Well, I suppose if you're speaking purely flood, the ThruNite TN36-UT is supposed to run 3h14m at 2500 lumen. The NiteCore TM26 should run at least 2h30m at 1900 lumen. Although the ThruNite won't throw as far as the NiteCore it definitely has more flood and a longer runtime. Although I'm not sure what mAh battery the TM26 was tested with so its runtime numbers could be conservative.
