I have couple of 2-aa , 3-d cell and a 5-d cell maglite for 20 year . they never fail . the only time it fail be when the battery melt and glue everything shut inside . it be impossible to clean it out . I also have a bunch of led flashlight from the old 1 watt to the newer 3 watt lead . the led be much brighter but blue\/white\/cold in color . so , the LED be not dense enough . it will not reach far . the led go about 20-25 foot max and everything be fuzzy . the maglite on the other hand , be warm\/orange in color . it be like a fog light that can go up to 50 foot . it be not as bright as the led but it be much much clear and sharper to see what be at the far end . I use the led mostly for go behind the desk\/under the table kinda work . but for real work like go under the crawl space or go up in the attic , I have get to use the Maglite . the lead just will not cut it . I replace the bulb with the newer xenon light bulb . this light bulb make the Maglite much better . it be brighter and whiter but at the same time be still warm\/orange in color . so , it be still dense enough to see far and sharp . beside use the Maglite as a flashlight , you can also use it to crack and smash anything you want and it will not compliant . 5 star !
