Rated 3.00 out of 5 based on 2 customer ratings
(2 customer reviews)

The Fenix TK25IR is a top flight 1000 lumen flashlight fitted with a CREE XP-G2 S3 LED and also has the ability to be switched to a fully functioning infrared light illuminator. The 850 nm wavelength infrared light has two outputs of 3000mW and 1000mW. Infrared light is invisible to the human eye, but can be a perfect illuminating enhancer to your monocular or scope night vision device. This enhanced illuminator will supply more light for a longer range of vision and better image clarity to certain night vision devices.

The patented switching mechanism makes the TK25IR easily switched into either flashlight mode or IR mode with no questions of which is activated.  Additional features of the flashlight include 4 lighting modes and strobe function,  dual layer body for additional impact resistance, IP68 waterproof/dust proof, and tactical tail switch.   A full range of gun mounting accessories are also available separately for this device.

    It is high power with both white and IR light. I light up fields with the white light and my gen1 NV scope loves the IR light it puts out. My biggest complaint is it is not a perfect 1″ dia so I did have to file down my holder, and it does NOT have a focusing lens. The throw is good but I have cheaper lower lumen IR illuminators that go as far by making use of a lens focus. Most NV scopes have low fields of vision and magnification that would definitely benefit from a focusing lens as most of the light it puts out is wasted outside of the scopes FOV. Iwould definitely buy a focusing attachment if they sold one for this light. For $100, I suppose you can’t have everything.
