Are you sure armytek doesn't already do this? Have you taken one apart? I havnt, and can only judge their quality from the outside. Which to me seems better than most. I ony have 2 armytek tho, and they have worked flawlessly. One is a few years old alredy. I don't have the Klarus but since they claim 2000 fl1, that means at least 30 seconds in, its still outputting 2k lumens otf, which is really all I would need/expect out of a light that size. Just a burst mode really to wow your non flashoholic peers
Others have taken AT lights apart and posted photos.
