While packing a lot of Lumens is impressive for a flashlight, it is not always necessary to use a lot of Lumens for any activity. Tactical and pocket flashlights used by soldiers and police officers, for example, normally deliver anywhere from 100 to 1,000 Lumens. If you keep that in mind, then you shouldn’t be too concerned about how many Lumens your flashlight should have for indoor and outdoor activities. A high-quality flashlight like our best pocket flashlight today (Olight's S1R Baton) is plenty bright enough for most of us. If you want a flashlight that is exceptionally bright, go for the Fenix E30R with 1600 Lumens.
