FWIW. The LED inside most tacticals runs ~4V. That is more or less the voltage of one 18650. Some tacticals run two 18650's. Does that mean a brighter light? Maybe, maybe not. There will be some kind of diode driver that will drop the voltage before it hits the chip. With two batteries the manufacturer can boost output or boost endurance and anything in-between. That out the way, the reason I jumped in here was to tell you that the floodlight par excellence is the MagicShine bike light. I am in my 2nd week using one and I am glad I went against the tactical geeks and bought a bike specific head-light. Tacticals are great for throw but when I am riding at night I am much more concerned with right here than with what is 1/4 mi down the road! If the MagicShine were all flood and no throw it would still be a great light. It's hellaciously bright and that is a kind of throw all its own.

Ever notice that the tactical advocates are usually using two (and more) lights together? That is an attempt to get some flood out of what are otherwise pretty throwy lights. That is what I used to do with my 4AAA Ascent 1/2W LED Commuter Headlights. Run two of them and point one of them slightly cockeyed to the right to light up the gutter and keep me out of the storm drains! Now with one light I have the best of both worlds and it uses four 18650's for run-time that you measure in hours, not minutes. Seriously, the MagicShine beam is practically panoramic but it has a center cone that reaches out if you tilt the light up. The only thing better IMO would be two of them! I am not a MagicShine seller, just a MagicShine convert. You know how the newly converted can be...
