    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.

  • 18560 rechargeable batteries are the highest volume standard battery used in lighting products. They are a great alternative for products that utilize 2xCR123A disposable batteries. Not only are you being environmentally friendly by eliminating disposable batteries, 18650 rechargeable battery provides different levels of capacity for your exact need. For example, you can get 30% more capacity out of a ARB-L18-3500 compared to a ARB-L18-2600.

    In addition, Fenix batteries are built with safety in mind. There are built in features to prevent short circuits, design multiple layers of protection and the new button-top design. The high capacity 18650 Li-ion rechargeable batteries each provide protection circuits in the anode to help prevent short circuits, over charge/discharge and over heating. Each battery also includes pressure relief vents which expel waste gas in the rare case of an internal short circuit preventing an explosion.
