the AA Maglite be very bright for its size . with fresh battery , it have the potential to lighten up a moderate size room under very dark condition . Mine have be 100 percent reliable , even when drop several time . accident happen , and my Mini AA be all scratch up and beat up -lrb- the black finish have partially come off from be drop so often -rrb- , yet it continue to work -lrb- even when drop on cement from 5 foot up on multiple occasion -rrb- . the only part I have have to replace be the bulb . while not as bright as higher tech surefire and similar flashlight , the Maglite AA be the most reliable and toughest flashlight I have owneed .
