Need some advice----I'd like to replace the factory incand bulb and maybe the entire reflector assembly with a drop-in LED setup for one of my Surefire M3's using two AW 17500 Li-ion cells. Are there any options that would output in the same ballpark as the Malkoff M60? I remember someone used to make a drop in "tower" but can not remember who...or if it was great or just so-so. (BTW I tried search and got too much of nothing.)
