I received my ordered Eagletac MX25L3C Nichia 219 LED kit flashlight, charged 3 each 18650 batteries, installed the optional button rear tail cap, read instructions, powered it on, then verified basic functionality. Then examined one of the filters and found the included parts were apparently not designed for this model though can be adapted for use. What I will describe below could more easily be described using pictures, however that will take more effort than I wish to deal with at the moment. In any case as someone working in test engineering for decades I am used to making technical descriptions. Note last Wednesday posted my first question on the forum.

The kit model contains these filters:
ET54 diffuser filter, ET54 yellow filter, ET54 red filter, ET54 green filter, ET54 blue filter
Did find a website selling them for $22. All the filters have identical glass diameters, thickness, and share the same black 2.4375 inch diameter ET54 plastic ring mount holders. My main interest was with the diffuser filter because a primary use for this person given the high CRI 92 index Nichia 219 LEDs, is to evenly illuminate large photographic artwork. There is no information on the Eagletac website about using the filter kit and some other vendors simply relate the front anodized steel kit bezel is removed so a filter can replace it.
Each of the 0.34375 inch deep ET54 plastic rings contain an obvious front side with a similar cutout design to the 0.8125 inch deep steel bezel. The outside plastic surface is lined to aid grip. Glass elements can be popped out the rear (flashlight body end) by applying modest pressure to overcome small detents. From the flush rear end of the ET54 plastic rings, external threading continues for 0.125 inch thus the ring is made for mating. The diameter of the threading is exactly the same as the threading on the camera housing over which the inside steel bezel internal threads mate. However the ET54 plastic rings don't mate (there would be no purpose to do so) with that bezel because internal threading in the bezel begins 0.125 inch deep from its rear side although since it does mate to the identical external threading of the flashlight housing what ought mate to the ET54 plastic rings would have identical internal threading to the bezel.
Accordingly in order to mate one of the ET54 plastic rings to the flashlight housing there would need to be a short depth plastic ring part open on both ends with internal threading that would thread into both elements. Apparently such a part does not exist though the plastic design would be trivial? Instead to use a filter, one can pop out the glass and loosely lie it atop the bezel whiteglass lens which can then be screwed onto the body. Note the whiteglass lens has a diameter that exactly fits the bezel snugly though will fall out if a removed bezel is oriented front up. Thus please be careful to only unscrew or reinstall the bezel while the camera is pointed down. The diameter of the filters is smaller than the whiteglass lens so obviously was not meant to be used loosely in this manner however once screwed down fully the filters are snug so it works. Because the filter glass makes intimate contact with the multicoated whiteglass lens either could be scratched which is not good. Tonight I will find a way to shim the two glass elements away from each other maybe using thin wire bent into a circle. I will contact my vendor, Andrew & Amanda's site to find out what they know.
