I have had to many lights well before I found this site. I found this board while looking for my "unicorn" after a major shift in my needs/wants/use of/in a light changed. I had a lot to catch up on. I have or at least got close to finding a "unicorn"; a single cell, edc sized light that was as bright & had the throw of a search light, could light up a field like the sun with a floody beam + run all night@300L or so. Hank lights have gotten me the closest to checking all the boxes. The D4k w/W1 throw+351s flood works well as does the slightly larger D4sv2 with the same pairing, then the DT8k w/throw & flood optics raised the bar even higher. As all are duel channel lights the run times & heat management are good as long as you're just using one or the other channel at reasonable outputs. To much is never enough so I added a D18 w/12 flood+6 throw optics AND a DM1.12 to the mix. Bigger really is better, at least for throw/flood/run times are concerned. EDC size suffered BUT both have been used as an EDC light more than once. I've got 26 Hank lights at last count ranging from the D2 to a K1 & now the M44 duel channel light is out. Of course none of this touches on the Acebeam, Fenix, Olight, Zebra, Sofirn. Maglite, Skilhunt, etc lights I have now. To many? Yea I don't have enough pockets or belt space for All of them but I do have the right light for all my needs now; I just haven't found a true unicorn, yet
