This flashlight will easily light up a dark room at night to the point where you can see every detail around you, a little bit like the tactical flashlights you see in TV shows when the hapless team goes exploring the derelict spaceship or abandoned warehouse or cave or what-have-you. And it has a pocket or belt clip so that you could hang it from a belt or similar.
Considering the low price and the bright performance, this is a great buy.
