Choose from high quality flashlights for long range illumination at BrightGuy.com. In general, a flashlight with a long distance beam will need to be larger. The larger size is necessary to accommodate a larger, deeper reflector. The larger, deeper reflector concentrates the beam which allows the light to shine further than a smaller flashlight would. You may be surprised to learn that just because a flashlight has high lumens, the beam range may be far less than a flashlight with less lumens. It’s all about the reflector.
