolyte leakage or battery explosion.
  • The flashlight may be accidentally activated when stored, transported or placed in a pocket. Unscrew the tail cap one-half turn or take out the battery to avoid unwanted operation.
  • The O-ring may be worn out after using for a long time. If this happens, please replace the O-ring with a new one to keep the flashlight properly sealed against water.
  • Please clean the contacts of your light from time to time, especially if the light flickers or doesn't light up. There may be several reasons for a flickering or not working light: 
    Reason A: The battery needs replacing. 
    Solution: Replace the battery (Please confirm the correct orientation of positive and negative ends). 
    Reason B: The threads, PCB board contact or other contacts are dirty. 
    Solution: Clean the contact points with an alcohol soaked cotton swab.

If the above methods don't work, please refer to the warranty policy. 



LD75C is a high-intensity lighting device capable of causing eye damage. Avoid shining the light directly into anyone’s eyes.

High quality Flashlight- with Alternative Red / Green / Blue lighting. Love using it on the beach.

Thomas Kuc

Typical rock solid Fenix build/design, intelligent, useful output levels and excellent run times-the max output is more than most will ever need, certainly more than we will ever need. The colors really are used much more than we had thought, especially red, when we are hiking into the woods to get to our favorite star gazing spot. Being able to use the light with less than a full compliment of batteries is an important safety factor for us as is the ability for the light to run on the cr123 batteries. If you can buy only one light this is the one to have and of course Fenix Lighting is the best place to purchase the light-great people/service and advice.

Gregory Litzo

Have used this for several years hunting. It is an outstanding light. Multiple colors are really great. I have used this coming out of the woods at night. Red color does not spook animals and white illuminates the woods farther than you can see. I highly recommend this light.

Beautifully crafted multi purpose light

Mike Morrison

Just got in my LD75C. I own many other Fenix and Nitecore lights including the TK75, PD35.. etc.. The LD75C is a true all in ONE light refined product that was even better then I was expecting.
1-Amazing solid build and best Fit/Finish I have seen of any light.. The Anodizing of a matt finish of extremely high grade and the machined grip has beveled edges unlike most other flashight.. The fit/finish even puts surefire to shame.
2-The carrier free drop in battery compartment is great
3-The light beam patterns are great.. the main quad beams has a very similar beam pattern and center spot as the PD35.. just a slightly smaller center spot then the pd35 but is still much larger then the TK75. And the 4000 lumens really throws surprisingly far for a larger spot.. The multi color LED are MUCH brighter then I was expecting. The Red could light up a whole back yard. The White center LED is a FLOOD light which is really nice too.
This feels like a work of art and solid build that would last for generation.

I have 3 tk75s two 2900 and one 2600 along with a tk70 and a pd35 and all of them were my favorite for one purpose or another until I found the ld75c. It is by far the best flashlight purchase I have made, which I have thought with every Fenix light I have, but the color functions are great for anything done at night without taking away or dulling your normal vision along with a whooping 4000 lumens and a bounus 200 with both white lights turned on. It has virtually replaced all my other lights due to all its functions along with its compact size and light weight. I have put my light to the test from A to Z and then some and not once have I thought this or that could be better or they should have done this and it would have been better. Hats off to Fenix !! I can say without a doubt the only other flashlight brand I will have is one I was given as a gift and most likely just long enough to re-gift.
