when everyone say mag light be `` top of the line '' they be be incredibly naive ! try look into some real flashlight like Surefire , Fenix , and huntlight ! mag light even measure in candlepower , which grossly exaggerate brightness too . you turn they on and they be bright , but in 10 minute it 'll get dimmer . I own a flashlight by fenix which be easily 5 time as bright as this and will fit in the palm of my hand ! before you buy this light , consider the p1dce by Fenix , or the g2 from Surefire . thank you !
